Custom Routines (C++ and PHP Cross Reference Guide)

By Mike Prestwood

C++ versus PHP: A side by side comparison between C++ and PHP.

 
Language Details
 

Language Details is kind of a catch all for stuff that didn't make it into language basics nor any other category.

Custom Routines

[Other Languages] 

Languages Focus

For non-OOP languages, a custom routine is a function, procedure, or subroutine and for pure OOP languages, a custom routine is a class method. Hybrid languages (both non-OOP and OOP) combine both.

C++: 

C++ is a hybrid language and as such offers global functions and class methods. A function must come before it's usage or you can prototype the function.

Syntax Example:
void sayHello(string pName) {
cout << "Hello " + pName + "\n";
};
 
int add(int p1, int p2) {
int result;
 
  result = p1 + p2;
return result;
};
PHP:  "Custom Function" function

PHP uses functions and loosely typed parameters. Function definitions can come before or after their usage so my preference when mixing PHP in with a mostly HTML page is to put the functions after the </html> tag.

Syntax Example:
function sayHello($pName) {
 echo "Hello " . $pName . "<br>";
}
 
function add($p1, $p2) {
 return $p1 + $p2;
}
