preg_match

[dprevite]

I am trying to grab a number from a website, the code I am using is this:

preg_match("TD class=s align=left>[0-9] people found",$file,$match); 

and I am getting this error:

 Warning: Delimiter must not be alphanumeric or backslash in c:\inetpub\wwwroot\SMDRscripts\scrapeByPhone.php on line 19

What am I doing wrong? I'm not that great at regular expressions, it's one of those things I've been putting off 🙂

Thanks in advance

preg_match("/TD class=s align=left>[0-9] people found/",$file,$match);

You need to delimit the search pattern using two of the same character, these must be alphanumeric or backslash, convention says use slashes 🙂

If you want you can capture just the bits needed using parentheses:

preg_match("/TD class=s align=left>([0-9]) people found/",$file,$match);

This will match one number between 0 and 9. Assuming that the number could be 10, or 100, you would need

preg_match("/TD class=s align=left>([0-9]+) people found/",$file,$match);

Where + is the regexp operator denoting 'one or more'
