Replacing Some Array Values

Question

I want to change the 'S' from the array into 'l'. but it won't work. Please help me with this one.

Here's my code:

<?php
    $array = array (
        "romeo/echo/julion/1991s/1992.jpg",
        "romeo/echo/julion/1257s/1258.jpg",
        "romeo/echo/julion/1996s/1965.jpg",
    );
    foreach($array as $key => $value){
        if($key == "romeo/echo/julion/'.*?'s/'.*?'.jpg") $value="romeo/echo/julion/'.*?'l/'.*?'.jpg";
    }
    print_r($value);
?>

str_replace function.

1. You need to use str_replace() along with call by reference

foreach ($array as &$value) {
  $value = str_replace('s/','l/',$value);
}

print_r($array);

Output:- https://eval.in/981246

2. Or you can directly go to array_map()

<?php
function strReplace($n)
{
    return(str_replace('s/','l/',$n));
}

$array = array ("romeo/echo/julion/1991s/1992.jpg",
                "romeo/echo/julion/1257s/1258.jpg",
                "romeo/echo/julion/1996s/1965.jpg",
);
$final_array = array_map("strReplace", $array);
print_r($final_array);
?>

Output:- https://eval.in/981225

3 Or go with preg_replace()

$array = preg_replace('/(\d{4})(s\/)/', '$1l/', $array);

@RheyzaVirgiawanD'first you can ask a new question anytime. But try to clarify your question clearly that what exactly you want and what isn't working? Also, don't forget to post your code effort too. Thanks

You can try like this way,

$array = array ("romeo/echo/julion/1991s/1992.jpg",
                "romeo/echo/julion/1257s/1258.jpg",
                "romeo/echo/julion/1996s/1965.jpg",
);


$array = preg_replace("/(s)(?=\/)/", "l", $array);
print '<pre>';
print_r($array);
print '</pre>';

Output:

Array
(
    [0] => romeo/echo/julion/1991l/1992.jpg
    [1] => romeo/echo/julion/1257l/1258.jpg
    [2] => romeo/echo/julion/1996l/1965.jpg
)

$array = [
    "romeo/echo/julion/1991s/1992.jpg",
    "romeo/echo/julion/1257s/1258.jpg",
    "romeo/echo/julion/1996s/1965.jpg",
];

$array = preg_replace('/(\d{4})(s)/', '$1l', $array);

Result:

array(3) {
    [0] =>
    string(32) "romeo/echo/julion/1991l/1992.jpg"
    [1] =>
    string(32) "romeo/echo/julion/1257l/1258.jpg"
    [2] =>
    string(32) "romeo/echo/julion/1996l/1965.jpg"
}
