[RESOLVED] Extracting Text Between Two Strings

[wxgoes1985]

Hi there,

In my attached PHP script, I extract text between two strings in the input file and write the extracted text to an output file. Everything seems to work fine, except I can't figure out how to include the row that says "Richland" (after the row that says "Creighton") in the extracted text.

If someone could guide me how to do this, I'd greatly appreciate it. The PHP script is attached. The input file is in htm format and I can't attach that here so I will provide a link to the file I'm calling: http://www.afws.net/data/pa/savedata/109/06/2009060920.pa.htm

Many thanks!!!

Sticking to your approach, just grab the string index for $start, use that as offset to $stop, and look for "\n" (note that '\n' is not the same thing)

$start='Richland';
$stop="\n";
$startI = strpos($s, $start);
$stopI = strpos($s, $stop, $startI);
$text=substr($s, $startI, $stopI - $startI);

I'd also start checking for $stopI > $startI. If you search for a nonexistent $stop, $stopI will be false, and $stopI - $startI => 0 - $startI => get text from $startI up until $startI characters from the end.

$start='Richland';
$stop="Does not exist";
$startI = strpos($s, $start);
$stopI = strpos($s, $stop, $startI);
if ($stopI > $startI)
	$text=substr($s, $startI, $stopI - $startI);
else 
	$text = '';

Thank you, this guidance worked perfectly!
