Best Way to manipulate a text file.. php ?

8rucech85 · 01-29-2008, 08:24 AM

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

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>";
?>
