# Comparison Operators

Comparison operators, as their name implies, allow you to compare two values.

Table 10-3. Comparison Operators

example | name | result
--- | --- | ---
$a == $b | Equal | True if $a is equal to $b.
$a === $b | Identical | True if $a is equal to $b, and they are of the same type. (PHP4 only)
$a != $b | Not equal | True if $a is not equal to $b.
$a < $b | Less than | True if $a is strictly less than $b.
$a > $b | Greater than | True if $a is strictly greater than $b.
$a <= $b | Less than or equal to | True if $a is less than or equal to $b.
$a >= $b | Greater than or equal to | True if $a is greater than or equal to $b.

Another conditional operator is the "?:" (or trinary) operator, which operates as in C and many other languages.

      1
      2 (expr1) ? (expr2) : (expr3);
      3

This expression evaluates to `expr2` if `expr1` evaluates to true, and `expr3` if `expr1` evaluates to false.
