带有所有键盘字符的正则表达式

Question

I need regex with all english keyboard characters that works from all situations. Right now, I'm using this:

/^[a-zA-Z0-9!@#\$%\^\&*)\]\[(+=._-].*/

But the text like this don't work:

"I'm good!", told Billy!

How could I fix this?

Answer 1

preg_match("#^[a-z0-9\r\n\t " . preg_quote('`~!@#$%^&*()_+{}[]:";\'<>?,./'). "].*#i", $string, $matches)

如果您不需要TAB和ENTER键，则可以删除\\r\\n\\t

Answer 2

Space is missing.

The .* at the end is not what you wanted.

Instead, end with * to repeat the character set; then have a $ to 'anchor' the regexp at the end of the string.

/^[ -~]*$/

might work correctly -- it includes space and all visible characters. See an ascii chart to verify. Or you may need to add \\t for tab and something for Return .
