php - 如何将一个字符串与另一个字符串值精确匹配？

Question

我有一个表值，如下字符串:

PhysicalAddress:E8-6A-64-DE-48-60PhysicalAddress:04-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-8FPhysicalAddress:06-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-92

我得到如下随机/随机顺序的值，以验证它们是否与表值完全匹配:

PhysicalAddress:E8-6A-64-DE-48-60PhysicalAddress:04-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-8FPhysicalAddress:06-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-92

or 

PhysicalAddress:04-EA-56-08-E6-92PhysicalAddress:E8-6A-64-DE-48-60PhysicalAddress:04-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-8FPhysicalAddress:06-EA-56-08-E6-8E

or

PhysicalAddress:06-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-92PhysicalAddress:E8-6A-64-DE-48-60PhysicalAddress:04-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-8F

or

PhysicalAddress:04-EA-56-08-E6-8FPhysicalAddress:06-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-92PhysicalAddress:E8-6A-64-DE-48-60PhysicalAddress:04-EA-56-08-E6-8E

or


PhysicalAddress:04-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-8FPhysicalAddress:06-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-92PhysicalAddress:E8-6A-64-DE-48-60

尝试过:

select *from table1 where preview like '%PhysicalAddress:04-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-8FPhysicalAddress:06-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-92PhysicalAddress:E8-6A-64-DE-48-60%' limit 1;

但这不是正确的SQL，输入值是随机的，在数据​​库值固定的情况下进行打乱，我需要将随机的打乱输入与固定数据库值匹配。如何使其非常稳定？

实现此目的的一种方法是将传入字符串拆分为单独的地址，然后检查它们是否全部与表值匹配:

$string = 'PhysicalAddress:E8-6A-64-DE-48-60PhysicalAddress:04-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-8FPhysicalAddress:06-EA-56-08-E6-8EPhysicalAddress:04-EA-56-08-E6-92';
$components = str_split($string, 33);
$query = "SELECT * 
FROM table1 
WHERE preview LIKE '%" . implode("%'\n  AND preview LIKE '%", $components) . "%'";
echo $query;

输出:

SELECT * 
FROM table1 
WHERE preview LIKE '%PhysicalAddress:E8-6A-64-DE-48-60%' 
  AND preview LIKE '%PhysicalAddress:04-EA-56-08-E6-8E%'
  AND preview LIKE '%PhysicalAddress:04-EA-56-08-E6-8F%'
  AND preview LIKE '%PhysicalAddress:06-EA-56-08-E6-8E%'
  AND preview LIKE '%PhysicalAddress:04-EA-56-08-E6-92%'
