Reading source file

john1704

I want to make this so it reads a source code from the previous page where the user clicked the link. However, the fread function limits to a certain file size, only a puny 8k or something like that. I need it to read a 13.8 MB web page source code, then read a specific line of that code.

How do you fix this, and how do you make it so it reads a specific line, say line 306? Thanks, I appreciate your help.

<?php
$url = $_SERVER["HTTP_REFERER"];
echo "Your are now currently being redirected. Please wait.";
$token = substr($url, "=");
$subject = "Your subject here";
$message = "Your message here";
$handle = @fopen("$url", "rt"); 
$source_code = @fread($handle,30); 
echo "$source_code";
?>

Use [man]file/man to read the file into an array of lines, then it's easy to echo a specific line:

$lines = file('file.txt');
echo $lines[305]; // echo's contents of line 306

There's a problem with that. I get this error message:

Warning: file($handle): failed to open stream: No such file or directory in /home/pwnedbyj/public_html/bulletins/original.php on line 8

Line eight being this:

$source = file('$handle');

I guess it only reads text files created in the directory, not variables like I'm using. If I used the file function, then I would have to make something where it creates the source code text file in the same directory, and all of that junk that I don't want to deal with. If you would like to code that all for me, be my guest, but I'm looking for something simpler, like just using the fread function.

Can you explain to me why fread will only take a certain file size, not unlimited like I want it to?

A few readings about String Types might help u ...

Maybe some Filesystem functions too ...

As bogu points out, variables aren't parsed in single-quoted strings, so $handle is literally a dollar sign followed by the word 'handle'. Then again, I fail to see why so many people use quotes at all when they're just using a variable as an arguement:

$variable = 'HELLO WORLD!';
$variable = ucwords(strtolower($variable));
echo $variable;

Anyway, as bogu also points out, you need to check out the page for [man]file/man as it doesn't take the parameter you're trying to pass to it.

Ok I have a new question. If you're wondering here's what I'm trying to do: create a myspace auto-bulletin poster. To do that, I need to find the hash number and hashcode or else the CFM scripts on myspace won't accept the posted bulletin from my site. What I was trying to do was read the source of the page, and then hopefully pull out the certain hashcode to include in the bulletin form. However, I now learned that using this script:

<?php
$postedurl = $_SERVER["HTTP_REFERER"];
echo "Your are now currently being redirected. Please wait.";
$token = substr($url, "=");
$url = "http://bulletin.myspace.com/index.cfm?fuseaction=bulletin.confirm&Mytoken=$token";
$subject = "Your subject here";
$message = "Your message here";
$finalsource = @file_get_contents($url, 5);
//Begin first hash
$hash = $finalsource[305];;
?>

won't work. When I refer back to the referred URL, myspace doesn't accept it and returns the HTML of the front page, which is not what I want. How would I make it so that PHP reads the cookies I need, and includes them when fetching the page source?

Try using [man]curl[/man] lib ...
