String extraction from another string using PHP

Question

I am trying to extract values from XML.My xml file contains a field for product "Description" that consists of Product bardcode, packets and pallets.

I want to extract only Pck (it could be any number from 1-999).

My xml attribute(Description) field values:

  Description="5038135129483  &#xD;&#xAPck: 4   Plt: 120"

Here

 Barcode=5038135129483   
 Number of Packets(Pck)=4
 Number of Palletes(Plt)=120

 $pieces = substr($WhatDescription,19,20);

I have tried substr function to extract from string but it doesn't give me accurate results as the barcode 's length varies and I have got html characters in my XML. Could you advise what shall I do to extract Pck from above string in such away that my extraction wont depend upon html characters and barcode's length.

You should be using an XML parser, not regexes.

You can try:

<?php
   $text = "5038135129483  &#xD;&#xAPck: 4   Plt: 120";
   $newtext = strstr($text,'Pck:');
   echo $final = trim(substr($newtext,0,stripos($newtext,'Plt:')));
?>

You can use strip_tags() and replace   here is example: codepad.org/iuc5piWv
