PHP - Extract Information From Youtube Into A String

hello,

I want to extract a youtube video variable from users comments, i make a simple function but it works just for one url, if they posted more urls in the same comment, it will return just the first video.

this is what i've done before now:
Code: [Select]
function get_youtube ($youtube){
       $findme   = 'youtube.com/watch?v=';
       $pos = strpos($youtube, $findme);
       if ($pos !== false) {
       parse_str( parse_url( $youtube, PHP_URL_QUERY ));
        echo $v;   
}   
}


How can I make to extract all the $v   from a comment with more url?

thanks

Hello I post this message because I am trying to extract information from a site that has the same system of visacentral, I cannot give access to this system because is in a Intranet, but the system is more or less the same that this site:

visacentral.co.uk/ajax/ajax.visaPopup.php?passport_from=BOL&traveling_to[0]=BHS&traveling_for%5B0%5D=T&traveling_to%5B1%5D=&traveling_for%5B1%5D=&traveling_to%5B2%5D=&traveling_for%5B2%5D=&traveling_to%5B3%5D=&traveling_for%5B3%5D=&account_number=BRITTRAV&account_exists=N

The problem that I have either I use CURL or file_get_contents then they have a redirection and I cannot get the final content from http://visacentral.co.uk/requirements.php

Someone has any idea how this can be done?

Thank you very much!!

I've been trying to get this to work for a few days now and can't seem to get anywhere with it! Any help is very much appreciated.

I am creating a number generator where the user is required to insert the maximum number and generate rate. Maximum number is the highest number that the script will go to, and generate rate is how many numbers should be created.

When the script runs, the numbers are stored into a MySQL database. The MySQL database creates a unique ID number so it can be recalled at a later date.

The user then needs to go to Sorting.php and selects the record they wish to use. The numbers from this record are then counted and then stored into an array.

If the numbers 2,5,5,0,2,2,1,3,5,1 where generated, the output of this new array will be: [5] => 3 [3] => 1 [2] => 3 [1] => 2 => 1  (These arrays can be of any length)

I now need to extract this data and show it on screen. I don't know how to approach it.

Format example:

Number 5 appears 3 times
Number 3 appears 1 times
Number 2 appears 3 times
Number 0 appears 1 times

Sorting.php
<?php
        $db1 = new Number_Information();
        $db1->openDB();

        $sql = "select * from GeneratedNumber";
        $result = $db1->getResult($sql);

        if (!$_POST) { //page loads for the first time
            ?>

            <form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">

                Select the ID (If you have just generated a number, it will be the last one):

                <!--This is the drop down menu-->
                <select name="ID"> 
                    <?php
                    while ($row = mysql_fetch_assoc($result)) {
                        echo "<option value='{$row['ID']}'> {$row['ID']} </option>";
                    }
                    ?>
                </select> <br />

                <input type="submit" value="Continue" />
            </form>

            <?php
        } else {
            $ID = $_POST['ID']; //This will contain the value that was selected in the drop down menu above.

            $result = mysql_query("SELECT NUMBERS2 FROM GeneratedNumber WHERE ID='{$ID}'"); //This tells the script to select NUMBERS2 contents which is assosiated with the ID.

            while ($row = mysql_fetch_array($result))
                $NUMBERS2 = $row['NUMBERS2'];

            echo "$NUMBERS2"; //Testing reasons - remove it later.
            echo "<br />"; //same as above
            echo "$ID"; // as above.
            echo "<br />"; //as above
            //Convert NUMBERS2 back into an array when inserted into table from Generator.php
            $NUMBERS = explode(",", $NUMBERS2);


            // Counts how many times a number appears
            //*******************************************************************************************************************
            //IF ALL ELSE FAILS, REVERT BACK TO THIS.
            //print_r(array_count_values($NUMBERS));
            //It will only print the statement, but gives you a good building block when things WILL go wrong.
            //*******************************************************************************************************************

            rsort($NUMBERS);
            print_r(array_count_values($NUMBERS));

Problem:
"Warning: extract() expects parameter 1 to be array, null given in C:\x\xampp\htdocs\pages\user_personal.php on line 32" - error also found on lines 33 and 38.
and none of the information is displayed.

Goal: I'm trying to retrieve profile information and multiple user inserted pictures and display the pictures through a while loop from one query.

    $result = mysql_query($query, $db) or die(mysql_error());
