note 108783 modified in function.array-search by danbrown

I have just tried to add the function of recursive Array Search in order to return all finding keys in an array instead of the first matching result index, and further expanded search to contain needle instead of exactly matching: 

<?php
function recursiveArraySearchAll($haystack, $needle, $index = null) 
{ 
	$aIt = new RecursiveArrayIterator($haystack); 
	$it = new RecursiveIteratorIterator($aIt); 
	$resultkeys;
						
	while($it->valid()) { 
	if (((isset($index) AND ($it->key() == $index)) OR (!isset($index))) AND (strpos($it->current(), $needle)!==false)) { //$it->current() == $needle
	$resultkeys[]=$aIt->key(); //return $aIt->key(); 
	} 
							
	$it->next(); 
	} 
	return $resultkeys; // return all finding in an array
						
} ;
?>

To use the function on your array search:

<?php
print_r(recursiveArraySearchAll($your-array,'your-needle-to match','your-array-index-to-search') );
?>

Simple! and Enjoy! --was-- I have just tried to add the function of recursive Array Search in order to return all finding keys in an array instead of the first matching result index, and further expanded search to contain needle instead of exactly matching: function recursiveArraySearchAll($haystack, $needle, $index = null) { $aIt = new RecursiveArrayIterator($haystack); $it = new RecursiveIteratorIterator($aIt); $resultkeys; while($it->valid()) { if (((isset($index) AND ($it->key() == $index)) OR (!isset($index))) AND (strpos($it->current(), $needle)!==false)) { //$it->current() == $needle $resultkeys[]=$aIt->key(); //return $aIt->key(); } $it->next(); } return $resultkeys; // return all finding in an array } ; To use the function on your array search: print_r(recursiveArraySearchAll($your-array,'your-needle-to match','your-array-index-to-search') ); Simple! and Enjoy! http://php.net/manual/en/function.array-search.php
