parse contents of file

[ucbones]

Hi,

Another question, I am attempting to take an HTML file, and read the unique contents of the page into the variable $realcontent. The real content is separated by HTML comments, should be fairly obvious. I'm replacing these comments with ¬search¬, and this works fine (on the assumption that none of my site users will write ¬search¬). However, $bufexplode[1] returns empty, any ideas?

The problem appears to be in the the $bufexplode line, as the rest is outputting as predicted.

	if( !($fd = fopen($url,"r")) )
	   die( "Could not open URL!" );
	while( $buf = fgets($fd,1024) ){
		/* Remove whitespace from beginning and end of string: */
		$buf = trim($buf);
		$buf=str_replace("<!-- real content goes here -->", "¬search¬", $buf);
		$buf=str_replace("<!-- end main content -->", "¬search¬", $buf);
		$bufexplode=explode("¬search¬", $buf);
		$realcontent=$bufexplode[1];
		echo $realcontent;
	}
	fclose($fd);

I'm not sure exactly what you are trying to do, you weren't clear enough for me in your post. However, if you are trying to parse a php/html file into a variable without displaying it, an easy way is to use the ob_ functions.

For example:

ob_start ();
do whatever.

$variable = ob_get_contents();
ob_end_clean ();

Once again, I fixed my problem, thanks for the idea though acidbox... Basically all I wanted to do was to put the code between two comments in an HTML file into the variable $realcontents, here's the code that did it...

$buf=implode ('', file ($url));
	$buf = trim($buf);
	$buf = addslashes($buf);
	$contentstart=strpos($buf, "<!-- real content goes here -->")+strlen("<!-- real content goes here -->");
	if ($contentstart === false) {
	   echo "not found";
	exit;
	}
	$contentend=strpos($buf, "<!-- end main content -->");
	if ($contentend === false) {
	   echo "not found";
	exit;
	}
	$contentlength=$contentend-$contentstart;
	$realcontent=substr($buf,$contentstart,$contentlength);
