In this post, we’ll explore the differences between the two, and when you should use each language in development projects.
Let’s begin by looking at how these languages came into being.
PHP is an open source language created in 2004 by Rasmus Lerdorf. The name came from Personal Home Page Tools — a set of scripts used by Rasmus to track visits to his site.
So, both languages have been around for some time.
Now we’ll look at some of their other similarities.
Scripting languages tend to be interpreted rather than compiled. That means they are translated into machine code via a third party rather than directly. This has an impact on their runtime.
Think of it this way: imagine you want to translate a web page from your native language into Navajo. If you didn’t know the Navajo language you’d need an interpreter to help you, and the translation would take more time.
This is why compiled languages tend to be faster than interpreted languages.
Typing of Variables
This means that when you create a variable in either language, you do not need to assign its data type: it is assumed.
So, you can write the following in PHP:
$x = 'Hello world'; $y = 'Bonjour le monde';
var x = 'Coding is fun'; let y = 'No, honestly';
In both languages, these variables will be recognized as strings (sets of characters).
This is opposed to a strongly typed language like Java, where you must say what type of variable you are using when you declare it:
int x = 5;
