How to execute a PHP file via the command line and output the results

Today I am going to show you how to execute a PHP file via a command line interface and output the result to the terminal. You will also learn how to pass in arguments to the PHP file.

The first step is to test to see if the global "argv" variable is set. If it is, then we can run our program and get the array of arguments passed to our script. 

if(isset($argv)) {

Side note, you can read the history behind ARGV here: https://flatironschool.com/blog/a-short-explanation-of-argv

The next step will be to slice our argument's array into a string and populate our $_GET array with the new key value variables we have passed in.

parse_str(
    join( "&", array_slice( $argv, 1 )
), $_GET );

Lastly, we will print out the new array to see the results.

    echo "\n";
    print_r($_GET);
    echo "\n";
}

To test this script you will need to find the full path to your command line PHP executable file. You can then open up a command line terminal. I used windows cmd utility for this example. The command example:

C:\xampp\php\php.exe C:\xampp\htdocs\test\run.php test1=a test2=b

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"...
