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

**Table 10-4. Comparison Operators**

Example | Name | Result |
---|---|---|

$a == $b | Equal | if $a is equal to $b.TRUE |

$a === $b | Identical |
if $a is equal to $b, and they are of the same
type. (PHP 4 only)
TRUE |

$a != $b | Not equal | if $a is not equal to $b.TRUE |

$a <> $b | Not equal | if $a is not equal to $b.TRUE |

$a !== $b | Not identical |
if $a is not equal to $b, or they are not of the same
type. (PHP 4 only)
TRUE |

$a < $b | Less than | if $a is strictly less than $b.TRUE |

$a > $b | Greater than | if $a is strictly greater than $b.TRUE |

$a <= $b | Less than or equal to | if $a is less than or equal to $b.TRUE |

$a >= $b | Greater than or equal to | if $a is greater than or equal to $b.TRUE |

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