Increment index of an array in PHP -

-

i want find element placed right after $input seems type of index not int , because of can not mathematical operations on . 

$index = array_search($input,$tmp); $index += 1 ; $hold = $tmp[$index]; echo $hold;

don't on think it, use array_values():

$index = array_search($input, array_values($tmp)); $index += 1; $hold  = array_values($tmp)[$index]; echo $hold;

you want checking make sure key returned array_search() , check next index isset().

$vals  = array_values($tmp); $index = array_search($input, $vals);  if($index !== false && isset($vals[++$index])) {     $hold = $vals[$index];  // has incremented ++$index     echo $hold;  }
