php foreach 修改數(shù)組不生效?

$task_list = [["cid"=1,"level"="1","name"="liming"],["cid"=2,"level"="2","name"="ddd"],["cid"=3,"level"="3","name"="sfsdfsd"]];

$level_list = [["level"="1","name"="liming_l"],["level"="2","name"="ddd_l"],["level"="3","name"="sfsdfsd_l"]];

$cate_list = [["id"=1,"ico"="001","name"="liming_c"],["id"=2,"ico"="002","name"="ddd_c"],["id"=3,"ico"="003","name"="sfsdfsd_c"]];

foreach ($task_list as $item) {

foreach ($level_list as $ite) {

if ($item['level'] == $ite['level']){

$item['levelname'] = $ite['name'];

}

}

foreach ($cate_list as $it) {

if ($item['cid'] == $it['id']){

$item['name'] = $it['name'];

$item['ico'] = $it['ico'];

}

}

empty($item['name']) ? $item['name'] = $cate_list[0]['name'] :'';

empty($item['ico']) ? $item['ico'] = sp_config('web_logo') :'';

}

print_r($task_list);

Array ( [0] = Array ( [cid] = 1 [level] = 1 [name] = liming_c [levelname] = liming_l [ico] = 001 ) [1] = Array ( [cid] = 2 [level] = 2 [name] = ddd_c [levelname] = ddd_l [ico] = 002 ) [2] = Array ( [cid] = 3 [level] = 3 [name] = sfsdfsd_c [levelname] = sfsdfsd_l [ico] = 003 ) )

正常邏輯數(shù)組里的值是改變了的，如果沒改變這個(gè)需要查詢一下數(shù)組的值匹配了

php 操作數(shù)據(jù)庫的問題，打印的值顯示都正常，就是更改不了？

建議在10行（sqlsrv_query）后面增加下面的語句：

if( $data === false ) {

echo $sql;

die( print_r( sqlsrv_errors(), true));

}

主要是查看SQL查詢是否執(zhí)行成功，另外也可以把echo $sql放在執(zhí)行前，當(dāng)需要修改的數(shù)據(jù)不存在（0條修改）的時(shí)候sqlsrv_query執(zhí)行會(huì)成功。

php編寫修改用戶信息程序時(shí)，數(shù)據(jù)庫總是不能實(shí)現(xiàn)修改。

$userId是否有值，有沒有報(bào)錯(cuò)？

$sql?=?"update?`user`?set?`id`='".$userId."',`username`=".$username.",`password`=".$password.",`email`=".$email.",`idgroup`=".$idgroup."?where?id=".$userId."";

改成

$sql?=?"update?`user`?set?`username`=".$username.",`password`=".$password.",`email`=".$email.",`idgroup`=".$idgroup."?where?id=".$userId."";

試試
