Sample code, using the functions substr and iconv_substr,mb_substr

Intercept the Chinese string _ _ www.jb51.net

Description:

The above code uses two functions, iconv_substr and mb_substr, which can intercept the string under the current character to achieve the non-garbled interception of Chinese characters.

How should we choose?

1. The iconv library may not run correctly on some operating systems, so you need to install the GNU extension library to ensure its normal operation. The mb_substr function is more compatible.

2. The iconv function converts the current string to the corresponding encoding before intercepting, while the mb function intercepts the current string directly according to the specified encoding (providing secure multi-byte interception), so the mb function is more efficient.

Therefore, the mb_substr function to intercept Chinese strings is the most appropriate choice.
