PHP if -- else statement in conditions

If statement enable programmer to execute a script only when a condition is true.
And Else enable to quickly execute a script when the condition fails.

PHP Code:

<?php
$myname = "Smith" ;
if ( $myname == "Smith" ) {
echo "hello ! Your are Smith"; // wil be displayed only if condition is true
} else {
echo "hello ! Your are not Smith";// wil be displayed only if condition is false
}
?>

This may also be writed like this:

<?php
$myname = "Smith" ;
if ( $myname == "Smith" )
echo "hello ! Your are Smith"; // wil be displayed only if condition is true
else
echo "hello ! Your are not Smith";// wil be displayed only if condition is false
?>

"{" and "}" can be deleted because there is only one line in if and else statements. If you want to create many lines of script, so then you should use"{" and "}":

PHP Code:

<?php
$myname = "Smith" ;
if ( $myname == "Smith" )
{
echo "hello ! Your are Smith"; // wil be displayed only if condition is true
echo "You are wellcome";
} else
echo "hello ! Your are not Smith";// wil be displayed only if condition is false
?>
