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 15-4. 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. (introduced in PHP 4)
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. (introduced in PHP 4)
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 |

If you compare an integer with a string, the string is converted to a number. If you compare two numerical strings, they are compared as integers. These rules also apply to the switch statement.

Another conditional operator is the "?:" (or ternary) operator.
