Hey i m a newbie, and i am trying to run a php script with my macromedia flash program.
what i want the php to do is to look up for a word in an html file.
the word is: Gateway
in the html code it is writeen like this:
Gateway ***.***.**.**
the part with * the IP of the client. so it change quite often.
In the source of the html code it is written like this:
<TD ALIGN=RIGHT><B>Gateway</B></TD>
<TD>210.9.141.233</TD>
so i wanted the php to look up for the word Gateway, and execute the line.

then u must know how to strip off HTML tags. try regular expressions...

a simple one being:
$str="<td><b>asdasd</b></td>";
$str=preg_replace("/<[^>]*>.*</[^>]>/U","",$str);
echo $str;

Known is handfull, Unknown is worldfull

There is also a PHP function called strip_tags:

Thanks for your replies

But i still can't make it.
what i did, is:

<?php
$url = "

http://192.168.0.1";

$sourcepage = "$url/status.htm";
$handle = fopen("$sourcepage", 'r');
$str=preg_replace("/<[^>]*>.*</[^>]>/U","", $handle);
echo $str;
?>

i also tried the fseek() but i had some error

thanks in advance

I'm STILL stuck!!

<?PHP
$fd=fopen("

http://address/status.htm","r");

while ($line=fgets($fd,6000))
{ $alltext.=$line; }
fclose ($fd);
preg_match ('/(Gateway)(\w+)(</TD>)/i', $alltext, $results);
print $results
?>

I still cannot print out only the ip...
thanks in advance

Your code may have multiple problems.

First, I'd recommend that you strip all inputs from the returns at the ends of lines.

Second, I don't understand what you're trying to match with that regular expression.

Given the following HTML output:

Code:

<html><body><table><tr>
<TD ALIGN=RIGHT><B>Gateway</B></TD>
<TD>210.9.141.233</TD>
</tr></table></body></html>

The following script:

Code:

<?PHP
$fd=fopen(&quot;[URL unfurl="true"]http://server/file.htm&quot;,&quot;r&quot;);[/URL]
while ($line=fgets($fd,6000))
{
	$alltext .= rtrim($line);
}
fclose ($fd);

preg_match ('/(Gateway)<\/B><\/TD><TD>(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/i', $alltext, $results);

print_r($results);
?>

Seems to match what you're looking for. It's output is:

Code:

Array
(
    [0] => Gateway</B></TD><TD>210.9.141.233
    [1] => Gateway
    [2] => 210.9.141.233
)

hi, i seem to have made a mistake:
now does it work?
$str=preg_replace("/<[^>]*>.*</[^>]*>/U","", $handle);

Known is handfull, Unknown is worldfull
