I have a bash script that I want to convert into a PHP script so I can use it on a webpage. Even though the script is very simple, I have no experience in PHP really so I'm confused how to go about this. Here is an example of something I'm having problems with. This is a bash snippit:
MyVariable=`grep -o 'text1>[0-9]+' foo.html
| sed -e 's@^.*>@@g'`All I'm doing there is grepping a text/html file for some specific content, and then filtering it to get just the integer substring. I'm guessing I need to use the string replace function, but I'm not sure how to go about it. Can someone help me out in converting this to PHP code?

Can you give an example of the whole string you want to get info from (the foo.html in this example)
I guess you can make a simple pattern for preg_match
All you got to do, is tell the story right...

foo.html is a webpage I scraped. Here is a chunk of it, within which I want to search:
</td></tr></table><td class=darkbg width=50%><tr><td class=lightbg width=50%><td width=740 class=lightbg nowrap><table border=0 width=100% cellspacing=1 cellpadding=5><tr><td class=lightbg colspan=2><div id=stats><table border=0 width=100% cellpadding=0 cellspacing=6><td width=50% valign=top align=right class=lightbg>a 26 year-old single guy<br><b><a href="http://www.stumbleupon.com/city/hamilton/"><b>Hamilton</b></a>, <a href="http://www.stumbleupon.com/state/ontario/"><b>Ontario</b></a>, <a href="http://www.stumbleupon.com/country/canada/"><b>Canada</b></a></b><br><br><span class=mini>Data about me.</span><td align=center valign=top class=lightbg nowrap=true><a href="/about/"><img border=0 hspace=3 alt="FJ" src="http://www.stumbleupon.com/mediumpics/232345.jpg"></a><td width=50% valign=top class=lightbg>Active <span class=text1>Feb 17</span><span class=mini> · Joined Jan 2/05</span><br><img src="http://www.stumbleupon.com/images/thumbup.gif">'s: <span class=text1>517</span> · Fans: <span class=text1><b>44</b></span> <img src="http://www.stumbleupon.com/images/arank4.gif"></table>The substring I want from the above is 517, to be turned into an integer. Thanks for any guidance you can give me.

if there is only one match per string, you could use this:
<?php
// Get the file contents
$contents = file_get_contents('foo.html');
// Get the matches
preg_match('#text1>(d+)<#', $contents, $matches);
print $matches[1]; // The match
?>If there are more matches per string, you could use preg_match_all, the matches will be $matches[1][0], $matches[1][1] etc etc
Good luck

Thanks for your help! I'll try this out when I get a chance. It looks to be exactly what I need.
