How can you insert a string at a specific position in a file using PHP?

To insert a string at a specific position in a file using PHP, you can read the contents of the file, insert the desired string at the specified position, and then write the updated content back to the file. This can be achieved by using functions like `fopen()`, `fseek()`, `fwrite()`, and `fclose()` in PHP. 

$file = 'example.txt';
$position = 10;
$insertString = "inserted string";

$fileHandle = fopen($file, 'r+');
fseek($fileHandle, $position);
$remainingContent = fread($fileHandle, filesize($file) - $position);
fseek($fileHandle, $position);
fwrite($fileHandle, $insertString . $remainingContent);
fclose($fileHandle);
