By Mike Prestwood

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

Statements

Common statements such as if statements, loops, etc.

Exception Trapping

[Other Languages]

Languages Focus

A common usage of exception handling is to obtain and use resources in a "try-it" block, deal with any exceptions in an "exceptions" block, and release the resources in some kind of "final" block which executes whether or not any exceptions are trapped.

C++: try/catch

Syntax Example:

try {

  //Some code.

catch(AnError) {

  //Error code here.

[Not specified yet. Coming...]

If Statement

[Other Languages]

C++: if..else if..else

Same as standard C.

Syntax Example:

//C++Builder example using the VCL ShowMessage.

int x;

x = 8;

if (x == 10) {
  ShowMessage("x is 10.");
} else if (x < 10) {
  ShowMessage("x is less than 10.");
} else {
  ShowMessage("x must be greater than 10.");
}

PHP: if..elseif..else

The PHP if statement consists of using if, elseif, and else.

Syntax Example:

$x = 8;

if ($x == 10) {
 echo "x is 10.";  
} elseif ($x < 10) {
 echo "x is less than 10.";
} else {
 echo "x must be greater than 10.";  
};
