Detecting URL in a text file

  $fp = fopen($_SERVER['DOCUMENT_ROOT'] . '/categories/'.$_GET['category'].'/'.$_GET['subcategory'].'/data.txt', 'w');

  if ($fp === false) die("Couldn't open data.txt for writing!");

  foreach ($domains as $dom => $count) {
	
	  [color=red]if(eregi($dom,$_SERVER['HTTP_HOST'])) {
       //I WANT TO REMOVE THE LINE
		}
    else {[/color]
    fwrite($fp, "$dom $count\n");
		[color=red]}[/color]

  }

  fclose($fp);

Code (markup):

In the above code, I want to remove a line (within data.txt) if it contains the current domain name. I have added the parts in red. What am I doing wrong?

 

Well you can do something to remove the file with unlink() and just recreate the text file.

 

I already have functions to delete and recreate the file. However, when the file is being created, I want to detect if certain lines contain HTTP_HOST and remove those lines.

 

I'm not sure I completely understand what you're trying to do, it sounds like what you want can be accomplished by using file_get_contents to read the file into a string, using eregi_replace, and then writing the string back into the file.

 

try something like this

preg_match("/http(s)?:\/\/(*.?)\s/", $stringUrl, $matches)

PHP:

never mind I had someone help me..

I was on the right track.

To do what I wanted the code is:

if(eregi($_SERVER['HTTP_HOST'], $dom)) {
       echo "";
		}
    else {
    fwrite($fp, "$dom $count\n");
		}

Code (markup):

 

if (!eregi($_SERVER['HTTP_HOST'], $dom))
	fwrite($fp, "$dom $count\n");

PHP:

Should accomplish the same, without the unecessary echo.

 

Do not use regular expressions for these 'small' tasks. Use str_replace() instead. Regex are more resource consuming and powerful, both of which are not needed for your case.

Also, if you insist on regex, then use preg_* functions instead of ereg() functions. Ereg functions have some bugs/flaws.
