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"}}
