用PHP替换文件中的数组键值

Question

I want to edit values in a array php file.

this is lang.php    
$lang = array (
    'l_name' => "Language",
    'b' => "Break");

I want to replace 'l_name' => "Language", into 'l_name' => "Hi its me.",

how I can do it?

$fileContents = file_get_contents($path_to_file);
$search = array('l_name');
$replace = array('Hi, its me');
$newContents = str_replace($search, $replace, $fileContents);
$handle = fopen($path_to_file ,"w");
fwrite($handle, $newContents);
fclose($handle);

I tried this but its not working its replacing the key 'l_name'

I want to replace to value of key, How can i do it?

Thanks in advance.

Check below code and replace it accordingly.

<?php

//Replace 'l_name' key value:
echo "

Replace 'l_name' key value: 
";
$lang = array (
    'l_name' => "Language",
    'b' => "Break");
$search = $lang['l_name'];
$replace = 'Hi, its me';
$newContents = str_replace($search, $replace, $lang);
print_r($newContents);

//Replace all key value
$newArr = array();
foreach($lang as $key=>$val)
{
  $newArr[$key] = 'Hi, its me';
}

echo "

Replace all key value: 
";
print_r($newArr);

Output

Replace 'l_name' key value: 
Array
(
    [l_name] => Hi, its me
    [b] => Break
)


Replace all key value: 
Array
(
    [l_name] => Hi, its me
    [b] => Hi, its me
)
