This drove me mad for hours. Remember that the result of array_search might return the first
position in the array, which would be "0". However, I was testing for a false value by
doing this:
if(!$key){
return false;
}else{
return true;
}
when you should be doing this:
if($key !== false){
return $key;
}else{
return false;
}
Also, remember that you can search multi-dimentional arrays by specifying:
$key = array_search($your_val,$your_arr[0]);
or use and associative array by:
$key = array_search($your_val,$your_arr['array_name']);
Hope this saves you all some headaches :0)
