Remove specific value from array using php?

This post shows the possible ways to remove specific element from array based on value of the element.

Removing specific value Using array_diff()

Using this method we can remove one or more elements where using other methods we can only remove/delete one element at a given instance.

function remove_element($array,$value) {   return array_diff($array, (is_array($value) ? $value : array($value))); }   $myArray = array('php', 'laravel', '.net', 'java', 'c#', 'javascript');   $result = remove_element($myArray,'.net');   print_r($result);   // output : Array ( [0] => php [1] => laravel [3] => java [4] => c# [5] => javascript )

Removing specific value using array_search()

Using this method we can only remove one element at given instance. If there are two values with the same text it will remove first element only.

function remove_element(&$array,$value) { if(($key = array_search($value,$array)) !== false) {        unset($array[$key]);   }     }   $myArray = array('php', 'laravel', '.net', 'java', 'c#', 'javascript'); remove_element($myArray,'php'); print_r($myArray);

Removing specific value using array_keys()

If there can be multiple items with the same value, you can use array_keys to get the keys to all items as shown below.

function remove_element($array,$value) { foreach (array_keys($array, $value) as $key) {     unset($array[$key]); }     return $array; }   $myArray = array('php', 'laravel', '.net', 'java', 'c#', 'javascript','php'); $result = remove_element($myArray,'php'); print_r($result);   // output : Array ( [1] => laravel [2] => .net [3] => java [4] => c# [5] => javascript )
