I have this kind of array:

    Array
(
    [0] => Array
        (
            [title] => Personal
            [closeable] => 1
            [visible] => 1
          )

    [1] => Array
        (
            [title] => My contracts
            [closeable] => 1
            [visible] => 1
        )

    [2] => Array
        (
            [title] => Info
            [closeable] => 1
            [visible] => 1
        )
)

I need to replace one word in the array - My contracts for something else.

My contracts will be always there, but the order may change, so I must check for the exact name and replace it.

I tried it via str_replace($value, $replacement, $array);

also via

$ar = array_replace($ar,
array_fill_keys(
    array_keys($ar, $value),
    $replacement
)

);

and finally:

array_map(function ($v) use ($value, $replacement) {
    return $v == $value ? $replacement : $v;
}, $arr);

Nothing worked. So how can I replace that one word?

Answer 1

foreach ($ar as &$item) {
    if ($item['title'] === 'My contracts') {
        $item['title'] = 'Some new value';
        // if you're sure that record will be met ONCE 
        // you can add `break;` to stop looping
    }
}
