Using PHP and FFmpeg / FFprobe to get the width and height of a video

For this example I am using Moo0 on a Windows machine. Moo0 FFmpeg/FFprobe are tools used to convert video files and get information about videos. The download page is located here: https://www.moo0.com/software/FFmpeg Please take note that after you download it, to where you installed it on your machine. I am assuming you already have PHP installed on your machine and can run PHP scripts. 

To get started, after you have installed it, you need to find the location of binaries folder for Moo0. After I installed it on my machine the location was here: C:\Program Files (x86)\Moo0\FFmpeg 1.07\bin\ffprobe.exe.

Now we can create the command to run that will return our width and height of our video file:

$cmd = " -show_entries stream=width,height -of default=nw=1:nk=1 a.mp4";

Next I am using the PHP function popen to run the command as a background process.

$open = popen('start /B "" "C:\Program Files (x86)\Moo0\FFmpeg 1.07\bin\ffprobe.exe"'. $cmd.'', "r");

Now we will loop through the results of the command to get the width and height of the video and close the pointer.

$dim = array();

while($bstream = fgets($open, 2048)) {
    $dim[] = trim($bstream);
} 

pclose($open);

Now that we have the dimensions in an array, we can print them out to see the results.

print_r($dim);

Example output of the width and height:

Array ( [0] => 1280 [1] => 720 ) 

That is it. Please note that I used ffprobe.exe to get the dimensions in this example. Have a nice day. 😊

An example of chaining jQuery Ajax request callbacks

Chaining is a great way to separate your Ajax request callbacks' code and run multiple commands/functions on one element in a row. The fail callback function is a must for finding out if anything goes wrong with the HTTP request. I recommend the below code for alerting your user of anything going wrong with a request. You can have the error posted to any notification system you have. For demo purposes, I am using the vanilla alert function. As a bonus, I have added comments to the code for explanation. $.ajax({     // request information goes here }).done(function(data,textStatus,jqXHR){     // handling of successful requests goes here      // please note this will not fire if there is a failed request, use the always chain for that }).fail(function(jqXHR, exception) {     // handling of bad requests goes here     if (jqXHR.status === 0) {         alert('Could not connect to the s...

Creating hashtag hyperlinks on the fly for your website

In this post I am going to show you how to take any string of text containing hashtags and convert them into clickable URLs, AKA "hyperlinks". Okay, to get started we will first need some text containing hashtags. $text = 'You can find #programming help at my #blog.'; Now we will use the following regular expression pattern to find all hashed words in the string. $pattern = "/\#([A-Za-z0-9_-]*)/is"; It's important to note, that with this pattern, if you include anything inside the brackets, like a period after the 9, it will find the period with the word. With this pattern we can pass it into the PHP preg_replace_callback function. The callback function will return our matches found and replace all hashtags with clickable URLs. $text = preg_replace_callback($pattern,      function($matches){           $nohash = str_ireplace('#','',$matches[0]);           return '<a href="?tag='.$nohash.'" target="_self"...
