Comparison operators, as their name implies, allow you to compare two values. You may also be interested in viewing the type comparison tables, as they show examples of various type related comparisons.

**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.
