A Loosely typed language is a language that can create variables of different types easily. It refers to those programming scripts that do not require defining a variable type. To put it simply, while declaring a variable in these programming scripts, there is no need of defining or classifying the data type stored in them. While working with these programming scripts, you need to use a sign for each variable type(like string, integer, float, etc.) to declare them. You just need to assign a string value to the variable, to define that our variable is an integer. This is the reason why PHP is a loosely typed language.
What is PHP Script?
As PHP does not require defining the variable type. As a result, you are not restricted to a limited type of data. Quite inevitably, it proves to be highly beneficial for programmers, as they enjoy optimum flexibility.
The PHP script is very much popular among programmers and developers to develop various kinds of applications. As a loosely typed language, this particular script offers golden opportunities to programmers for designing great software programs. It is the most widely used language for developing web applications. There are many factors that attract developers and users to use PHP in their applications. Here in this article, we have jotted down the reasons that make PHP so popular among all –
1. Optimum Flexibility
While creating dynamic applications, it is the flexibility of a loosely typed programming script that renders the most useful assistance. Because of their nature, dynamic applications are quite tough to work with. Often, these applications have to determine actions based on unknown data. Using the PHP programming script proves to be the best shots, in this context. It does not enforce data types on variables, and hence offers complete flexibility in complex programming.
2. Complete Programming Liberty
In cases of strongly typed languages, the programming rules are already pre-set and pre-determined. Therefore, the programmer cannot do any changes to it as per preference. In this context, however, situations are completely different with PHP. By allowing programmers to set their own programming rules, this particular programming script offers them freedom of operation.
3. Simplicity & Cost
The PHP language is one of the most simple programming languages. Like other languages, it is bound to have its bits and bytes, but still, it is compatible to run on any system productively. Writing a PHP script is pretty much straightforward and simple as opposed to another language. It also allows programmers to write customized scripts. The cost factor also makes PHP popular! As PHP is an open-source framework, that means it is completely free to use and is fully supported by documentation.
PHP programming script has gained traction with ingenious programmers and has become their current favorite, but as any other script PHP also comes with its share of drawbacks. While working with PHP, programmers need to have proper knowledge, otherwise, they might create vulnerable programming codes. As a loosely typed language, PHP creates some major possibilities of errors. Say, for instance, your code needs integer input, and your variable is in a string. As the most undesired output, the entire function will break. However, it is possible to overcome this issue by creating a properly structured and organized programming code.
So now you know why PHP is a loosely typed language and why it is so popular. PHP has various advantages and it is widely used for web application development. Want to know more details about PHP?
