回复内容:
$a = '辣fdsfd4352椒素的林凤娇阿隆索丹甫股份fds啊';
$b = '素' 怎么查到他在第12个
撸主问的是出现 12,基于上面同学的贡献纠正下答案:
$a = '辣fdsfd4352椒素的林凤娇阿隆索丹甫股份fds啊'; $b = '素'; $char_pos = strpos($a, $b); // 15 // 查找中文位置,需要结合 mb* 函数 mb_internal_encoding('UTF-8'); $pos = mb_strpos($a, $b) + 1; // 12
<code>$a = '辣fdsfd4352椒素的林凤娇阿隆索丹甫股份fds啊'; $b = '素'; $pos = strpos($a, $b); </code>
<code> strpos($a, $b); </code>
mb_ 获取自然长度
