Search String line-by-line backwards Bottom to Top
<p>I have a file with the following contents. I would like to search string "13030115..." i.e. value before "#". But search should be performed backwards i.e. Bottom to Top. How can I do this in PHP ?</p>

<pre><code>1303011581#user: textMsg
1303011582#user: textMsg
1303011583#user: textMsg
1303011584#user: textMsg
1303011585#user: textMsg
1303011586#user: textMsg
</code></pre>
