I couldn't find an easy way to search an array of associative arrays and return the key of the
found associative array, so I created this little function to do it for me. Very handy for searching
through the results of a mysql_fetch_assoc()
<?php
$a = array(
array('id' => 1, 'name' => 'oranges'),
array('id' => 2, 'name' => 'apples'),
array('id' => 3, 'name' => 'coconuts'),
);
function _array_search($s, $a) {
for($i=0; $i <= count($a); $i++) {
if (in_array($s, $a[$i])) {
return($i);
break;
}
}
return(FALSE);
}
//returns key 0 for the second element, 'id' => 1
echo _array_search(1, $a);
//returns key 2 for the second element, 'id' => 3
echo _array_search(3, $a);
//returns key 1 for the second element, 'id' => 2
echo _array_search(2, $a);
?>
