The for Loop Untuk Loop

The for loop is used when you know in advance how many times the script should run. Untuk loop digunakan ketika Anda tahu sebelumnya berapa kali script harus dijalankan.

Syntax Sintaksis

for ( init; condition; increment ) { code to be executed; }

Parameters:

• init : Mostly used to set a counter (but can be any code to be executed once at the beginning of the loop)
• condition : Evaluated for each loop iteration. If it evaluates to TRUE, the loop continues. If it evaluates to FALSE, the loop ends.
• increment : Mostly used to increment a counter (but can be any code to be executed at the end of the loop)

Note: Each of the parameters above can be empty, or have multiple expressions (separated by commas).

Example

The example below defines a loop that starts with i=1. The loop will continue to run as long as i is less than, or equal to 5. i will increase by 1 each time the loop runs:

"; } ?>

Output:

The number is 1 The number is 2 The number is 3 The number is 4 The number is 5

---

The foreach Loop

The foreach loop is used to loop through arrays.

Syntax

foreach ($ array as $ value ) { code to be executed; }

For every loop iteration, the value of the current array element is assigned to $value (and the array pointer is moved by one) - so on the next loop iteration, you'll be looking at the next array value.

Example

The following example demonstrates a loop that will print the values of the given array:

"; } ?>

Output:
one
two
three
