Split PHP String line-by-line
Usually, you can just
explode("\n"), but some systems use
"\n\r" (actually, I don't think this one is used). So if you're getting documents or text from various systems (as you might on the web), you might want a more robust version than just splitting by
"\n", as you probably don't want extra
"\r" hanging around. I think
"\n" is "new line" and
"\r" is carriage return (i.e. pressing enter), but I'm not sure.
You can also do it with regex, but years ago when I tested, this was signficantly faster.
$arrayOfLines = explode("\n", str_replace(["\r\n","\n\r","\r"],"\n",$str) );
