Solution to the 'Rule Error' prompt when there is '|' in regular verification in ThinkPHP5

When there is "|" in the regular rule, it will cause a parsing error:

'regex:\d{3,4}[\s,-]?\d{7,8}|1[3,4,5,8]\d[\s,-]?\d{4}[\s,-]?\d{4}'

Using array syntax can solve it:

['regex' => '\d{3,4}[\s,-]?\d{7,8}|1[3,4,5,8]\d[\s,-]?\d{4}[\s,-]?\d{4}']
