$textvar = "Text(foo): " . func1("foo (bar)") . func2 ($some_arg);

What regex can I use to extract the above function names to verify the existance of these functions?

  • Do you mean Text in Text(foo)? Commented Apr 18, 2011 at 11:24

  • I'd assume he means func1( and func2( and wants Text( and foo( ignored because they appear in strings. If so, a regex will be insufficient. See token_get_all. Commented Apr 18, 2011 at 11:33

How about this?

<? if(function_exists($function_name)) {
    //do something; 
}
?>
