php problem with strings

Hello

I have this problem

varialble $list contains this

Code:

<tr> <td><FONT COLOR="#336699"><B><b>anonymous@host2.com</b></font></b></td>

<td><a href="editquota.html?acct=ftp"><img src="/frontend/test/images/quota.jpg" border=0></a></td><td colspan=2><img src="/frontend/test/images/mainacct.jpg"></td>

</tr>





<tr> <td><FONT COLOR="#336699"><B><b>ftp3@host1.com</b></font></b></td>

<td><a href="editquota.html?acct=ftp"><img src="/frontend/test/images/quota.jpg" border=0></a></td><td colspan=2><img src="/frontend/test/images/mainacct.jpg"></td>

</tr>



<tr> <td><FONT COLOR="#336699"><B><b>ftp2@host2.com</b></font></b></td>

<td><a href="editquota.html?acct=ftp"><img src="/frontend/test/images/quota.jpg" border=0></a></td><td colspan=2><img src="/frontend/test/images/mainacct.jpg"></td>

</tr>



<tr> <td><FONT COLOR="#336699"><B><b>ftp1@host1.com</b></font></b></td>

<td><a href="editquota.html?acct=ftp"><img src="/frontend/test/images/quota.jpg" border=0></a></td><td colspan=2><img src="/frontend/test/images/mainacct.jpg"></td>

</tr>

Before echo $list , I wish to remove from $list all table rows (from <tr> to </tr>) which contain "host2.com" . How to do that ? I tried using preg_match or preg_match_all but I am not able to find a solution .

Any help please ?
Thank you

I found solution

Code:

$parts = explode("</tr>", $list); 

$alfa1= count ($parts);

$alfa1=$alfa1-1;



for($i = 0; $i < $alfa1; $i++) {

if (!ereg ("host2.com", $parts[$i]) )

        

  { 

    echo $parts[$i] . '</tr>'; 

  } 

}

How about something like

Code:

echo preg_replace('|<tr>.*?host2\.com.*?</tr>|', '', $list);

your code doesn't work ... I don't know why but I had same problem using preg_match and preg_match all

perhaps because pregmatch checks only on a single line , but I am not sure .

Oh yeah, I forgot; you should put in some flags (specifically the "s" flag allows the dot to match newlines):

Code:

echo preg_replace('|<tr>.*?host2\.com.*?</tr>|ms', '', $list);

i didn't know the s flaf , thank you.

Where can I read on php manual about these flags ?
