I want this script to instead of saying you're a guest, into deleting a line in a TXT file.
Is this possible?
Below is the script I'm using.
if(stripos(file_get_contents('http://www.othersite.com/page.html'), '<script')!== false)
echo('YES');
else
echo('NO')
also is it possible to "search" for a tag or something in the text code and delete it?
What does the text file look like? This is very possible but we need a little more information.
something like
<a href="http://www.google.com">
Google Search Engine </a>
<BR>
Description: A really famous search engine. If you dont know what this is... well.. eh..... um.... crawl under a rock.
Is that all on one line? If not what line do you want deleted?
yeah, if its possible to be deleted...
I'm still not quite clear on what the file looks like. Could you provide an example with more than one? Also please make use of the code tags.
i just want to delete, say 4-5 lines of HTML code.
such as:
Code:<B>code</B>here....<BR>random html code.
What distinguishes the lines you want to keep from the lines you want removed.
erm.. can u show me some code of how to do it, and ill figure a way to do that. :)
Ok,Here is a quick 'n dirty example.
list.txt looks like this
and index.php looks like thisCode:http://www.dynamicdrive.com
http://www.digg.com
http://www.yahoo.com
http://www.google.com
http://www.ebay.com
They both need to be in the same directory. Go ahead and run to see what it doesPHP Code:<html>
<head>
</head>
<body>
<ul>
<?php
if(!empty($_GET['line'])){
$file = file('list.txt');
ob_start();
for($i=0;$i < count($file);$i++){
if(rtrim($file[$i]) != $_GET['line']){
echo $file[$i];
}
}
$write = ob_get_contents();
ob_end_clean();
$handle = fopen('list.txt','w');
fwrite($handle,$write);
fclose($handle);
}
$file = file('list.txt');
for($i=0;$i<count($file);$i++){
echo '<li><a href="index.php?line='.urlencode(rtrim($file[$i])).'">Delete '.rtrim($file[$i]).'</a></li>'."\n";
}
?>
</ul>
</body>
</html>
thanks, but can u help me 'automatically' do it and somehow use preg_replace or str_replace?
'automatically' based on what?
acutrally..
when a website is visited, then it will delete text.
Ok, I see the connection now. That is code I gave you before right? Not sure how to test this so...it is untested
PHP Code:<html>
<head>
</head>
<body>
<?php
$affiliate = 'somesite.com'; //Don't add anything that isn't ALWAYS in the URL
if(strpos(strtolower($_SERVER['HTTP_REFERER']),$affiliate) !== false){
$add = $affiliate;
}
else{
$del = $affiliate;
}
if(!empty($del)){
$file = file('list.txt');
ob_start();
for($i=0;$i < count($file);$i++){
if(rtrim($file[$i]) != $del){
echo $file[$i];
}
}
$write = ob_get_contents();
ob_end_clean();
$handle = fopen('list.txt','w');
fwrite($handle,$write);
fclose($handle);
}
else if(!empty($add)){
$handle = fopen('list.txt','a');
fwrite($handle,$add."\n");
fclose($handle);
}
?>
</body>
</html>
Ok, yeah list.txt needs to look like this
Code:dynamicdrive.com
digg.com
yahoo.com
google.com
ebay.com
what will this delete? Only the url, right?
i want it to delete some text after the url. hope im not bothering you with all my questions

Here I've written a function to do what you want. I'll leave it up to you to determine how to use it.PHP Code:<?php
function deleteline($del,$filename){
$file = file($filename);
ob_start();
for($i=0;$i < count($file);$i++){
if(strpos($file[$i],$del) === FALSE){
echo $file[$i];
}
}
$write = ob_get_contents();
ob_end_clean();
$handle = fopen('list.txt','w');
fwrite($handle,$write);
fclose($handle);
}
//Pass in the search term, then the filename
deleteline('google','list.txt');
?>
thanks, oh grand PHP coder.
this will delete every line that has the word google in it, right?
correct. Be careful this is case-sensitive. google is not the same as GooGLE
thanks blm, :) i know it wasnt easy.
quick question, what does /n do?
/n is the newline character. It is mentioned briefly in the manual here
