嗨，我设计了一个数组，我需要一些帮助，因为我很头疼。谁能给我一个简单的想法如何以简单的方式使用它？

当我尝试在我的数组中添加一些值时，大多数错误都是数组偏移错误。

我的数组：

$info = array
(
    "id" => "",
    "city" => "",
    "university" => array
    (
        "name"    => "",
        "address"  => "",
        "phone"   => "",
            "fax"     => "",
        "email"   => "",
        "website" => "",
        "type"    => "",
        "faculty" => array
        (
            "name"    => "",
            "adress"  => "",
            "phone"   => "",
            "fax"     => "",
            "email"   => "",
            "website" => "",
            "type"    => "",
        )
    )
);

代码：

<?php
// HTML DOM PARSER LIBRARY
include('hdp.php');

//error_reporting(false);

/*
 * Returns an array with field associative name and
 * extracted value, using a specified delimiter.
 */

function extractField($str, $delim)
{
        $val = '';
    // All possible fields
    $posFlds = array
    (
        'Adresa'  => 'address',
            'Telefon' => 'phone',
        'Fax'     => 'fax',
        'Email'   => 'email',
        'Website' => 'website',
        'Tip'     => 'type'
    );

    foreach($posFlds as $fldName => $assocName)
    {
        if(strstr($str,$fldName))
        {
            $val = @explode($delim,$str);
            if (!$val[1])
            {
                    print 'Delimiter `'.$delim.'` not found!';
                    return false;
                }
                return array($assocName, $val[1]);
            }
        }

您在这些调用中以错误的方式访问数组：

$info[$a]["city"] = $ftext;
$info[$a]["city"][$b]['university']['name'] = $ftext;

正确的是：

$info["city"] = $ftext;
$info["city"]['university']['name'] = $ftext;

看来你想处理多个$info-arrays。为此，您必须创建这些信息数组的数组。

最终和工作代码，如果有人发现这个有用：

// Session to know what last city was
session_start();
if (!$_SESSION['LAST']) $_SESSION['LAST'] = NULL;

/*

 * extracted value, using a specified delimiter.
 */

function extractField($str, $delim)
{
    $val = '';
    // All possible fields
    $posFlds = Array
    (
        'Adresa'  => 'address',
        'Telefon' => 'phone',
        'Fax'     => 'fax',
        'Email'   => 'email',
        'Website' => 'website',
