很多时候我们需要将中文简体转换成繁体，或是将繁体转换成简体，那么你知道该如何进行转换吗？今天小编要带大家一起了解php进行中文繁简体转换的方法，有需要的小伙伴可以参考参考。

<?php
$testC = new TestC ();
$testC->index ();
class TestC {
    private $utf8_gb2312;
    
    private $utf8_big5;
    
    public function __construct() {
        $this->utf8_gb2312 = "么万与丑专业丛东丝丢两严丧个丬丰临为丽举么义乌乐乔习乡书买乱争于亏云";
        
        $this->utf8_big5 = "麽萬與醜專業叢東絲丟兩嚴喪個爿豐臨為麗舉麼義烏樂喬習鄉書買亂爭於虧雲";
    }
    
    public function index() {
        // 设置网页UTF8编码
        header ( "Content-Type: text/html; charset=utf-8" );
        
        // UTF8内简转繁
        $str = "中华人民共和国";
        $str_big5 = $this->c2t ( $str );
        echo "原文：$str <br />";
        echo "转换为繁体后： $str_big5 <br />";
        
        // UTF8内繁转简
        $str = "中華人民共和國 ";
        $str_gb2312 = $this->t2c ( $str );
        echo "原文： $str <br /> ";
        echo "转换为简体后：$str_gb2312 <br /> ";
    }
    
    public function c2t($str) {
        $str_t = '';
        $len = strlen ( $str );
        $a = 0;
        while ( $a < $len ) {
            if (ord ( $str {$a} ) >= 224 && ord ( $str {$a} ) <= 239) {
                if (($temp = strpos ( $this->utf8_gb2312, $str {$a} . $str {$a + 1} . $str {$a + 2} )) !== false) {
                    $str_t .= $this->utf8_big5 {$temp} . $this->utf8_big5 {$temp + 1} . $this->utf8_big5 {$temp + 2};
                    $a += 3;
                    continue;
                }
            }
            $str_t .= $str {$a};
            $a += 1;
        }
        return $str_t;
    }
    
    public function t2c($str) {
        $str_t = '';
        $len = strlen ( $str );
        $a = 0;
        while ( $a < $len ) {
            if (ord ( $str {$a} ) >= 224 && ord ( $str {$a} ) <= 239) {
                if (($temp = strpos ( $this->utf8_big5, $str {$a} . $str {$a + 1} . $str {$a + 2} )) !== false) {
                    $str_t .= $this->utf8_gb2312 {$temp} . $this->utf8_gb2312 {$temp + 1} . $this->utf8_gb2312 {$temp + 2};
                    $a += 3;
                    continue;
                }
            }
            $str_t .= $str {$a};
            $a += 1;
        }
        return $str_t;
    }
