FOR loop in php

for loop in php with example
for(initilization;condition;steping) {
steps to do;
}
//writting a program to generate a table of an entered number

PHP Code:


			
$varNumber=5;

//For output on browser

$varLine='<br>'; 

//For output other than browser

 //$varLine="\n"; 

for($cnt=1;$cnt<=10;$cnt++) {

    $varResult=$varNumber*$cnt;

    echo $varNumber.'X'.$cnt.'='.$varResult.$varLine;

}

output
5X1=5
5X2=10
5X3=15
5X4=20
5X5=25
5X6=30
5X7=35
5X8=40
5X9=45
5X10=50

another example of for loop by printing the factorial of the number

PHP Code:


			
$num=5;

$res=1;

for(;$num>=1;$num--) {

    $res*=$num;

    if($num==1) {

        echo $num.'=';

    } else {

        echo $num.'X';

    }

}

echo $res;

output is 5X4X3X2X1=120
