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 Not identical
True if $a is not equal to $b, or they are not of the same
type. (PHP4 only)
$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.
This expression evaluates to
expr2 if
expr1 evaluates to true, and
expr3 if
expr1 evaluates to false.
