How to get list of declared functions with their data from php file?
- by ermac2014
I need to get list of functions with their contents (not only the function name) from php file. I tried to use regex but it has lots of limitations. it doesn't parse all types of functions. for example it fails if the function has if and for loop statements.
in details:
I have around 100 include files. each file has number of declared functions. some files has functions duplicated in other files. so what I want is to get list of all functions from specific file then put this list inside an array then I will be using array unique in order to remove the duplicates. I read about tokenizer but I really have no idea how to make it grab the declared function with its data.
all I have is this:
function get_defined_functions_in_file($file)
{
$source = file_get_contents($file);
$tokens = token_get_all($source);
$functions = array();
$nextStringIsFunc = false;
$inClass = false;
$bracesCount = 0;
foreach($tokens as $token) {
switch($token[0]) {
case T_CLASS:
$inClass = true;
break;
case T_FUNCTION:
if(!$inClass) $nextStringIsFunc = true;
break;
case T_STRING:
if($nextStringIsFunc) {
$nextStringIsFunc = false;
$functions[] = $token[1];
}
break;
// Anonymous functions
case '(':
case ';':
$nextStringIsFunc = false;
break;
// Exclude Classes
case '{':
if($inClass) $bracesCount++;
break;
case '}':
if($inClass) {
$bracesCount--;
if($bracesCount === 0) $inClass = false;
}
break;
}
}
return $functions;
}
unfortunately, this function lists only the function names..
what I need is to list the whole declared function with its structure..
so any ideas?
thanks in advance..
