Introduction

Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

Requirements

• CentOS 7
• cURL
• PHP (including php-cli)

Installation

The installation process of Composer is relatively simple. First, let's get in the good habit of updating our server.

# sudo yum -y update

Switch into the temp directory.

# cd /tmp

Install Composer using cURL

# sudo curl -sS https://getcomposer.org/installer | php

Want to make Composer globally accessible?

# mv composer.phar /usr/local/bin/composer

Conclusion

Composer is an essential tool for any PHP developer. It is very easy to install and you will save countless hours over the years automating your dependencies. Happy developing!

PHP to check if a URL contains a query string

http://stackoverflow.com/questions/7864237/php-to-check-if-a-url-contains-a-query-string

For any URL as a string:

if (parse_url($url, PHP_URL_QUERY))

http://php.net/parse_url

If it's for the URL of the current request, simply:

if ($_GET)

	thanks for the quick response but I've already tried that. {% set var_html = "[special_tag]"%} {{ var_html|replace({"[special_tag]": "<p>new value</p>" }) }} result: <p>new value</p> expected: new value – karl2108 Apr 23 '14 at 8:58  You'll have to add another filter: raw: {{ var_html | replace(...) | raw }} – Crozin Apr 23 '14 at 9:18 Awesome! thanks! – karl2108 Apr 23 '14 at 23:03

Retrieve video ids from playlist id - youtube api v3

http://stackoverflow.com/questions/26817919/retrieve-video-ids-from-playlist-id-youtube-api-v3

http://www.codeproject.com/Tips/998364/Youtube-video-list-with-PHP

I am currently working with youtube api v3. I am trying to retrieve video ids from a particular playlist. I have search through the documentation but can’t find an example that references that or something similar. I am using this repo from GITHUB. How can I retrieve video ids from a given playlist id? Here is a snippet but it only yields general information of the playlist: require 'vendor/autoload.php'; use Madcoda\Youtube; $youtube = new Youtube(array('key' => '<API KEY>')); // Return a std PHP object $playlist = $youtube->getPlaylistById('PL590L5WQmH8fJ54F369BLDSqIwcs-TCfs'); echo "<pre>"; print_r($playlist); echo "</pre>" php youtube youtube-api shareimprove this question asked Nov 8 '14 at 14:05 Code_Ed_Student 84511228

Yes, you can ! With the YouTube API v3 with the ressource playlistItems.list Use this parameters to get the video ID of a playlist : part: 'contentDetails' playlistId: 'PL590L5WQmH8fJ54F369BLDSqIwcs-TCfs' https://www.googleapis.com/youtube/v3/playlistItems?part=contentDetails&playlistId=PL590L5WQmH8fJ54F369BLDSqIwcs-TCfs&key={YOUR_API_KEY} The output : "items": [ { "kind": "youtube#playlistItem", "etag": "\"PSjn-HSKiX6orvNhGZvglLI2lvk/OCpNe6AE7ww8_WCYOw2M6axwxAY\"", "id": "PLDWb5NF1kx1qB7HgQ2tJKvLCsn0D34rFYWn3o4SsrJrU", "contentDetails": { "videoId": "Lv-sY_z8MNs" } }, { "kind": "youtube#playlistItem", "etag": "\"PSjn-HSKiX6orvNhGZvglLI2lvk/Qvv0GzRVKvhc4LANFBV171hvlJI\"", "id": "PLDWb5NF1kx1qB7HgQ2tJKvAZrOtpGhFVaTYQJQCi66rE", "contentDetails": { "videoId": "xY_MUB8adEQ" } }, { "kind": "youtube#playlistItem", "etag": "\"PSjn-HSKiX6orvNhGZvglLI2lvk/rRRgwge6ptZxyMRs-RzsvEFU6qs\"", "id": "PLDWb5NF1kx1qB7HgQ2tJKvAI1eXgw8QWwXeA8Anwu4VY", "contentDetails": { "videoId": "xcc9S_ik0v8" } } ... Then you have the video IDs of the playlist. I look up quickly the github you link into in your post, you would have something like this : ( /!\ I haven't tested this code/!) use Madcoda\Youtube; $youtube = new Youtube(array('key' => '/* Your API key here */')); // Set Default Parameters $params = array( 'part' => 'contentDetails', ); $playlistItems = $youtube->getPlaylistItemsByPlaylistId('PL590L5WQmH8fJ54F369BLDSqIwcs-TCfs'); print_r($playlistItems); shareimprove this answer edited Nov 9 '14 at 9:50 answered Nov 8 '14 at 21:16 mpgn 3,01052762

Great, i did now just test it but i get undefined index: results – Code_Ed_Student Nov 9 '14 at 0:09 @Code_Ed_Student if you don't have the base for coding i can't help you. – mpgn Nov 9 '14 at 9:51 Figured it out. Thanks! – Code_Ed_Student Nov 9 '14 at 12:43 I've found that this does not seem to work with the PHP library. A response is sent, but items array is blank. – Solid I Mar 11 '15 at 23:55

Installing Composer globally on CentOS 6.4

http://codybonney.com/installing-composer-globally-on-centos-6-4/

Composer is a PHP dependency manager. To install it globally on CentOS follow the steps below.

First, go to the /tmp directory

cd /tmp  

Download the composer.phar file

curl -sS https://getcomposer.org/installer | php  

Move it to /usr/local/bin/

mv composer.phar /usr/local/bin/composer  

now you should be able to use the command composer globally.
