Bug description: Garbage being returned when displaying contents of a url
What should happen:
==================
The script is meant to create a printer-friendly version of a ski resort
review page that is produced dynamically. It does this by opening a socket
connection to the url, including the query, and read the contents of that
url line by line looking for <!-- START CONTENTS --> and <!-- END CONTENTS
--> tags. It echoes whatever is between those tags.
What does happen:
================
The script works except for two issues.
1) In between some of the paragraphs of text some garbage hex numbers
appear. They are always in the same place and the first two bytes are
always the same.
2) The script runs extremely slowly which is attributed completely to the
fsockopen() function.
It should be noted that by simply replacing the fsockopen with fopen() the
problems disappeared without any other changes to the code.
Extraction from the Script that fails:
=====================================
<?
<snip>
$fp=fsockopen($myServer,80,&$errno,&$errstr,30);
$request = "GET $document"."?"."$query"." HTTP/1.1\r\n";
$request .= "Host: $myServer\r\n\r\n";
if(!$fp) {
echo "$errstr ($errno)<br>\n";
} else {
fputs($fp,$request);
$content=0;
$in_title=0;
?>
</snip>
<snip>
<?
while(!feof($fp)) {
$line=fgets($fp,4096);
if(ereg($START_CONT,$line)) {
$content=1;
}
if(ereg($END_CONT,$line)) $content=0;
if($content==1)echo $line;
}
fclose($fp);
?>
Extraction from working script:
==============================
<snip>
<?
$fp=fopen($myURL,r); //in place of fsockopen()
// $request lines no longer required, removed.
?>
</snip>
