Question

Can someone pls show me how to map this correctly? I am trying to understand how to use php explode() and organizing the values in a way that I can retrieve and print them in some organized matter. For each record I want to put a name=value in a particular bucket. I have (7) max buckets per record. Sometimes I have records that won’t fill each bucket.

(for example record (2) is missing attributes (5,6,7) and record (3) is missing attribute (4)).

1-Column=host1.colo.sub;2-Column=Fri Aug 13;3-Column=db9.nfl.colo2.;4-Column=00:00:03;5-Column=01:55:02;6-Column=87.24 MB;7-Column=Success;
1-Column=host1.colo.sub;2-Column=Fri Aug 13;3-Column=pdb2.colo2.;4-Column=04:00:02;
1-Column=host1.colo.sub;2-Column=Fri Aug 13;3-Column=gl3_lvm;5-Column=04:48:06;6-Column=54.64 MB;7-Column=Success;

So far I wrote this to view my output:

<?php
$InputFile = file("test.txt");
foreach ($InputFile as $line){
    $pieces = explode(";", $line);
         //print $pieces[0];
         //print $pieces[1];
         //print $pieces[2];
         print $pieces[3];
         //print $pieces[4];
         //print $pieces[5];
         //print $pieces[6];
//print_r($line);
}
?>

I would like to print out similar values for each attribute instead of this where its mixed.
Using ‘print $pieces[3];’

Answer 1

$InputFile = file("test.txt");
foreach ($InputFile as $line){
  preg_match('~(1-Column[^;]*;?)?(2-Column[^;]*)?;?(3-Column[^;]*)?;?(4-Column[^;]*)?;?(5-Column[^;]*)?;?(6-Column[^;]*)?;?(7-Column[^;]*)?;?~',$line,$pieces);
  $pieces = array_pad($pieces,8,'');
  echo "<pre>";print_r($pieces);echo "</pre>";

}

output:
