「三」PHP中字符串的处理

①、将数组拼接成字符串
<?php /** * Created by PhpStorm. * User: autofelix * Date: 12/17/20 * Time:
10:48 PM * Desc: 字符串处理 */ $arr = ['autofelix', 'love', 'csdn']; $str =
implode(',', $arr); echo $str;
* 结果 autofelix,love,csdn
②、将字符串以某个字符串进行分割成数组
<?php /** * Created by PhpStorm. * User: autofelix * Date: 12/17/20 * Time:
10:48 PM * Desc: 字符串处理 */ $str = 'autofelix|handsome|forever|young'; $arr =
explode('|', $str); echo json_encode($arr);
* 结果 [ "autofelix", "handsome", "forever", "young" ]
③、将字符串以单个字符串进行分割成数组或者指定长度的字符分割
<?php /** * Created by PhpStorm. * User: autofelix * Date: 12
