If you're trying to find lines in a multiline string, you could try
splitting the string on newline characters:

$lines=explode("\n",$progressNote);

Then you can work through $lines looking for relevant ones.

Note that you may have some empty strings in $lines, and also that you
may have \r\n where you expect \n.

A better mechanism may be:

$lines=explode("\n",preg_replace("/[\r\n]+/","\n",$progressNote));

Which will change all instances of any combination of one or more
newlines and / or carriage returns to a single newline, and then split
the string on the newline character.
