Overview
The while loop executes a block of code repeatedly until the condition is FALSE.
Syntax:
while (condition is true) {
code to be executed;
}
Example:
$number = 1;
while($num <= 5) {
echo "The number is: $num
";
$num++;
}
- $num = 1; - Initialize the loop counter ($num), and set the start value to 1
- $num <= 5 - Continue the loop as long as $num is less than or equal to 5
- $num++; - Increase the loop counter value by 1 for each iteration
