PHP if else statement- Normal and advanced

Here now I am giving you the normal code example.

$test = 100;

if ( $test == 100 ) {
echo “The if statement evaluated to true”;
} else {
echo “The if statement evaluated to false”;
}

If you want to use this in one line than use following code:

echo $testprint = ( $test == 100 ) ?  “The if statement evaluated to true” : “The if statement evaluated to false”;

This will gives you same output.

Now I am giving you the multiple IF else statment in very short way.

if ( one= true ){
if ( two=true){
echo “one”;
}else{
echo “two”;
}
}else{
echo “nothing”;
}

Short way:

$shortway = (one= true) ? (two=true ) ? “one” : ‘two’ ) : “nothing”;

Normal code for ELSIF

print “Variable is 10″
elsif var == “20″
