if else in php

"if else" are simple condition statements.
example:
suppose you are hiring people for job and
if there are scale for jobs:
matric= scale 1
HSSE=scale2
BA=scale 3
MA=scale 4

so this is the criteria for different scale;

now you will check that
if someone is matric he will get scale1 job;
if someone is HSSE he will get scale2 job;
if someone is BAhe will get scale3 job;
if someone is MA he will get scale4 job;
in code:



[code]

<?php

 $person="HSSC";

if($person=="matric")

echo "you can get job in scale 1";

if($person=="HSSC")

echo "you can get job in scale 2";

if($person=="BA")

echo "you can get job in scale 3";

if($person=="MA")

echo "you can get job in scale 4";



?>

[/code]

now you can change the value of variable $person;
like $person="HSSC";
$person="BA";
$person="MA";
