For loop: loop is basically used
to perform different operations again and again till the end condition.
Syntax:
for (Starting counter; Verifying counter;
increasing counter)
{
Execute
your code;
}
Starting counter: you can declare variable and assign initial counter for loop
Verifying stop counter: While running it will verify where to stop the execution of for loop.
Increasing counter: This counter will increase its value till the verifying stop counter
value
In below example
1:
"$a=1" is starting counter
"$<=10" is verifying stop counter that means it will verify
the condition until it reaches to stop counter i.e. 10 is stop counter here.
$a++ is the Increasing counter, it will increment till stop counter 10,
the double plus sign represent the increase counter by 1
You can also write like this "$a+2" if you want to increase
counter by 2.
Example 1:
Increase Loop
<?php
for($a = 1; $a<=10 ; $a++)
{
echo "This is table of one
: $a <br>";
}
?>
Output:
This is table of one :1
This is table of one :2
This is table of one :3
This is table of one :4
This is table of one :5
This is table of one :6
This is table of one :7
This is table of one :8
This is table of one :9
This is table of one :10
Example 2: Decrease Loop (Reverse Loop)
<?php
for($a = 10; $a<=1 ; $a--)
{
echo "This is Reverse table
of one : $a <br>";
}
?>
Output:
This is Reverse table of one :10
This is Reverse table of one :9
This is Reverse table of one :8
This is Reverse table of one :7
This is Reverse table of one :6
This is Reverse table of one :5
This is Reverse table of one :4
This is Reverse table of one :3
This is Reverse table of one :2
This is Reverse table of one :1
