PHP - Line Feed, Carrige Return? Configuration Problem?

what im trying to do is take a youtube embed code find the URL code for that video and remove all other parts of the code keeping only the URL of the video
after i get the URL by it self then replace the http://www.youtube.com/ part of the URL with http://i2.ytimg.com/vi/

to do this i know that i need something like this to get the URL of the video
http://www.youtube.com/((?:v|cp)/[A-Za-z0-9\-_=]+)
but how to only return just the URL is something idk how to do

then use str_replace http://www.youtube.com/(?:v|cp)/" with  http://i2.ytimg.com/vi/

so in the end im asking if anyone know how to remove all other codes i dont want  and only keep the URL


this may have to be done using "regex" im not sure as i dont know to much about regex and what it can do but does sound like it would help lol

Hello.
Trying to get rid a line feed which is coming from a excel cell which has Text and a line feed after that word.
After the excel file has been saved-as tab-delimited, that text transforms to this: "Text"
That line feed is between t and the last double-quote. Hex viewer shows: 22 54 65 78 74 0A 22 so it must be that 0A.

I have tried with trim() and with str_replace("\x0A","",$data) but nothing (like \r or \n) works.

How do I get rid of that hidden character? Is that \x0A correct?

Hi there,

 

I am trying to wrap some content in a div, but when I render it, it is outputting the actual HTML.

This is the line I have:

add_filter( 'woocommerce_product_description_heading', 'rename_product_description_heading', 10, 1 );
function rename_product_description_heading( $heading ) {
    return  __( '<div class="myclass">Additional Information</div>', 'woocommerce' );
}

 

which is outputting:

<div class="myclass">Additional Information</div>

rather than wrapping it in the div.

 

Can anyone help me with wrapping the "Additional Information" text in a div?

Thank you :)

I am trying to troubleshoot a problem with a php script that incorporates an RSS feed (with Magpie 0.72.)  I did not code the site, and am trying to retrace the original logic.  Tech support at my web hosting firm said that the problem was in line 4 of INDEX.PHP:
1.   <?php
2.   require ("\\\\(HOSTING SITE NAME)\\config.inc.php");
3.   require ($CONFIG['admin_dir'].'page.class.php');
4.   require ($CONFIG['admin_dir'].'function.inc.php');
5.   $currentFile = $_SERVER["SCRIPT_NAME"];
6.   $parts = explode('/', $currentFile);
7.   $currentFile = $parts[count($parts) - 1];
8.   $currentFile = preg_replace("/\.\w+$/", "", $currentFile);
9.   $page = new page($currentFile, $CONFIG);
10.   if ( !$page->isActive() ) {
a.   $currentFile = $CONFIG['404_page'];
b.   $page = new page($currentFile, $CONFIG);
11.   }
12.   require ($CONFIG['include_dir'].$page->getTemplate().'.php');
13.   ?>

The RSS feed is in an INCLUDES directory that is defined by CONFIG.INC.PHP:

<?php
    # URL to the RSS feed
    // CIO.com
    $FEED_URL = "http://feeds.cio.com/cio/feed/articles?format=rss";
    $NUM_ITEMS = 5;
   
    require($CONFIG['include_dir'].'magpierss-0.72\rss_fetch.inc');
   
    # Fetch the feed
    error_reporting(E_ERROR);
    $rss = fetch_rss($FEED_URL);
    if($rss) {
        # Split array with our amount of items
        $items = array_slice($rss->items, 0, $NUM_ITEMS);
       
        $rssChannelTitle = $rss->channel['title'];
        $rssChannelLink = $rss->channel['link'];
        // $rssChannelDesc = $rss->channel['description'];
        $output = "";
        $output .= "";
        foreach ( $items as $item ) {
            $output .= '<li class="item">';
                $output .= '<a class="itemLink" target="blank" href="';
                    $output .= $item['link'] . '">';
                    $output .= $item['title'];
                $output .= '</a>';
                /* CIO's feed contains ads.
                  $output .= '<p class="description">' . $item['description'] . '</p>';
                 */
            $output .= "</li>";
        }
        $output .= "";
    }
?>
<?php if($rss) { ?>
    <div class="rssFeed <?php echo $rssChannelTitle ?>">
        <h1>
            <a href="<?php echo $rssChannelLink ?>">
                <?php echo $rssChannelTitle ?>
            </a>
        </h1>
        <!-- <h2><?php echo $rssChannelDesc ?></h2> -->
        <ul class="itemList">
            <?php echo $output ?>
        </ul>
    </div>
<?php } ?>

What am I missing?

Greetings.  First time poster looking for some PHP help if it can be provided, because I'm confused as hell.

First off, I'll explain my situation.  I'm the IT technician of a small business tasked with ensuring the business' computers and website are running in top shape.  I originally joined as a Data Entry clerk to post products to the business' website, but got promoted when they original IT technician left town to pursue his PhD.  Before he left, he taught me a few things to prepare watching over the website as my new duty, including some PHP and MySQL.  Now, a few months after he's left, I have the glorious task of trying to move our website to a new host because we've apparently outgrown our original host's capabilities.  And being based on PHP with a MySQL database, it's turning out to be OH-so-fun.

So far, I've managed to download our entire website from the old host and given it to our new host to put up as a testing site, to ensure everything works before we switch hosts.  And for the most part, a lot of it has come together nicely, but there's still work needed to be done.  And thus we come to the problem I hope someone here can help with.

Our website has two back-end Admin sections, an older one that used to handle everything, and a newer one that's sleeker but still reads off a lot of data from the older one to work properly.  Normally, when you access those sections, you need to log in first.  Now, in the testing site, when I access those areas, the header of each of those sections now reads <?= $row[title] ?> and if I attempt to log in as normal, it just flashes back to the login page with the fields now cleared of what I typed in.  When I asked about this to see what the problem might be, the new host said it might "at least two misconfigurations on the new server relative to the old server".  So, I've been trying to Google for some help with PHP Configuration Functions, but I don't know if what I'm reading will help me fix the problem.  Would anyone here happen to know what they might mean in this case, because my knowledge of PHP is fairly limited beyond what I was taught to keep the website in order without considering a host change...

Thanks to those who help or can direct me to a place that helps!
