unset array in foreach php

July 20, 2022

i have data array this :

Array
(
    [0] => Array
        (
            [id] => 0
            [id_barang] => 0
        )

    [1] => Array
        (
            [id] => 231
            [id_barang] => 18572679-2.2.2.3
        )
)

here I am looping an array, and I want to delete the array which has id = 0

previously I created two foreach , the first to hold the array data , the second foreach to truncate the array if there is id = 0 , the question is can it be in 1 foreach ?

this my code

            $arr = [];
            foreach($tampung as $key=>$value){ 
                $arr[] = $value;
            }

            foreach($arr as $key=>$rows){ // unset array id == 0
                if($rows['id'] == 0) 
                { 
                    unset($arr[$key]); 
                }   
            }

>Solution :

You can use array_filter to get a new array without id=0. For example:

<?php
$orig = [
    ['id'=>0, 'id_barang'=>'0'] ,
    ['id'=>213, 'id_barang'=>'18572679-2.2.2.3'],
    ['id'=>456, 'id_barang'=>'1879-2.2.2.3'],
    ['id'=>0, 'id_barang'=>'0'] ,
];

$new_array = array_filter($orig, function($entry) {return $entry['id'] !== 0;});
print_r($new_array);

Output:

Array
(
    [1] => Array
        (
            [id] => 213
            [id_barang] => 18572679-2.2.2.3
        )

    [2] => Array
        (
            [id] => 456
            [id_barang] => 1879-2.2.2.3
        )

)
