PHP - 正则表达式从字符串的开头和结尾删除单引号

Question

I have a string variable like $string = "'dj12JKmi3433Kl09'". How to remove the single quotes ' from the beginning and end of the string using a preg_replace function? Thanks for your help.

Answer 1

You don't really need a regex for this; you can just use trim(), as in trim($string, "'").

If you really want a regex for some reason, this one would do it:

/^'+|'+$/

Just replace with ''.
