A simple instance _php instance used by the PHP for loop

A For loop is used when you know in advance how many times a script needs to run.

Grammar

for (initial value; condition; increment) 
{ 
code to execute; 
} 

Parameters:

• Initial value: primarily initializes a variable value that is used to set a counter (but can be any code that executes once at the beginning of the loop).

• Condition: The restriction condition for circular execution. If TRUE, the loop continues. If FALSE, the loop ends.

• Increment: primarily for incrementing counters (but can be any code that executes at the end of the loop).

Note: The above initial and incremental parameters can be empty or have multiple expressions (separated by commas).

The following instance defines a loop with an initial value of I=1. The loop continues to run as long as the variable i is less than or equal to 5. Each time the loop is run, the variable i increments by 1:

<?php for 
($i =1 $i <=5; $i + +) 
{ 
echo "the number is". $i. "<br>"; 
> 

Output:

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