explode()函数语法:
explode(separator,string,limit)
1.参数separator,必须,规定在哪里分割字符串。
2.参数string,必须,定义要分隔的字符串。
3.参数limit,可选,规定所返回的数组元素的数目。

  1. //基于tp5框架,使用explode()函数分隔字符串,并访问分割后的数组元素
  2. $address='河南省,郑州市,金水区';
  3. $prov=explode(",",$address)[0];
  4. $city=explode(",",$address)[1];
  5. $zone=explode(",",$address)[2];
  6. dump($prov);
  7. dump($city);
  8. dump($zone);

输出结果:
string(9) “河南省”
string(9) “郑州市”
string(9) “金水区”
