Simple array access and manipulation methods - php

Question

Hy, I designed an array, and I need some help because I've got aaaloot of headaches. Can anyone give me a simple idea how to work with this in a simple way?
Most of the errors when I try to add some values in my array are array offset error.
My array:
$info = array
(
"id" => "",
"city" => "",
"university" => array
(
"name" => "",
"address" => "",
"phone" => "",
"fax" => "",
"email" => "",
"website" => "",
"type" => "",
"faculty" => array
(
"name" => "",
"adress" => "",
"phone" => "",
"fax" => "",
"email" => "",
"website" => "",
"type" => "",
)
)
);
CODE:
<?php
// HTML DOM PARSER LIBRARY
include('hdp.php');
//error_reporting(false);
/*
* Returns an array with field associative name and
* extracted value, using a specified delimiter.
*/
function extractField($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]);
}
}
return false;

Answer 1

You are accessing the array the wrong way in those calls:
$info[$a]["city"] = $ftext;
$info[$a]["city"][$b]['university']['name'] = $ftext;
Correct would be:
$info["city"] = $ftext;
$info["city"]['university']['name'] = $ftext;
It seems you want to handle multiple $info-arrays. For this you have to create an array of those info-arrays.

Final and working code, if anyone fiind this usefull:
// HTML DOM PARSER LIBRARY
include('hdp.php');
error_reporting(true);
// Session to know what last city was
session_start();
if (!$_SESSION['LAST']) $_SESSION['LAST'] = NULL;
/*
* Returns an array with field associative name and
* extracted value, using a specified delimiter.
*/
function extractField($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);

{
