Remove item from array if item value contains searched string character

Question

I have an array built from the URL of a webpage.

If an item in that array contains the ? symbol (The question mark symbol) then I want to remove that item from the array.

$array = ['news', 'artical', '?mailchimp=1'];

How could I do this? I've seen many examples where the searched string is the whole value, but not where it's just a single character or just part of the value.

Answer 1

http://www.php.net/manual/en/function.array-filter.php

function myFilter($string) {
  return strpos($string, '?') === false;
}

$newArray = array_filter($array, 'myFilter');

Answer 2

foreach($array as $key => $one) {
    if(strpos($one, '?') !== false)
        unset($array[$key]);
}

Answer 3

Use a closure...

$array = array_filter($array, function($value){
   if (strstr($value, '?') !== false)
   {
      return false;
   }
   return true;
});

Answer 4

From PHP8, you can make calls of str_contain() inside array_filter() and invert its boolean return value.

Code: ( Demo )

$array = ['news', 'artical', '?mailchimp=1'];

var_export(
    array_filter(
        $array,
        fn($v) => !str_contains($v, '?')
    )
);

The above will keep the original keys, so if you need to guarantee that your result array is indexed, just call array_values() .
