Why does my PHP script throw an Internal Server Error 500?
Internal Server Error 500 is usually caused by either a malformed cgi script or an invalid directive in an .htaccess file located either in the same directory as the page throwing an error, or in any directory above it.If you have just uploaded or editted an .htaccess file that includes mod_php related directives such as php_value ..., php_flag ..., these are invalid because PHP runs here as a CGI, not as mod_php. This means that you either need to comment out those invalid PHP-related directives from the .htaccess file by putting a '#' symbol before them, or you need to place your PHP-related directives in an "IfModule" container so that they can be ignored on our system without throwing an error. For example:
# php_value magic_quotes_gpc offPHP-related configuration settings must be put in either your /etc/php.ini file, a php.ini file that is in the same directory as an executing script, or be set inside the script with ini_set() function calls.
<IfModule mod_php4.c>
php_value post_max_size 20971520
php_flag magic_quotes_gpc off
</IfModule>
Note that certain PHP settings cannot be set with ini_set() and can only be set on our system in a php.ini file. See the PHP manual on ini_set() for details.
