OVERRIDING functions

[Guest]

I want that every time the built-in 'mysql_query' function is called another user function is also called.
But i can't call the user function explicitly, I can only call the built-in function.

Any idea?

Much thx in advance.

You mean apart from changing the PHP source and recompiling?
No, no idea.

Do the two functions have the same name?

What two functions?


Get the PHP source: http://www.php.net/downloads.php

Edit "php-src/ext/mysql/php_mysql.c".
Compile.
Voila!

I'm guessing he's referring to both the built-in function and the user one.

This is kinda clunky, but what you can do is dynamically rewrite the code,
replacing calls to mysql_query with mysql_query_use r.

Add this snippet to the beginning of your code:

if(!$eval) {
function mysql_query_use r() {
$args = func_get_args() ;
print_r($args);
call_user_func_ array('mysql_qu ery', $args);
}

$eval = true;
$code = file_get_conten ts($_SERVER['SCRIPT_FILENAM E']);
$code = preg_replace('/(?<=\\s)mysql_q uery\\s*\\(/', 'mysql_query_cu stom(',
$code);
eval("?>$code") ;
exit();
}

This won't work, of course, if the call to mysql_query is buried in an
included file.
