how to use strpos

[rayzun]

Can someone tell me if Im way off or even close...

I currently have a script to show a webpage Ive got hosted on another server, also I got the script to start and stop displaying HTML at two points.

My question would be can I still go through the $contents and remove HTML from set start and stop points.

$start="<!-- starts";

$end="ends here.";

$url1 = "$myurl";

$fh = fopen($url1,"r");
$contents = "";
do {
$data = fread($fh, 8192);
if (strlen($data) == 0) {
break;
}
$contents .= $data;
} while(true);
fclose($fh);
$start_position=strpos($contents, $start);
$end_position=strpos($contents, $end)+strlen($end);
$length=$end_position-$start_position;
$contents=substr($contents, $start_position, $length);

echo "$contents";

A form is not needed and can be stripped.
Where would this horrible script effort be made into the above very nice script?

$startform="<form";

$endform="</form>";

$contents=strpos($contents, $startform);
$end_position=strpos($contents, $endform)+strlen($endform);

$length=$end_position-$start_position;
$contents=substr($contents, $start_position, $length);

You're in good shape, except you made a typo:

$contents=strpos($contents, $startform);

should be:

$start_position = strpos($contents, $startform);

Please explain my mistake if anyone can tell me more

list($first,$last) = explode('/', substr($PATH_INFO,1));
$start="starts here";

$end="ends here";

<-- Sextra -->
$startform="<SELECT NAME";
$endform="</SELECT>";
<-- Eextra -->

$url1 = "$myurl";

$fh = fopen($url1,"r");
$contents = "";
do {
$data = fread($fh, 8192);
if (strlen($data) == 0) {
break;
}
$contents .= $data;
} while(true);
fclose($fh);

$start_position=strpos($contents, $start);
$end_position=strpos($contents, $end)+strlen($end);
$length=$end_position-$start_position;
$contents=substr($contents, $start_position, $length);

<-- Sextra -->
$start_position = strpos($contents, $startform);
$end_position=strpos($contents, $endform)+strlen($endform);
$length=$end_position-$start_position;
$contents=substr($contents, $start_position, $length);
<-- Eextra -->
echo "$contents";

I like this script, the additional script parts added by me for this post..
<-- Sextra -->
<-- Eextra -->
if taken out will allow this script to function nice.

I don't know what this statement is supposed to do:

while(true); 

but what it does is execute itself over and over. And over and over. The script never gets past that point. Boolean true is always true.

Edit: "...the above very nice script?" How nice could it be? It wouldn't work with that line in it.
