The php not equal comparison operator is != or <>.
!= Not equal to $x != $y Returns true if $x is not equal to $y.
Code example:
<?php $x = 17; $y = "17"; var_dump($x != $y); // 返回 false，因为值相等 ?>
Output:
bool(false)
<> not equal to $x <> $y If $x is not equal to $y, return true.
<?php $x = 17; $y = "17"; var_dump($x <> $y); // 返回 false，因为值相等 ?>
Output:
bool(false)
