Conditionals

Programming basics

A conditional statement evaluates an expression and executes instructions depending on the outcome of the evaluation. Conditionals depend on operators to evaluate if an expression is true or false. A condition and selection are not the same thing. A condition asks a question. A selection processes the answer.

The list below is an example of types of conditional questions:

• Match
• Threshold
• Range
• One-of
• Not-match
• Not one of
• All of
• Some of
• Eligible

An example of a simple conditional in PHP can be found below:

A video

This video references the C programming language and scratch, but the ideas about conditionals are excellent. In the case of conditionals, PHP and C share similar syntax (but not exact).

Standards
