PHP字符串如何将模式后的部分提取到单独的变量中

Question

I have a string that collects two pieces of information. Everything before the slash is a search variable, and everything after is the page number.

Assume the following:

$search = "classic rock/8"

should be $searchvalue[0]='classic $searchvalue[1]='rock' $searchvalue[x]= etc... and then $page=8

I tried a few approaches, the last one is to do three passes by first removing everything after the slash.

$search=substr($search, 0, strpos($search, '/'));

and then separate the $search values into an array. and then go back (a 3rd time!) and get the page variable by deleting everything before the slash.

I know this is highly inefficient. Is there a way to do these actions in one pass?

Thanks in advance!

Answer 1

You can explode that string twice and get the same results!

$res = explode("/", $search); 
$page = $res[1]; //This is the page

$searchValues = explode(" ", $res[0]); //These are the results
