Get value from string and put in array

Question

I have a string, for example:

<script language="javascript" src="http://track.adform.net/adfscript/?bn=2827619"></script>
<noscript>
<a href="http://track.adform.net/C/?bn=2827619;C=0" target="_blank">
<img src="http://track.adform.net/adfserve/?bn=2827619;srctype=4;ord=[timestamp]" border="0" width="728" height="90" alt=""/>
</a>
</noscript>

<script language="javascript" src="http://track.adform.net/adfscript/?bn=2826814"></script>
<noscript>
<a href="http://track.adform.net/C/?bn=2827619;C=0" target="_blank">
<img src="http://track.adform.net/adfserve/?bn=2827619;srctype=4;ord=[timestamp]" border="0" width="728" height="90" alt=""/>
</a>
</noscript>

Now i want to get bn=numbers in an array. But only one from each script. Not duplicate. And i wait the size of each banner in same array. Anyone know how to do?

what is the workflow, and my apologies for SO contributors, but what have you tried?! — mamdouh alramadan

Which bn do you want to find? Because the ones in the <a> and <img> tags are all duplicates in this case, so you want to get them from the srcs of the script tags? — rolfv1

rolfv1: I want the bn from the src in javascript code. bn=2826814 and bn=2826819 — Andreas

Here's one way to do it:

Use a DOM Parser to get the elements inside the <script> tag
Use $dom->getElementsByTagName() and retrieve all the <a> tags
Use $elem->getAttribute() to get the href value
Use string functions like explode() or a regular expression to extract the values you need
Use str_split() or preg_split() to split the numbers and store them in an array
