如何检查一个php数组，该数组包含与其他数组相同的值

我有两个数组，分别是$a和$b，其中数组的值相同，但元素的索引不同。 $a Array ( [0] => there is bald spot on the inside or outside of tyre [1] => uneven tyre wear ) $b Array ( [0] => uneven tyre wear [1] => there is bald spot on the inside or outside of tyre ) 但是当我使用进行比较时$a == $b，false即使数组中的元素相同（即使元素的位置不同），它也会返回。

之前给出的解决方案是

$a = Array ( 0 => 'there is bald spot on the inside or outside of tyre', 1 => 'uneven tyre wear'

);

$b = Array ( 0 => 'uneven tyre wear', 1 => 'there is bald spot on the inside or outside of tyre' );

if(count(array_diff($a,$b)) == 0){ echo "both array are identical";

} 但是如果我从$ a中删除一个元素

$a = Array ( 0 => 'there is bald spot on the inside or outside of tyre' //1 => 'uneven tyre wear'

); 如果使用上述解决方案，它仍然显示相同的内容。
