Question:-

What is the differences between $a != $b and $a !== $b?

Answer:-

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

$a == $b | Equal | `TRUE` if $a is equal to $b after type juggling. |

$a === $b | Identical | `TRUE` if $a is equal to $b, and they are of the same type. |

$a != $b | Not equal | `TRUE` if $a is not equal to $b after type juggling. |

$a <> $b | Not equal | `TRUE` if $a is not equal to $b after type juggling. |

$a !== $b | Not identical | `TRUE` if $a is not equal to $b, or they are not of the same type. |

$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. |

$a <=> $b | Spaceship | An integer less than, equal to, or greater than zero when $a is respectively less than, equal to, or greater than $b. Available as of PHP 7. |

!= means inequality (TRUE if $a is not equal to $b) and !== means non-identity (TRUE if $a is not identical to $b).
