while programming as kaman writes these are the basic and after that you must have the knowledge of the control structure how to use and where to use
like if condtion
for loop
while loop
do while
switch case
and another loop in php is foreach
loops have the major roll in controling the flow of program
while loop
replace \n with <br> if usingbrowser for output

PHP Code:


			
$num=1;

while($num<=5){

    $i=1;

    while($i<=$num){

        echo $i;

        $i++;

    }

    echo "\n";

    $num++;

}

out put is
1
12
123
1234
12345
just do nothing revers the loop

PHP Code:


			
$num=5;

while($num>=1){

    $i=1;

    while($i<=$num){

        echo $i;

        $i++;

    }

    echo "\n";

    $num--;

}

output
12345
1234
123
