函数中的PHP数组

php arrays

函数中的PHP数组,php,arrays,Php,Arrays,在尝试将数组函数从一个php页面传递到另一个php页面时。page try.php具有实际功能 function someFunc() { include_once("includes/dbconnect.php"); $types = array(); $connect = TRUE; $dbconn = dbconnect($connect); if ($dbconn) { $sql = "select usertype, userdeptnum from bd.bdusers"

在尝试将数组函数从一个php页面传递到另一个php页面时。page try.php具有实际功能

function someFunc() {

include_once("includes/dbconnect.php");
$types = array();
$connect = TRUE;
$dbconn = dbconnect($connect);

if ($dbconn) {
    $sql = "select usertype, userdeptnum from bd.bdusers";

    $stmt = db2_prepare($dbconn, $sql);
    if ($stmt) {
        $result = db2_execute($stmt);
        if (!$result) {
            echo "exec errormsg: " . db2_stmt_errormsg($stmt);
        }

        while ($row = db2_fetch_assoc($stmt)) {
            $types[] = $row;

        }
    } else {
        echo "exec errormsg: " . db2_stmt_errormsg($stmt);
    }
    db2_close($dbconn);
} else {
    echo "faild " . db2_conn_errormsg();
}

return array($types);
}
如果我使用

 echo "<pre>";
 print_r($types);
 echo "</pre>";
但是当我在try2.php上传递这个函数时，同样的pre，print\r来看看我得到了什么，我得到了这个

function someFunc() {
    include_once("includes/dbconnect.php");
    $types = array();
    $connect = TRUE;
    $dbconn = dbconnect($connect);
    if ($dbconn) {
        $sql = "select usertype, userdeptnum from bd.bdusers";
        $stmt = db2_prepare($dbconn, $sql);
        if ($stmt) {
            $result = db2_execute($stmt);
            if (!$result) {
                echo "exec errormsg: " . db2_stmt_errormsg($stmt);
            }
            while ($row = db2_fetch_assoc($stmt)) {
                $types[] = $row;

            }
        } else {
        echo "exec errormsg: " . db2_stmt_errormsg($stmt);
    }
    db2_close($dbconn);
    } else {
        echo "faild " . db2_conn_errormsg();
    }
    return $types; //<==
}
它是数组中的一个数组。我尝试使用foreach和for循环回显数组，但我总是得到未定义的索引或数组到字符串的转换，它只是打印出“array”。
我做错了什么？

因为您返回了
数组（$types）。返回
$types
而不是
数组（$types）

我更改了这一行并刷新了try2.php，使用pre我得到了外观正确的数组，但是foreach给了我这个错误“注意：第17行数组上的/www/webvr6/try2.php中的数组到字符串转换”我试图用这个数组填充一个表。有更好的方法吗？我更改了这一行并刷新了try2.php，使用pre我得到了外观正确的数组，但是foreach给了我这个错误“注意：第17行数组上的/www/webvr6/try2.php中的数组到字符串的转换”我试图用这个数组填充一个表。有更好的方法吗？我更改了这一行并刷新了try2.php，使用pre我得到了外观正确的数组，但是foreach给了我这个错误“注意：第17行数组上的/www/webvr6/try2.php中的数组到字符串的转换”我试图用这个数组填充一个表。有更好的方法吗？我更改了这一行并刷新了try2.php，使用pre我得到了外观正确的数组，但是foreach给了我这个错误“注意：第17行数组上的/www/webvr6/try2.php中的数组到字符串的转换”我试图用这个数组填充一个表。有更好的方法吗？
