Hello everyone i am facing a problem to explode a MwLAI_TXowc a from a specific string,
I want to explode MwLAI_TXowc from following youtube code.
<iframe width="640" height="360" src="https://www.youtube.com/embed/MwLAI_TXowc" frameborder="0" allowfullscreen=""></iframe>
Please help me how to explode MwLAI_TXowc from youtube embed code in php.
Thanks in advance
You dont have to use PHP function explode for this PHP function pathinfo is much easier.
<?php
$url = 'https://www.youtube.com/embed/MwLAI_TXowc';
$basename = pathinfo($url)['basename'];
echo '<pre>';
var_dump($basename);
echo '<pre>';
?>
Output
string(11) "MwLAI_TXowc"
Or if your PHP doesnt support direct array access with functions
<?php
$url = 'https://www.youtube.com/embed/MwLAI_TXowc';
$pathinfo = pathinfo($url);
$basename = $pathinfo['basename'];
echo '<pre>';
var_dump($basename);
echo '<pre>';
?>
Output
string(11) "MwLAI_TXowc"
Use preg_match for your string
$s = '<iframe width="640" height="360" src="https://www.youtube.com/embed/MwLAI_TXowc" frameborder="0" allowfullscreen=""></iframe>';
preg_match('/.*"http.*\/embed\/(.*?)".*/', $s, $matches);
var_dump($matches);

How to make youtube video work on site without embeded code? I mean direct code as: https://www.youtube.com/watch?v=ouDmKW1FGjo. I want the user to paste direct video url into a field VIDEO_LINK not the embeded code. How can I do that? Only embeded link works on the below code not the direct link.
<iframe width="100%" height="550" src="<?php the_field('video_link') ?>" frameborder="0" allowfullscreen></iframe>
Use the following code to get video key (assuming the URL is https://www.youtube.com/watch?v=ouDmKW1FGjo):
<?php
$video_url=get_field('video_link');
$url = urldecode(rawurldecode($video_url));
preg_match("/^(?:http(?:s)?:\/\/)?(?:www\.)?(?:m\.)?(?:youtu\.be\/|youtube\.com\/(?:(?:watch)?\?(?:.*&)?v(?:i)?=|(?:embed|v|vi|user)\/))([^\?&\"'>]+)/", $url, $matches);
// Get key of youtube by preg_match and put it in iframe
$videoKey= $matches[1];
?>
<iframe width="100%" height="550" src="https://www.youtube.com/embed/<?php echo $videoKey ;?>" frameborder="0" allowfullscreen></iframe>
You may use this function to convert Youtube URL to embeded code:
function get_youtube_embed($youtube_url, $width=560, $height=315)
{
$height = (int)$height;
$width = (int)$width;
$embed_html = '';
$parts = parse_url($youtube_url);
if(isset($parts['query'])) {
parse_str($parts['query'], $query);
if(isset($query['v'])) {
$embed_html = '<iframe width="'.$width.'" height="'.$height.'" src="https://www.youtube.com/embed/'.$query['v'].'" frameborder="0" allowfullscreen></iframe>';
}
}
return $embed_html;
}
i need some help for get images. Im using preg_match_all function.
Source: <img alt="test" title="test" src="/data/brands/test.png">
how can i get full image url ?
And this is my code for text. I need add image here.
<?
$link = 'link';
$marka = '#<div class="test">(.*?)</div>#si';
$getir = file_get_contents($link);
preg_match_all($marka,$getir,$test1);
$test = $test1[0];
echo $test[0]; ?>
Thanks.
This might help you
$str = '<img alt="test" title="test" src="/data/brands/test.png">';
$regex = '#src="(.+?)">#';
preg_match($regex,$str,$match);
echo $match[1];
//prints: /data/brands/test.png
I'm trying to turn youtube links into embed iframes, to play the videos. However, my current code is replacing the entire sentence with the embed code. What I want to do is to just convert the youtube link to an embed code, and leave the rest of the text unharmed.
Example: This is a youtube link: https://www.youtube.com/watch?v=T-8XurAKMkU and some text after.
Turned into: This is a youtube link: <embed> and some text after.
My current code:
$testing = "This is a youtube link: https://www.youtube.com/watch?v=T-8XurAKMkU and some text after.";
echo $core->convertyoutube($testing);
And the function:
public function convertyoutube($link) {
if (strpos($link, 'youtube.com/watch?v=') == true) {
$url = $link;
parse_str(parse_url($url, PHP_URL_QUERY), $youtube_array);
$videoid = $youtube_array['v'];
$embed = "<iframe width='420' height='315' src='https://www.youtube.com/embed/".$videoid."'></iframe>"; // what it should create with the extracted code
return $embed;
}
}
Well You are returning only embed code:
return $embed;
You need to replace only youtube part:
public function convertyoutube($link) {
$position = strpos($link, 'youtube.com/watch?v=');
if ($position !== false) {
$chunks = explode(' ', $link);
foreach ($chunks as &$chunk) {
$isYoutubeLink = strpos($chunk, 'youtube.com/watch?v=');
if ($isYoutubeLink !== false) {
$url = $chunk;
parse_str(parse_url($url, PHP_URL_QUERY), $youtube_array);
$videoid = $youtube_array['v'];
$chunk = "<iframe width='420' height='315' src='https://www.youtube.com/embed/".$videoid."'></iframe>"; // what it should create with the extracted code
}
}
return implode(' ', $chunks);
}
}
It works with multiple links in sentence. I guess there is "better" way with using regexp, however I am not very good at regexp and don't like to use it where it is not mandatory.
You could actually do this all with a single regex.
echo preg_replace('/https?:\/\/(?:www\.)?youtube\.com\/watch\?v=(.+?)(?:&|\s|$)/',
'<iframe width="420" height="315" src="https://www.youtube.com/embed/$1"></iframe>',
'This is a youtube link: https://www.youtube.com/watch?v=T-8XurAKMkU and some text after.');
Output:
This is a youtube link: https://www.youtube.com/watch?v=T-8XurAKMkU and some text after.

It will be better if you convert the links at the front-end view with javascript to avoid a excess loading of server. But it's your choise.
Single youtube video has different links like these:
1) https://www.youtube.com/watch?v=lfKON5AMvTM
2) https://youtu.be/lfKON5AMvTM
For this reason you should write your codes like this to catch every type of youtube links:
public function convertYouTube($content) {
$content = preg_replace("/http(s)?:\/\/youtu\.be\/([^\40\t\r\n\<]+)/i", '<iframe width="420" height="315" src="https://www.youtube.com/embed/$2"></iframe>', $content);
$content = preg_replace("/http(s)?:\/\/(w{3}\.)?youtube\.com\/watch\/?\?v=([^\40\t\r\n\<]+)/i", '<iframe width="420" height="315" src="https://www.youtube.com/embed/$3"></iframe>', $content);
return $content;
}
Can someone tell me why when I run this code the preg_replace function seems like it does nothing?
<?php
$string = 'waka http://video.webmfiles.org/big-buck-bunny_trailer.webm waka';
$search = '#http\:\/\/.\.webm #';
$replace = '<video width="320" height="240" controls><source src="$1" type="video/webm"></video>';
$url = preg_replace($search,$replace,$string);
echo $url;
?>
Is my $search string wrong? If so, how can I fix it? It's suppose to replace strings starting in http:// and ending in .webm and surround them with the html code needed to play the .webm video.
Here's how I'd do this...
$string = 'waka http://video.webmfiles.org/big-buck-bunny_trailer.webm waka';
$search = '/(https?\:\/\/.+?\.webm)\h/';
$replace = '<video width="320" height="240" controls><source src="$1" type="video/webm"></video> ';
$url = preg_replace($search,$replace,$string);
echo $url;
Output:
waka <video width="320" height="240" controls><source src="http://video.webmfiles.org/big-buck-bunny_trailer.webm" type="video/webm"></video> waka

I ended up figuring it out. I'm now using:
$search = '#http:\/\/([^\']+)\.webm #';
I know i am missing something simple. I just want to display this iframe if $video-code exists. Can anyone see what is wrong with this? working in wordpress. error is on the echo line. i've also tried adding .'$video-code'. into the url.
it is displaying the iframe correctly, but the variable is displaying as text in the url. if i call the variable elsewhere in the page without the If statement, it displays correctly.
THANKS for any help!
<?php
$key = 'video-code';
$themeta = get_post_meta($post->ID, $key, TRUE);
if($themeta != '') {
echo '<iframe id="player" width="560" height="315" frameborder="2" src="http://www.youtube.com/embed/$video-code" ></iframe>';
}?>
You can concatenate your $key, like so:
echo '<iframe id="player" width="560" height="315" frameborder="2"
src="http://www.youtube.com/embed/' . $key . '" ></iframe>';
