replace numbers problem

[nicob]

Hello,

 

I have something like this

str_replace("\n<font style=\x22font-size: ??px;\x22><a href=\x22http://www.domain.com/search.php?query=\x22></a></font></br> ", "", etc...

 

The problem is that I don't know wich number '??' will be. But I know it has 2 digits. Now How can I tell PHP to replace the whole sentence even I don't know the numbers???

Regex.

 

echo preg_replace("/\d\dpx/", '[bOOM!]', "\n<font style=\x22font-size: 16px;\x22><a href=\x22http://www.domain.com/search.php?query=\x22></a></font></br>");

Thanks for you answer, but I could not find a solution yet. I have tried other regex solutions, but it's not easy.

 

My script must do this:

 

I have a file with search actions from users. It collects information in this format, and it's for my eyes only,

<font style="font-size: 20px;"><a href="http://www.domain.com/search.php?query=keyword">keyword</a></font></br> 
<font style="font-size: 17px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 
<font style="font-size: 17px;"><a href="http://www.domain.com/search.php?query=keyword">keyword</a></font></br> 
<font style="font-size: 20px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 
<font style="font-size: 16px;"><a href="http://www.domain.com/search.php?query=keyword">keyword</a></font></br> 
<font style="font-size: 30px;"><a href="http://www.domain.com/search.php?query=keyword">keyword</a></font></br> 
<font style="font-size: 14px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 
<font style="font-size: 10px;"><a href="http://www.domain.com/search.php?query=keyword">keyword</a></font></br> 
<font style="font-size: 28px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 

 

You see that some lines contain incomplete information. So I have another script that filter those lines out (and also the duplicates), so I won't see empty lines in my html file. BUT the problem is that I use different font size, and I hope there is a easy way to tell php to just ignore those two digits (it's a number between 15-30) and find the dups and empty lines.

 

Example of my code,

<?php
$page = "/home/website/domains/domain.com/public_html/outputdata.txt";
$nodups = array_unique (explode ("\n", str_replace("\n<font style=\x22font-size: 15px;\x22><a href=\x22http://www.domain.com/search.php?query=\x22></a></font></br> ", "", file_get_contents($page))));
echo implode("\n",array_slice($nodups,-101,100));
?>

 

You see '15' (px), but that 15 could also be '28'...

 

Anyone with a tip? thanks!

try

<?php
$page = '<font style="font-size: 20px;"><a href="http://www.domain.com/search.php?query=keyword">keyword</a></font></br> 
<font style="font-size: 17px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 
<font style="font-size: 17px;"><a href="http://www.domain.com/search.php?query=keyword">keyword</a></font></br> 
<font style="font-size: 20px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 
<font style="font-size: 16px;"><a href="http://www.domain.com/search.php?query=keyword">keyword</a></font></br> 
<font style="font-size: 30px;"><a href="http://www.domain.com/search.php?query=keyword">keyword</a></font></br> 
<font style="font-size: 14px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 
<font style="font-size: 10px;"><a href="http://www.domain.com/search.php?query=keyword">keyword</a></font></br> 
<font style="font-size: 28px;"><a href="http://www.domain.com/search.php?query="></a></font></br> ';
$nodups = array_unique (explode ("\n", preg_replace("/\d\dpx/", "20px", $page)));
echo implode("\n",array_slice($nodups,-101,100));
?>

@Sasa

I have tried your code out, and it changes all font size to '20'. But I want to keep the different sizes...

 

Your code helped me to make the next one

<?php
$page = "/home/website/domains/domain.com/public_html/outputdata.txt";
$nodups = array_unique (explode ("\n", str_replace("\n<font style=\x22font-size: ".preg_match('/\d\dpx/', '')."px;\x22><a href=\x22http://www.domain.com/search.php?query=\x22></a></font></br> ", "", file_get_contents($page))));
echo implode("\n",array_slice($nodups,-101,100));
?>

 

Now I don't see the lines without a keyword. example before:

<font style="font-size: 20px;"><a href="http://www.domain.com/search.php?query=car">car</a></font></br> 
<font style="font-size: 17px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 
<font style="font-size: 17px;"><a href="http://www.domain.com/search.php?query=boat">boat</a></font></br> 
<font style="font-size: 20px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 
<font style="font-size: 16px;"><a href="http://www.domain.com/search.php?query=php+freaks">php freaks</a></font></br> 
<font style="font-size: 30px;"><a href="http://www.domain.com/search.php?query=house+for+sale">house for sale</a></font></br> 
<font style="font-size: 14px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 
<font style="font-size: 22px;"><a href="http://www.domain.com/search.php?query=boat">boat</a></font></br> 
<font style="font-size: 10px;"><a href="http://www.domain.com/search.php?query=games">games</a></font></br> 
<font style="font-size: 28px;"><a href="http://www.domain.com/search.php?query="></a></font></br> 
<font style="font-size: 14px;"><a href="http://www.domain.com/search.php?query=car">car</a></font></br>

 

example after the last change:

<font style="font-size: 20px;"><a href="http://www.domain.com/search.php?query=car">car</a></font></br> 
<font style="font-size: 17px;"><a href="http://www.domain.com/search.php?query=boat">boat</a></font></br> 
<font style="font-size: 16px;"><a href="http://www.domain.com/search.php?query=php+freaks">php freaks</a></font></br> 
<font style="font-size: 30px;"><a href="http://www.domain.com/search.php?query=house+for+sale">house for sale</a></font></br> 
<font style="font-size: 22px;"><a href="http://www.domain.com/search.php?query=boat">boat</a></font></br> 
<font style="font-size: 10px;"><a href="http://www.domain.com/search.php?query=games">games</a></font></br> 
<font style="font-size: 14px;"><a href="http://www.domain.com/search.php?query=car">car</a></font></br>

 

Like you see I still have dups in the file: 'car' and 'boat'. This is because of the different font size, and that makes it not a dupe. I'm not a php expert, but I'm trying to discover the power of php. I'm still impressed, and I believe this is possible!
