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
Parameters | Similarities |
---|---|

Differences between PHP and C
Parameters | PHP | C |
---|---|---|
Data types | PHP has only two numerical data type:
Strings are of random length and there is no character data type available in PHP. | C has:
|
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. |
Array | 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. |
