MySQL（PHPMyAdmin）REGEXP，PHP之间的区别

Question

I have regexp for finding external links on my website, it works fine in PHP:

((http|https):\\/\\/(?!siteurl.com)[\\w\\.\\/\\-=?#]+)

Now I want to use it in PHPMyAdmin in Search tab to search in whole database. It doesn't work. Are there any differences between PHP and MySQL REGEXP ? What should be changed in my regexp to make it work in PHPMyAdmin ?

Answer 1

WHERE url     REGEXP '^https?://'
  AND url NOT REGEXP '^https?://siteurl.com'

Why check for stuff after // ? If you do need to, be aware that MySQL does not handle \\w or \\d , so you need something like [-[:alpha:]./=?#]+ . \\w , by itself, is [[:alpha:]] ; \\d is [[:digit:]] . Reference

Answer 2

Use these patterns:

\\d : [a-zA-Z0-9_]

\\w : [0-9]
