我只想在php正则表达式中从连字符前的文本中删除括号

Question

I have this string:

(3330) - PATRIOT SPRAYER (11/08-)

And I want to remove brackets only from 3330 . Expected output:

3330 - PATRIOT SPRAYER (11/08-)

I have tried to use:

$pattern =  ('/[[(.)]]/')

But I don't get my expected result. Where did I go wrong?

Answer 1

You could use ^ to mark the start of the line. This would give you an regex like the following:

^\(([^)]+)\)

and the with php preg_replace

$line = preg_replace('~^\(([^)]+)\)~', '$1', $line);

Answer 2

How about:

$str = '(3330) - PATRIOT SPRAYER (11/08-)';
$str = preg_replace('/\(([^)]+)\)(\s*-)/', "$1$2", $str);
