Best Way to manipulate a text file.. php ?

I have a tab delimited text file from which i want to compare each successive pair of lines and depending on the result drop one of the lines.

What method would be easiest for this ?

I am running RHE

Example
---------------
a | 10 15
b | 10 13

i want to saw

if col2oflineb > col2oflinea

{
lineb=null;
}

I’m fairly familiar with php but usually doing this with a database not text files...

Any comments would be appreciated

Regards

Bruce

here's an example, rather messy but it is late...

Code:

<?php

$sa = "a        |        10        15";

$sb = "b        |        10        13";



print "a: '".$sa."'<br>";

print "b: '".$sb."'<br>";



print "<br>\n";



$a = split("        ", $sa);

print_r($a);

$b = split("        ", $sb);



print "<br>\n";



print "Therefore:<br>\n";



$sc = ($a[3] > $b[3]) ? ($sa) : ($sb);

print "c: '".$sc."'<br>";

?>
