multidimensional array recursive search

[monkle]

PHP Version 5.1.2-1.dotdeb.2

I am doing something right now that requires that I check for the existence of a value in a multidimensional array. It doesn't matter at what level in the multidimensional array the value is found, I just need to know if it's anywhere in the array or not.

I have been searching on this for a while, first in the pho.net documentation and then on Google, and while I find a plethora of information on searching arrays, I have had no success in dealing with multidimensional arrays. Any input would be greatly appreciated.

The trouble with looking for prebuilt code on searching multidimensional arrays is that the code must match the structure of the array. And the structures of multidimensional arrays can vary grandly.

What is the structure of your array?

The structure varies.

I finally found something that helped, which led to the following user-defined function:

protected function inArrayR($strVal, $arrHeap){
foreach ($arrHeap as $value) {
if ($strVal == $value){
return true;
} elseif (is_array($value)) {
if ($this->inArrayR($strVal, $value)){
return true;
}
}
}
}
