指定字符后的PHP字符串拆分

Question

I have this string: galery/1_abc def_120.jpg

how do I get:

$description = "abc def"; // characters between first underscore _ and second underscore _

$price = 120; // numbers between second underscore _ and dot .

I think about preg_split but i have no idea how to use it

Answer 1

$pizza  = "piece1_piece2_piece3";
$pieces = explode("_", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2

In your case:

$url = "galery/1_abc def_120.jpg";
$pieces = explode("_", $url);
echo $pieces[0]; //galery/1
echo $pieces[1]; //abc def
echo $pieces[2]; //120.jpg
