php数组如何修改值
发布时间：2025-07-08 点击：21
php数组修改值的方法：首先创建一个php示例文件；然后通过“foreach($pid_arr_t as $key=>$value){$value['opid'] = 123;…}”方法修改数组中某个元素值即可。

php 修改数据中某个元素值，其它元素值不变。
循环数组
array(8) { [0] => array(10) { ["opid"] => int(0) ["pid"] => int(11) ["price"] => string(4) "0.10" ["controller"] => string(4) "live" ["type_mold"] => int(1) ["img"] => string(0) "" ["description"] => string(4) "1212" ["title"] => string(12) "测试回放" ["user_id"] => int(51) ["limit"] => string(19) "2020-01-25 15:03:14" } [1] => array(10) { ["opid"] => int(0) ["pid"] => int(10) ["price"] => string(4) "0.10" ["controller"] => string(4) "live" ["type_mold"] => int(1) ["img"] => string(0) "" ["description"] => string(2) "12" ["title"] => string(12) "线上测试" ["user_id"] => int(51) ["limit"] => string(19) "2019-10-17 15:03:14" } [2] => array(10) { ["opid"] => int(0) ["pid"] => int(3) ["price"] => string(4) "1.00" ["controller"] => string(4) "live" ["type_mold"] => int(1) ["img"] => string(0) "" ["description"] => string(4) "1212" ["title"] => string(21) "测试保长时直播" ["user_id"] => int(51) ["limit"] => string(19) "2019-10-17 15:03:14" } [3] => array(10) { ["opid"] => int(0) ["pid"] => int(2) ["price"] => string(4) "0.10" ["controller"] => string(5) "video" ["type_mold"] => int(2) ["img"] => string(0) "" ["description"] => string(130) "最近长安刚刚公布了全新中型suv cs85的预售价格，售价区间为14.99-17.19万元，成为长安首款轿跑suv。" ["title"] => string(142) "测试点播最近长安刚刚公布了全新中型suv cs85的预售价格，售价区间为14.99-17.19万元，成为长安首款轿跑suv。" ["user_id"] => int(51) ["limit"] => string(19) "2019-10-17 15:03:14" } [4] => array(10) { ["opid"] => int(0) ["pid"] => int(8) ["price"] => string(4) "0.00" ["controller"] => string(4) "shop" ["type_mold"] => int(4) ["img"] => string(0) "" ["description"] => string(0) "" ["title"] => string(3) "111" ["user_id"] => int(51) ["limit"] => string(19) "2019-10-17 15:03:14" } [5] => array(10) { ["opid"] => int(0) ["pid"] => int(61) ["price"] => string(4) "0.00" ["controller"] => string(9) "testpaper" ["type_mold"] => int(3) ["img"] => string(45) "20190403/c378d2084ec9c3f05ceab36c00ac67a4.png" ["description"] => string(6) "健康" ["title"] => string(12) "健康管理" ["user_id"] => int(51) ["limit"] => string(19) "2022-01-14 15:03:14" } [6] => array(10) { ["opid"] => int(0) ["pid"] => int(55) ["price"] => string(4) "0.00" ["controller"] => string(9) "testpaper" ["type_mold"] => int(3) ["img"] => string(45) "20190330/af4db555769d71589ae163bfd0a3c05b.jpg" ["description"] => string(3) "111" ["title"] => string(27) &q
