不要在正则表达式输出中显示空格

Question

I need to match everything but not the white spaces

For example in this string : 16790 - 140416 / 3300

I want to have the following result made by regex (and PHP) without white spaces: 140416/3300

I used : \s+\d+\s+-\s+(\d+\s+\/\s+\d+) and of course it gave me the results with the whitespaces:

140416 / 3300

How could I have a match 1 result without white spaces ?

Thank you

Answer 1

$subject = "16790 - 140416 / 3300";
$result = preg_replace('%.*?(\d+)\s+/\s+(\d+)%', '$1/$2', $subject);
echo $result;
// 140416/3300
