How can PHP be used to search for and replace specific content within multiple files in a folder?

To search for and replace specific content within multiple files in a folder using PHP, you can iterate through each file in the folder, read its contents, perform the search and replace operation, and then write the updated content back to the file. 

<?php
$folder = 'path/to/folder';
$search = 'old_content';
$replace = 'new_content';

$files = glob($folder . '/*');
foreach ($files as $file) {
    $content = file_get_contents($file);
    $updated_content = str_replace($search, $replace, $content);
    file_put_contents($file, $updated_content);
}
?>
