How to overwrite line in file without deleting other contents

Sample contacts.txt file:

doe, john, 123
smith, jane, 456
etc
etc
etc

If I want to overwrite smith, jane, 456 with cooper, jones, 678 with $handle = fopen("contacts.txt", "w");

How come it removes all the lines before and after smith, jane, 456

fopen() may not be the best choice, especially with w:

'w' Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

For reasonably sized files this should do it:

$data = file_get_contents('contacts.txt');
$data = str_replace('smith, jane, 456', 'cooper, jones, 678', $data);
file_put_contents('contacts.txt', $data, LOCK_EX);
