例如:$str = "测试文字";

我要得到 %测%试%文%字%


回复讨论(解决方案)

$str = "测试文字";echo join('%', preg_split('//u', $str));
%测%试%文%字%

如果不是 utf-8 的,请自行完成编码转换

echo join("%",preg_split('/(?<!^)(?!$)/u','测试文字' ));

我测试 怎么不是“%测%试%文%字%”,还是“测试文字”呢

最好用个for 循环的

那你就是 gbk 编码的了
$s = '测试文字';
echo '%' . join('%', str_split($s, 2)) . '%'; //%测%试%文%字%
