希望使用preg_replace从我的字符串中删除字符

Question

I have the right function, just not finding the right regex pattern to remove (ID:999999) from the string. This ID value varies but is all numeric. I like to remove everything including the brackets.

$string = "This is the value I would like removed. (ID:17937)";
$string = preg_replace('#(ID:['0-9']?)#si', "", $string);

Regex is not more forte! And need help with this one.

Answer 1

Try this:

$string = preg_replace('# \(ID:[0-9]+\)#si', "", $string);

You need to escape the parenthesis using backslashes \.
You shouldn't use quotes around the number range.
You should use + (one or more) instead of ? (zero or one).
You can add a space at the start, to avoid having a space at the end of the resulting string.
