Note: If someone already has a working version of this script PLEASE direct me to it. I couldn't find one anywhere...

 

Hello anyone! Please help a newbie coder figure out what's going on here...

 

My script first needs the following url parameter to be set: http://script-url-here.com?s=http://url-of-site-to-be-checked-here.com

 

$url = "http://url-of-site-to-be-checked-here.com";

 

Next it reads the entire contents of that url and puts it in a variable

 

$content = file_get_contents($url);

 

After that it finds the total number of '<embed' and '<object' in $content and then uses while loops to find the positions and writes everything out. (see the code below)

 

Here is the entire script:

-It's not working right

-Some kind of infinite loop?

-Complains about line 53 (strpos() Offset not contained in string)

---The error on 53 is probably what is causing it all. I was trying to

<html>
<head><title>Video Embed Code Extractor</title></head>
<body>
<div id='wrapper'>
<?php
$url = $_GET["s"];
if (isset($url)){ //This wraps around the whole code

//A little if statement to add a 'http://' to the url if it is not already there
$urlpos = strpos($url,'http://');
if ($urlpos === false) {
$url= 'http://'.$url;
}else{
// do nothing
}




echo 'The Url You Submitted: '.$url.'<br/>';
// Get url contents
$content = file_get_contents($url);

//Set strings to be searched for later
$embed_begin='<embed';
$embed_end='>';
$object_begin='<object';
$object_end='object>';

// Finds the number of Embed and Object Codes and the total number
$embed_count=substr_count($content,$embed_begin);
$object_count=substr_count($content,$object_begin);
$total_items=$embed_count+$object_count;

If ($total_items==0){
die('Sorry, No Videos found... ');
}else{
?>
You are in luck! We found: <?php if($total_items>1){echo $total_items.' Videos';}else{echo $total_items.' Video';}?><br/>
<?php
//if elseif and else combo to deside what to display
if($embed_count==0){
echo $object_count.' Object Video(s)<br/><br/>';
}elseif($object_count==0){
echo $embed_count.' Embed Video(s)<br/><br/>';
}else{
echo $embed_count.' Embed Video(s) and '.$object_count.' Object Video(s)<br/><br/>';
}
}

// The search for embeds
$embedpos_0=0;
$count1=1;

while (($count1 <= $embed_count)&& ($count1 < 5)) {  // the ($count1 < 5) part was because I kept getting infinite loops...
$embedpos_.$count1 = strpos($content, $embed_begin, $embedpos_.($count1-1));
$embedendpos_.$count1 = strpos($content, $embed_end, $embedpos_.$count1); 
$embedoutput_.$count1 = substr($content, $embedpos_.$count1, ($embedendpos_.$count1-$embedpos_.$count1));
$embedhtml_.$count1 = str_replace("<","<",$embedoutput_.$count1);
$count1++;
echo $count1;
echo $embed_count.' ';
}


// The search for objects
$objectpos_0 = 0;
$count2 = 1;

while (($count2 <= $object_count)&& ($count2 < 5)) {
$objectpos_.$count2 = strpos($content, $object_begin, $objectpos_.($count2-1));
$objectendpos_.$count2 = strpos($content, $object_end, $objectpos_.$count2);
$objectoutput_.$count2 = substr($content, $objectpos_.$count2, ($objectendpos_.$count2-$objectpos_.$count2));
$objecthtml_.$count2 = str_replace("<","<",$objectoutput_.$count2);
$count2++;;
}

/////Begin the writing process

//Embeds First
$count3 = 1;

while (($count3 <= $embed_count)&& ($count3 < 5)) {
?>
<br/><br/>
<form>
<input type="text" size="35" value="<?php echo $embedhtml_.$count3; echo $embed_end; ?>" onClick='highlight(this)'; readonly>
</form>
<br/><br/>
<?php
$count3++;;
}

//Objects Next
$count4 = 1;

while (($count4 <= $object_count)&& ($count4 < 5)) {
echo $objectoutput_.$count4.'>';
?>
<br/><br/>
<form>
<input type="text" size="35" value="<?php echo $objecthtml_.$count4; echo $object_end; ?>" onClick='highlight(this)'; readonly>
</form>
<br/><br/>
<?php

$count4++;
}

?>
<script language="JavaScript">
function highlight(field) {
       field.focus();
       field.select();
}</script>
<?php
}else{ //Ending the isset($url)
die('Please set the url ?s=*entire-url-here*');
}
echo '<br/>';        // Me trying to debug stuff here...
echo $embed_begin.'-1-<br/>';
echo $embed_count.'-2-<br/>';
echo $object_count.'-3-<br/>';
echo $total_items.'-4-<br/>';

?>
</div>
</body>
</html>

 

Any thoughts?

 

Has someone already done this before and I'm waisting my time?

 

Thanks for the help in advance!
