php - Find a value in an array -


what doing wrong following code? want compare if element $my_id present within array $arr. if present return true else return false.

for($i=0;$i<$cnt;$i++) {     if($arr[$i] == $my_id)     {         return true;     }     else     {         return false;     } }

you replace with...

return in_array($my_id, $arr);

...assuming don't want return false if first element not match.

if wanted, use...

return $arr[0] == $my_id;

if want leave code intact, move return false outside of loop body.
