如何使用PHP准确计算带有特殊字符的字符串中的字符数？

Question

I'm using strlen to calculate the length of a string and if it exceeds x characters, substr it with a ellipses. The problem is, if there are special characters, the strlen function spits out an inaccurate number, causing ellipses to be added to strings that haven't exceeded x characters. What is a good method of calculating the length of a string in a way that works even with special characters involved, preferably counting a special character as a regular character so something like "W^a" counts as three characters.

Answer 1

如果在special characters你的意思是öüóűőúéáí，你可以尝试使用mb_strlen方法http://www.php.net/manual/en/function.mb-strlen.php并将'utf-8'作为第二个参数。
