if you want to have two expressions you can
use any logical operators 'and', 'or'
<?php
if ($num > 10 and $num < 15)
{
echo "number is greater than 10 but less than 15";
}
?>
another way, you can enclose each expression into
open/close parentheses - ( expression1 ) and (expression2)
so that its easy to analyze your expressions
<?php
if ( ($num > 10) and ($num < 15) )
{
echo "number is greater than 10 but less than 15";
}
?>
i prefer using the wordings 'and' instead of '&&' operator
because wordings operators are easy to analyze and easy
to your eye to read especially for long expressions.
the '&&' tends to be confused to $ sign
