Symfony 验证错误：preg_match()：编译失败：字符 class 在偏移处的范围乱序

Question

When I was verifying the operation of the app that was updated from Symfony 2.x to Symfony 4.4, the following error occurred.
The function I was verifying was to enter the id "." To be validated and verify that the validation works correctly, Half-width alphanumeric characters, underscores (_), hyphens (-). and dots (.) Can be used in the target area.
Is there anything you can think of?
I deleted form.errors, but it didn't work.

Error

preg_match(): Compilation failed: range out of order in character class at offset 13

Answer 1

I changed the regex and it worked fine.
The regular expression method may have changed due to the php version upgrade.

pattern: "/^[a-zA-Z0-9-_.]+$/"
