Comparison Operators
Comparison
operators allow you to compare two values. Based on the result of comparison,
the result is either TRUE or FALSE. The table below lists comparison operators
along with description and examples.
In the examples
below A = 10 and B = 20.
Example:
Script:
Comparision_op.php
<html>
<head>
<title>Comparision Operators</title> </head>
<body>
<?php
$a = 34;
$b = 45;
echo
"a=".$a."</br>";
echo
"b=".$b."</br>";
if( $a == $b ){
echo "Equality operator : a is equal to b<br/>";
}
Else
{
echo
"Equality operator : a is not equal to b<br/>";
} else{
echo
"Equality Operator : a is not equal to b<br/>";
}
if( $a > $b ){
echo
"Greater than operator : a is greater than b<br/>";
} else {
echo
"Greater than operator : a is not greater than b<br/>";
}
if( $a < $b ){
echo "Less than operator : a is less than b<br/>";
} else {
echo "Less
than operator : a is not less than b<br/>";
}
if( $a != $b ){
echo "Not
Equal Operator : a is not equal to b<br/>";
} else{
echo "Not
Equal Operator : a is equal to b<br/>";
}
if( $a >= $b
){
echo
"Greater than or equal operator : a is either grater than or equal to
b<br/>";
} else {
echo
"Greater than or equal operator : a is nieghter greater than nor equal to
b<br/>";
}
if( $a <= $b
echo "Less than or equal operator : a is either less than or equal to
b<br/>";
} else {
echo "Less
than or equal operator : a is nieghter less than nor equal to
b<br/>";
}
?>
</body>
</html>
OUTPUT:
A=34;
B=45;
Equality
operator: a is not equal to b
Greater than
operator: a is not greater than b
Less than operator:
a is less than b
Not Equal Operator:
a is not equal to b
Greater than or
equal operator: a is neither greater than nor equal to b
Less than or
equal operator: a is either less than or equal to b
