Count New Lines in Text File

问题

I would like to count the number of shift+enters in a text file using PHP.

Please help me with this.

Thanks

回答1:

Assuming you just mean "\r\n" (carriage-return + line feed) by this, the function substr_count in conjunction with file_get_contents should do the trick.

For example:

$count = substr_count(file_get_contents($filename), "\r\n");

You can perform this task by key-events. I think php don't have any key event, so you can use any scripting language like java-script that have key events.
