Contains lists of PHP symbols such as class names, INI values, function names, phpinfo() output, etc for each PHP version.
This list is built automatically daily.
This data can be used to determine if a given PHP symbol is available and valid for a given PHP version.
For example, to figure out of str_starts_with is available in a PHP version, look the %version%/function.php file for the function.
The main use case this data was built in the first place to work on a CanIUse-style lookup for PHP. This is work-in-progress at PHP.Watch.
