I have the following text as an example:
\n\t\t\t\t\t3 comments
Can anyone help me to construct PHP regex formula for extracting the number? (in this case number = 3)
The number can be prefixed by any text, but after the number there should be a <space> followed by comments.
Thanks.
$text = '\n\t\t\t\t\t3 comments';
if (preg_match('/(\d+)\scomments/', $text, $match)) {
$number = $match[1];
} else {
// the number was not found
}
This will match any number if it exists in the string and will assign it to the variable $number. If the number was not found, you can handle it in the else statement.
$number = $match[1]; it will give you only the number, because this is stored in the capture group 1.preg_match('/\d+(?= comments)/', $text, $match);
$str = "\n\t\t\t\t\t3 comments";
preg_match('/\.*(\d+)\scomments/',$str,$m);
var_dump($m[1]);
preg_match("/(\d+)\s+comments/", $text, $match);
print_r($match);
