PHP：从另一个提取字符串

Question

i have some strings (address), all like this:

2 rue lambda, 75018, PARIS

I want to get the postal code, in this exemple "75018". I've been trying different solution, but i'm not familiar with escaped characters , and don't know how to detect coma in the string. Which function should i use to extract the postal code?

Answer 1

you can try this:

preg_match('/([0-9]{5})/',$string,$match);
echo $match[1];

This will work whenever there is an address comma separated or simply space separated
