在php中将字符串转换为数字

Question

I have this line of code...

$ide=str_replace('idEdu=', '', $_SERVER['QUERY_STRING']);

In which i get a string which is always a number and I want this string to make it integer.

I want to get for example the number 3 for the url which can be like this one addCV.php?idEdu=3

Can you help me please to achieve that? Thank you

Answer 1

You can either cast as int or use intval():

 $num=(int)$_GET['idEdu'];

or

 $num=intval($_GET['idEdu']);

Casting should be 4 times as fast.

Answer 2

你有没有尝试过？

$ide = intval(str_replace('idEdu=', '', $_SERVER['QUERY_STRING']));
