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) "模板导入试卷测试一"    ["user_id"] => int(51)    ["limit"] => string(19) "2019-05-01 15:03:14"  }  [7] => array(10) {    ["opid"] => int(0)    ["pid"] => int(62)    ["price"] => string(7) "1000.00"    ["controller"] => string(9) "Testpaper"    ["type_mold"] => int(3)    ["img"] => string(45) "20190330/f1cc9c7df38108c505338a529e3d06a6.jpg"    ["description"] => string(18) "法学概论201704"    ["title"] => string(18) "法学概论201704"    ["user_id"] => int(51)    ["limit"] => string(19) "2019-07-29 15:03:14"  }}

方法:

foreach($pid_arr_t as $key=>$value){  $value['opid'] = 123;  $pid_arr_t[$key] = $value;             }

只有修改opid的元素值.
