查询语法中的MySQL REGEX

Question

I have following example array,

Array
(
    [0] => TEST1
    [1] => TEST2
    [2] => TEST3
    [3] => TEST4
    [4] => TEST
    ....
)

Now in Database values stored as

/TEST/IMAGE
/TEST2/VIDEO
/TEST3/MIME
...

Now I want to match the substring found in array when to fetch the data from database:

So, I have applied following query:

SELECT * FROM media_library WHERE 1 AND sDirectory REGEXP '(/TEST1.*)|(/TEST2.*)|(/TEST3.*)|(/TEST4.*)|(/TEST.*)'

But for the syntax '(/TEST1.*)|

I have used for loop

$data = '';$k=0;
foreach($folders as $key => $val){
    $data .= ($k>0) ? "|" : "";
    $data .= "(/".$val.".*)";
    $k++;
}

So, Is there any way to directly use an array which creates format very easily rather than for loop?

Thanks

You can use http://php.net/manual/en/function.array-map.php and after that use implode() .

Something like that:

$regex = implode('|', array_map(function ($value) {
    return "(/{$value}.*)";
}, $yourarray));
