for Loop

The for Loop

The for loop is used when you know in advance how many times the script should run.

Syntax

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).

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.
