How to implement batch file content replacement using P…

To achieve batch replacing of file contents in PHP, follow these steps:

1. list the contents of a directory

$dir = 'path/to/files';
$files = scandir($dir);

1. Read the contents of a file
2. replace()

foreach ($files as $file) {
  if ($file !== '.' && $file !== '..') {
    $fileContent = file_get_contents($dir . '/' . $file);
    $newContent = str_replace('search', 'replace', $fileContent);
    file_put_contents($dir . '/' . $file, $newContent);
  }
}

In the code above, “search” represents the content to be replaced, while “replace” represents the content to replace it with.

1. After the replacement is completed, the file content has been replaced in bulk.

Please be aware that in actual usage, it is important to consider the permissions of files in order to ensure the ability to read and write to them. Furthermore, further optimization and judgement can be made based on actual needs, such as only replacing files of specific types, or deciding whether to replace them based on the content of the files.
