Question

I have the following PHP array:

Array
(
    [0] => 750
    [1] => 563
    [2] => 605
    [3] => 598
    [4] => 593
)

I need to perform the following action on the array using PHP:

1. Search the array for a value (the value will be in a
   variable; let’s call it $number). If the value
   is present in the array, remove it.

If someone could walk me through how to do that, it would be much appreciated.

Note: If it makes it any easier, I can form the array so the keys are the same as the values.

Answer 1

$array = array_unique($array) // removes dupicate values


while(false !== ($num = array_search($num, $array))){
    unset($array[$num]);
}
$max = max($array);

will search for all keys with value $num and unset them
