Xampp

Troubleshooting

Port 80 is being used by SYSTEM (PID 4)

Check with NET stop HTTP what's listening to port 80 Most of the time it's the IIS (WWW Publishing Service) or MSSQL Reporting Service

• WWW Publishing Service is active, uninstall!
• windows - XAMPP - Port 80 in use by "Unable to open process" with PID 4! 12 - Stack Overflow
• Unable to run Apache under Windows: An attempt was made to access a socket in a way forbidden by its access permissions - Super User
• iis - Port 80 is being used by SYSTEM (PID 4), what is that? - Stack Overflow

Virtual Hosts

Instead of using my-project.dev or my-project.local to differentiate domain names, I prefer to use subdomains like local.my-project.com.

This makes more clear what domain I'm developing for and it's easier to develop domain specific features like a redirect for my-project.com or my-project.de domains.

Certificates for localhost with mkcert

create certificates for local development domains with mkcert.exe

https://github.com/FiloSottile/mkcert

$ mkcert -install

Created a new local CA 💥

The local CA is now installed in the system trust store! ⚡️

The local CA is now installed in the Firefox trust store (requires browser restart)! 🦊



$ mkcert example.com "*.example.com" example.test localhost 127.0.0.1 ::1



Created a new certificate valid for the following names 📜

 - "example.com"

 - "*.example.com"

 - "example.test"

 - "localhost"

 - "127.0.0.1"

 - "::1"



The certificate is at "./example.com+5.pem" and the key at "./example.com+5-key.pem" ✅

<VirtualHost local.example.com:443>

    # ....

    SSLEngine on

    SSLCertificateFile "E:\WEB\example.com\example.com+5.pem"

    SSLCertificateKeyFile "E:\WEB\example.com\example.com+5-key.pem"

    ServerSignature On

</VirtualHost>

Options for DEV Environment

Most modern approach is Docker. Right now, I don't have the mental capacity to mess with it, but if, then Devilbox would be the way to go.¹

Neard seems to be an all in one portable dev package with Apache, Node.js, versions of php and even browsers to test. I think this could be ok to start with a vanilla webproject, dev machine.

WAMP Server is similar to XAMPP and comes with several PHP versions, but those cannot run in parallel.

WLS - Use LAMP stack in Microsoft Linux Subsystem - not sure if and how I can access files on the windows file system and is file access faster?

XAMPP is my choice for local development right now, because it runs flawless so far and just needed the option to run PHP 5.6 and any version of PHP 7 in parallel.

This is done by run PHP 5.6 as Apache module as indented and run all other versions in cgi mode.

PHP 5.6 and 7.x parallel on XAMPP

Run PHP 5.6 as Apache Module and PHP 7.4 as CGI

1. Download PHP 7.x Win32 Thread-Safe https://windows.php.net/download/

2. Edit httpd-xampp.conf add:

#

# PHP-CGI setup

#



# Put Authorization Header back to HTTP Headers

# If you are using Apache with CGI/FastCGI, then you might get an error message about missing authorization headers. This is because Apache does not, by default, pass authorization headers to PHP.



SetEnvIf Authorization .+ HTTP_AUTHORIZATION=$0



# PHP Versions



ScriptAlias /php74/ "E:/xampp/php749/"



<IfModule actions_module>

Action application/x-httpd-php74-cgi "/php74/php-cgi.exe"

</IfModule>



# Make directory executable

<Directory "E:/xampp/php749/">

    AllowOverride None

    Options None

    Require all denied

    <Files "php-cgi.exe">

          Require all granted

    </Files>

    # Where to find php.ini

    SetEnv PHPRC "E:/xampp/php749"

</Directory>



ScriptAlias /php73/ "E:/xampp/php7321/"



<IfModule actions_module>

Action application/x-httpd-php73-cgi "/php73/php-cgi.exe"

</IfModule>



# Make directory executable

<Directory "E:/xampp/php7321/">

    AllowOverride None

    Options None

    Require all denied

    <Files "php-cgi.exe">

          Require all granted

    </Files>

    # Where to find php.ini

    SetEnv PHPRC "E:/xampp/php7321"

</Directory>

3. Edit httpd-vhosts.conf

<VirtualHost *>

    DocumentRoot E:\WEB\tools.de

    ServerName local.tools.de



    # Run as CGI module

    <FilesMatch "\.php$">

    SetHandler application/x-httpd-php7-cgi

    </FilesMatch>

</VirtualHost>

4. Edit php.ini

   • Enable dynamic extensions (sqlite, curl etc)
   • extension_dir = "ext"
   • Certificate information curl.cainfo="E:\xampp\cacert.pem"
   • Activate Xdebug https://xdebug.org/docs/install

5. Set PATH to PHP 7.x to use latest PHP version on command line.

6. Now with PHP 7.x on the cli, set max php version to composer file in project to not accidentally update libraries that need to run on PHP 5, to PHP 7.

{



    "config": {

        "platform": {

            "php": "5.6.1"

        }

    },

    "require": {

        "symfony/yaml": "^3.2",

    }

}

Check with composer outdated what needs to be updated.

Composer

Change Composer Home Folder https://w3guy.com/change-composer-global-package-install-folder-windows/

Fake Platform, Ignore Extensions

Fake platform in config.platform in composer.json or use --ignore-platform-reqs when on cli php7.3-cli composer.phar update --ignore-platform-reqs

Example: Missing ext-imagick

ext-imagick is not installed but is a requirement for a package. Install the polyfill calcinai/php-imagick and set the config.platform key to the version. This way ext-imagick is seen as available, even if it's just the polyfill.

repositories key just loads a fork of calcinai/php-imagick that included some additional methods not in the original polyfill. (My changes are merged by now https://github.com/calcinai/php-imagick/pull/7)

{

    "require": {

        // "dev-feature" is the name of the branch

        "calcinai/php-imagick": "dev-feature"

    },

    "config": {

      "platform":{

        "ext-imagick": "3.4.4"

        }

    },

    "repositories": [

        {

            "type": "vcs",

            "url": "https://github.com/marcus-at-localhost/php-imagick"

        }

PHP_CodeSniffer (PHPCS+PHPCBF)

PHP CodeSniffer and PHP-CS-Fixer are similar tools

PHPCS seems to be more common. PHP Code Beautifier (PHPCBF) fixes the file after a defined rule set. PHP_CodeSniffer just notifies.

1. Install globally via Composer

https://github.com/squizlabs/PHP_CodeSniffer

2. Set Paths

For Sublime Text phpcs extension, set the paths to the *.bat

{

    // phpcbf settings



    // Path to where you have the phpcbf installed

    "phpcbf_executable_path": "E:/xampp/Composer/vendor/bin/phpcbf.bat",



    "phpcbf_additional_args": {

        //"--standard": "Squiz",

        "-n": "",

        "-s": "",

        //"--standard": "E:/xampp/phpcs/ruleset.xml"

        "--standard": "E:/xampp/phpcs/MyPSR12/ruleset.xml"

    }

}

3. check installed path for rules:

E:\WEB>E:/xampp/Composer/vendor/bin/phpcs.bat --config-show



E:\WEB>E:/xampp/Composer/vendor/bin/phpcs.bat --config-set installed_paths E:\xampp\phpcs

Using config file: E:\xampp\Composer\vendor\squizlabs\php_codesniffer\CodeSniffer.conf



Config value "installed_paths" updated successfully; old value was "/e/xampp/phpcs/"



E:\WEB>E:/xampp/Composer/vendor/bin/phpcs.bat --config-show

Using config file: E:\xampp\Composer\vendor\squizlabs\php_codesniffer\CodeSniffer.conf



installed_paths: E:\xampp\phpcs



E:\WEB>E:/xampp/Composer/vendor/bin/phpcbf.bat E:\WEB\site\models\netzwerk.php --standard=MyPSR2 -n

💡 To debug rulesets and find out what to exclude run:

phpcs temp.php --standard=Generic,Squiz,PEAR,PSR2,Zend -s

via https://stackoverflow.com/a/44937114/814031

5. Rule sets

Ref: https://github.com/squizlabs/PHP_CodeSniffer/wiki

I want tabs and some formatting from MySource. This seems to be ok:

<?xml version="1.0"?>

<ruleset name="MyPSR12">

    <description>PSR12 with tabs instead of spaces.</description>

    <arg name="tab-width" value="4"/>

    <rule ref="MySource">

        <exclude name="Generic.WhiteSpace.DisallowTabIndent"/>

    </rule>



    <rule ref="Generic.WhiteSpace.DisallowSpaceIndent"/>

    <rule ref="Generic.WhiteSpace.ScopeIndent">

        <properties>

            <property name="indent" value="4"/>

            <property name="tabIndent" value="true"/>

        </properties>

    </rule>



    <rule ref="Squiz">

        <exclude name="Squiz.Commenting.LongConditionClosingComment"/>

        <exclude name="Squiz.Commenting.ClosingDeclarationComment.Missing"/>

    </rule>

</ruleset>

Xdebug

Slows everything down. If not needed, disable it in main php.ini!

#[XDebug]

#zend_extension = "php_xdebug-2.9.6-7.3-vc15.dll"

Xdebug Issue "End of script output before headers: php-cgi.exe"

Server error! The server encountered an internal error and was unable to complete your > request.

Error message: End of script output before headers: php-cgi.exe

If you think this is a server error, please contact the webmaster.

Error 500 local.tools.marcus-obst.de Apache/2.4.12 (Win32) OpenSSL/1.0.1l PHP/5.6.8

This is caused when using a number as key of a query string like info.php?0=foo - which is weird.

ImageMagick Extension

Install he right version from here: https://mlocati.github.io/articles/php-windows-imagick.html (w32 Thread safe)

Once you downloaded the correct files:

1. Extract from php_imagick-….zip the php_imagick.dll file, and save it to the ext directory of your PHP installation
2. Extract from ImageMagick-….zip the DLL files located in the bin folder that start with CORE_RL or IM_MOD_RL, and save them to the PHP root directory (where you have php.exe), or to a directory in your PATH variable
3. Add this line to your php.ini file: extension=php_imagick.dll
4. Restart the Apache/NGINX Windows service (if applicable)

Polyfill ext-imagick

CGI Mode and php.ini

• add custom .user.ini to project root to overwrite certain settings

track_errors = On

Troubleshooting

Error 500: malformed header from script. Bad header=<br>

If your webserver throws a HTML 500 error and Apache error_log file shows "malformed header from script. Bad header=
", then you probably have a misconfigured php.ini file in your website root directory.

Missing Authorization Header in PHP running in CGI-Mode
