Allowed memory size of 33554432 bytes exhausted (tried to allocate 93 bytes) error in php

Solution

As the others say, you created an infinite loop. Use a `for` loop instead.

for($counter = 1; $counter <= 3; $counter++) {
  if($_POST['additional_contact' . $counter] != '') {
    $_SESSION['contact'][$counter]['additional_contact'] = $_POST['additional_contact' . $counter];
    $_SESSION['contact'][$counter]['additional_int_prefix'] = $_POST['additional_int_prefix' . $counter];
    $_SESSION['contact'][$counter]['additional_prefix'] = $_POST['additional_prefix' . $counter];
    $_SESSION['contact'][$counter]['additional_first'] = $_POST['additional_first' . $counter];
    $_SESSION['contact'][$counter]['additional_last'] = $_POST['additional_last' . $counter];
  } else {
    $_SESSION['contact'][$counter]['additional_contact'] = null;
    $_SESSION['contact'][$counter]['additional_int_prefix'] = null;
    $_SESSION['contact'][$counter]['additional_prefix'] = null;
    $_SESSION['contact'][$counter]['additional_first'] = null;
    $_SESSION['contact'][$counter]['additional_last'] = null;
  }
}

Think about it: In your while loop, you test whether `$_POST['additional_contact1'] != ''` or not. But you never change that value again. So once it is `!= ''`, the condition in the while loop always evaluates to `true`.

Problem

I inserted the following code: ``` $counter = 1; while($_POST['additional_contact1'] != '' || $_POST['additional_contact2'] != '' || $_POST['additional_contact3'] != '') { if($_POST['additional_contact' . $counter] != '') { $_SESSION['contact'][$counter]['additional_contact'] = $_POST['additional_contact' . $counter]; $_SESSION['contact'][$counter]['additional_int_prefix'] = $_POST['additional_int_prefix' . $counter]; $_SESSION['contact'][$counter]['additional_prefix'] = $_POST['additional_prefix' . $counter]; $_SESSION['contact'][$counter]['additional_first'] = $_POST['additional_first' . $counter]; $_SESSION['contact'][$counter]['additional_last'] = $_POST['additional_last' . $counter]; } else { $_SESSION['contact'][$counter]['additional_contact'] = null; $_SESSION['contact'][$counter]['additional_int_prefix'] = null; $_SESSION['contact'][$counter]['additional_prefix'] = null; $_SESSION['contact'][$counter]['additional_first'] = null; $_SESSION['contact'][$counter]['additional_last'] = null; } $counter++; } ``` and I received this error: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 93 bytes) I tried to increase the memory limit with ini_set(), but it still won't work at 96M. What am I doing wrong with my code to make it need so much memory? How can I solve this problem?
