Question

I am in the process of upgrading a PHP code base to be able to run on PHP5.3+ and I need a list of functions that make use of wrappers.

http://www.php.net/manual/en/wrappers.php

This page mentions; fopen(), copy(), file_exists() and filesize(). I know for a fact that there are other functions; file_get_contents(), file() and others.

Does anyone has a complete list? Or perhaps an easy way to “grep” through a directory to look for functions using wrappers?

Answer 1

grep the php source for php_stream_open_wrapper_ex calls, which should give the PHP_FUNCTIONs that directly interact with wrappers.

A rough and probably partially wrong list (-B 100 is not exact):

$ find . -name '*.c'| xargs grep -B 100 php_stream_open_wrapper_ex| grep PHP_FUNCTION
