Finding position of data in the array - PHP

Question

I have a PHP array, say,

$array = Array("Name1","Name2","Name3","Name4","Name5");

I want to find the position of these names in the array.

I want to return 0 for Name1 and 2 for Name3.

How can I do this?

array_search. BTW have you ever tried to look at ru2.php.net/manual/en/ref.array.php ? — kirilloid

Do you mean:


$key = array_search('Name1', $array);

Ref: array_search

$pos = array_search("Name3", $array);

Should be what you are looking for, note that to be safe, result checking should be using === (three equal signs) so that those returning 0 (if you are looking for thing in the first element) is also checked for type when you are comparing them in an if statement

if(array_search($name, $array) === 0)

Something like that:

<?php
   $array = Array("Name1", "Name2", "Name3", "Name4", "Name5");
   $searchValue = "Name1";
   $keys = array_keys($array, $searchValue);

   // test it
   print_r($keys);
?>
