PHP Array delete an entire array by one element value - php

Question

So this is how my Array ($dataArray) looks oks like:
Array
(
[0] => Array
(
[0] => Date
[1] => Time
[2] => Duration
[3] => Info
[4] => Client
)
[1] => Array
(
[0] => 2021-12-01
[1] => 10:45:43
[2] => 237
[3] => Some text from
[4] => Client 1
)
[2] => Array
(
[0] => 2021-12-01
[1] => 11:29:13
[2] => 77
[3] => Nothing important
[4] => Client 2
)
[3] => Array
(
[0] => 2021-12-01
[1] => 11:53:03
[2] => 44
[3] => anonymous
[4] => Client 1
)
I need to Loop trough it to search the Client Names, and if i find the matching name in the Element 4 then delete the entire Array.
$ExportKDname = "Client 1"
foreach($dataArray as $key => $sub_array) {
if($sub_array[4] == $ExportKDname) {
unset($dataArray[$key]);
break;
}
}
print_r($dataArray);
But with this code none of the arrays will be deleted. And I just can not find the right way to do it.
The Final array what I need to look like if we find the "Client 1" in the array would be like this:
Array
(
[0] => Array
(
[0] => Date
[1] => Time
[2] => Duration
[3] => Info
[4] => Client
)
[1] => Array
(
[0] => 2021-12-01
[1] => 11:29:13
[2] => 77
[3] => Nothing important
[4] => Client 2
)

Answer 1

In the if condition you are saying "if u match with $sub_arr[4] == $ExportKDname unset it and stop the loop". the machine doing that. when it matched first time it removes and stoping. If u wanna delete all match do not write break; let it continue. So delete or make it comment break; line.

Answer 2

You can array_filter your variable and check if value is in_array.
With PHP 7.4+ syntax it should look like this:
$result = array_filter($dataArray, fn ($innerArray) => !in_array('Client 1', $innerArray));
