How to remove elements or values from an array in PHP

Use the below given steps to remove elements from types of array in PHP:

  • PHP Remove element from array

  • Remove array from multidimensional array PHP

You can use PHP array_pop() function to removes/deletes the last elements of the end of an array.

 $array = array("php", "laravel", "codeigniter");
 array_pop($array);
 
 print_r($array);
?>

  [1] => laravel 
)

Remove key from associative array php

If we want to removes/deletes the elements/values into an array with a key. You can use the below code:

<?php
 
 $array = array("key1" => "value1", "key2" => "value2");

 unset($array['key1']);
 print_r($array);
?>

Output:

)

Here we will remove/delete the elements/values in the array with the key without using array_pop function.

How to remove key from associative array PHP or how to remove the particular key from an array in PHP:

<?php
 
 $array = array("a"=>"red","b"=>"green","c"=>"brown","d"=>"yellow");

Remove array from multidimensional array PHP

If we want to remove/delete values/elements in a multi-dimensional array. Here we will take an example to remove/delete the values/elements in a multidimensional array.

     'web' => ['html', 'css', 'bootstrap'],
     'p_lang' => ['php', 'python', 'cabbage'],
     'framework' => ['laravel', 'codeigniter']
 ];

And you want to remove/delete values/elements inside the array elements. You can use the below example for remove/delete the values/elements in the multidimensional array:

<?php
 
 $array = [
     'web' => ['html', 'css', 'bootstrap'],
     'p_lang' => ['php', 'python', 'cabbage'],
     'framework' => ['laravel', 'codeigniter']
 ];
 
 array_pop($array);
 
 print_r($array);
 
?>

Output:

Array ( [web] => Array ( [0] => html [1] => css [2] => bootstrap ) [p_lang] => Array ( [0] => php [1] => python [2] => cabbage ) )

Remove array inside array PHP with key
