如何从PHP的末尾获取部分字符串？

Question

I am making application where I receive a string from user. The string is concatenated with - character between them. First part of string contains alphabetic data whereas later part contains integers or floating point numbers. For example: A string might be 3 Cups Tea-5.99.I want to get the later part of string 5.99 separated by - character. How to do that? I know about PHP substr() function but that takes fixed characters to retrieve substring from. But in this case the later part will not be fixed. For example: 2 Jeans-65.99. In this case I would need last 4 characters meaning that I can't use substr() function. Anybody with solution? I know I would need to apply regex but I am completely novice in Regex. Waiting for your help. Thanks!

Answer 1

Simply

$result = explode('-', $string)[1];

For PHP<5.4 you'll have to use temporary variable:

$data = explode('-', $string);
$result = $data[1];

Edit

As mentioned in comments, if there is more than 1 part, that will be:

$result = array_pop(explode('-', $string));
