PHP在多维数组中搜索。 不懂钥匙

Question

Array:

$userdb = array(
    array(
        'uid' => '100',
        'name' => 'Sandra Shush',
        'pic_square' => 'abc.jpg'
    ),
    array(
        'uid' => '5465',
        'name' => 'Stefanie Mcmohn',
        'pic_square' => 'Michael.jpg'
    ),
    array(
        'uid' => '40489',
        'name' => 'Michael',
        'pic_square' => 'xyz.jpg'
    )
);

Search value:

Michael

Expected output:

$userdb = array(
    array(
        'uid' => '5465',
        'name' => 'Stefanie Mcmohn',
        'pic_square' => 'Michael.jpg'
    ),
    array(
        'uid' => '40489',
        'name' => 'Michael',
        'pic_square' => 'xyz.jpg'
    )
);

As you can check what I want can anyone please tell me How can I achieve this result by using PHP. I don't care whether my search term is in 'uid', 'name', or 'pic_square' key but I want to get array whenever my search term result is matching. Is there any inbuilt function which can achieve this result?

Answer 1

Very simple solution is to apply simple foreach() with strpos()

1.iterate over the array using foreach()

2.Check that search value exist in any one of three id, name,pic_square or not? if yes then add that whole sub-array to a new array.

3.This new array is your desired result.

$search_value = 'Michael';


$final_array = [];

foreach($userdb as $userd){
  if(strpos($userd['uid'],$search_value)!== false || strpos($userd['name'],$search_value)!== false || strpos($userd['pic_square'],$search_value)!== false){

     $final_array[] = $userd;
  }

}

print_r($final_array);
