Programming basics[1]
A conditional statement evaluates an expression and executes instructions depending on the outcome of the evaluation. Most of the time, the evaluation is boolean (true or false).
An example of a simple conditional in PHP can be found below:
<?php
# this file is used to teach the VERY BASICS of conditions in php
$secret_number = 54;
$player_guess = 54;
if ($player_guess == $secret_number) {
echo "You guessed it!";
} elseif ($player_guess >= $secret_number) {
echo "a bit high...";
} elseif ($player_guess <= $secret_number) {
echo "a bit low...";
}
?>
A video[edit]
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[edit]
- Define the terms: variable, constant, operator, object.
