Difference and Similarities between PHP and C
PHP is a server-side scripting language designed specifically for web development. It can be easily embedded in HTML files and HTML codes can also be written in a PHP file. The thing that differentiates PHP with client-side language like HTML is, PHP codes are executed on the server whereas HTML codes are directly rendered on the browser. C is a procedural programming language. It was initially developed by Dennis Ritchie as a system programming language to write an operating system. The main features of C language include low-level access to memory, a simple set of keywords, and clean style, these features make C language suitable for system programming like an operating system or compiler development.
Similarities between PHP and C
|Operators||All type of operators in C behave in similar way in PHP, such as basic arithmetic, boolean, assignment and comparison operators.|
|Function prototype||User defines functions are named in same way in both the languages.|
Differences between PHP and C
PHP has only two numerical data type:
Strings are of random length and there is no character data type available in PHP.
|Type Conversion||Data types are not checked during compile-time and data type errors are rare to occur. Values and variables are automatically cast into the suitable data type.||In C variables are declared with data types. While some data types have implicit conversion, others need to be type-casted. Data type error occurs in C commonly and should be taken care.|
Superficially they look similar to arrays in C.
|Structure||No structure type needed because of array and objects.||Structure type exists in C.|
|Prototypes||There are no prototype in PHP because function is not required to be declared before it’s implementation.||There are prototypes in C because function is required to be declared before its implementation.|
|Permissiveness||PHP is a lot more lenient when compared to C. More than errors there are unexpected results for making new mistakes.||C will give errors if data type is not declared, array size is not declared, etc. Comparing it to PHP it is a little stricter.|
|Purpose||It is a server-side language.||It is a procedural programming language.|
|HTML Connectivity||Can be merged with HTML file.||Cannot be merged with HTML file.|
