How to convert Chinese characters to utf8 in php
php汉字转utf8的实现方法:首先创建一个php文件;然后自定义一个“htou”方法以及“utf8_unicode”方法;接着在代码中实现隐藏utf8格式的字符串;最后运行“utf8_unicode”方法即可转换汉字。
php自定义函数实现汉字转换utf8编码的方法:
该函数有两部分组成:
function htou($c) { $n = (ord($c[0]) & 0x1f) << 12; $n += (ord($c[1]) & 0x3f) << 6; $n += ord($c[2]) & 0x3f; return $n; } //在代码中隐藏utf8格式的字符串 function utf8_unicode($str) { $encode=''; for($i=0;$i<strlen($str);$i++) { if(ord(substr($str,$i,1))> 0xa0) { $encode.='&#'.htou(substr($str,$i,3)).';'; $i+=2; } else { $encode.='&#'.ord($str[$i]).';'; } } return $encode; }
我们可以用 utf8_unicode() 就可以转换汉字,返回为汉字的utf8编码。这样输出网页不会是乱码。
