copied!<p>Using regexes to parse code is a REALLY bad idea. Take a look at <a href="http://php.net/manual/en/book.tokenizer.php" rel="nofollow">PHP's Tokenizer</a>, which you can use to parse PHP code into an array of tokens. You can than use that array to find the information you need.</p> <p>You can also look at <a href="https://github.com/Andrewsville/PHP-Token-Reflection" rel="nofollow">PHP-Token-Reflection's source code</a> as an example of how to get meaningful information from those tokens.</p> <p>Basically, you would need to find <strike>T_PARENT occurrences</strike> T_STRING occurrences with 'parent' as the string contents, followed by T_DOUBLE_COLON, followed with another T_STRING that contains the method name, than go forward and start counting the depth of the parentheses - whenever you get to an '(', increase the counter by one. Whenever you get to an ')', decrease the counter by one. Keep a record of everything you find in the process until the counter gets back to 0.</p> <p>Something like that should work (not actually tested):</p> <pre><code><?php $tokens = tokens_get_all(...); for ($i=0, $size = count($tokens); $i < $size; $i++( { if ($tokens[$i][0] === T_STRING && $tokens[$i][1] === 'parent' && $tokens[++$i][0] === T_DOUBLE_COLON && $tokens[++$i][0] === T_STRING) { $method = $tokens[$i][1]; $depth = 0; $contents = array(); do { $contents[] = $token = $tokens[++$i]; if ($token === '(') { $depth++; } elseif ($token === ')') { $depth--; } } while ($depth > 0); echo "Call to $method with contents:\n"; print_r(array_slice($contents, 1, -1)); // slices off the opening '(' and closing ')' } } </code></pre>
