How To Make Associative Array Into Numerical Array ?

Hello,

Is it not true that, parse_url() extract all the properties of a url and save each property into array ?
By properties I talking about:
scheme
host
port
user
pass
path
query
fragment

I reckon, the array actually looks like this:

[“0″=>”scheme”,”1″=>”host”,”2″=>”port”,”3″=>”user”,”4″=>”pass”,”5″=>”path”,”6″->”query”,”7″=>”fragment”]

True or not ? Tell me this!
Anyway, I now adding all this array to $url_properties = array();
To echo each value of the array. Like this ofcourse …

““
<?php

$url = ‘http://user:[email protected]/path.php?query_string=value#fragment1’;

print_r(parse_url($url)); echo ‘<br>’;
echo ‘<br>’;
var_dump(parse_url($url)); echo ‘<br>’;

$url_properties = array();
$url_properties = parse_url($url);

echo $url_properties[0];
echo $url_properties[1];
echo $url_properties[2];
echo $url_properties[3];
echo $url_properties[4];
echo $url_properties[5];
echo $url_properties[6];
echo $url_properties[7];

?>
““

But I get error:
**Notice: Undefined offset: 0 in C:xampphtdocs...php on line 12
Notice: Undefined offset: 1 in C:xampphtdocs...php on line 13
Notice: Undefined offset: 2 in C:xampphtdocs...php on line 14
Notice: Undefined offset: 3 in C:xampphtdocs...php on line 15
Notice: Undefined offset: 4 in C:xampphtdocs...php on line 16
Notice: Undefined offset: 5 in C:xampphtdocs...php on line 17
Notice: Undefined offset: 6 in C:xampphtdocs...php on line 18
Notice: Undefined offset: 7 in C:xampphtdocs...php on line 19**

Why is this ?

This working fine, though….

““
<?php

$url = ‘http://user:[email protected]/path.php?query_string=value#fragment1’;

print_r(parse_url($url)); echo ‘<br>’;
echo ‘<br>’;
var_dump(parse_url($url)); echo ‘<br>’;

$url_properties = array();
$url_properties = parse_url($url);

foreach($url_properties AS $property)
{
echo $property;
}

?>
““

I get echoed:
**httpdomain.comuserpassword/path.phpquery_string=valuefragment1**

This is proof that the $url_properties array is not empty.
So why the error on my first code when trying to echo each of the value of this array ? Strange!

EDIT:
I have figured my error. The array is associative array and so this is working:

““
echo $url_properties[‘scheme’];
echo $url_properties[‘user’];
echo $url_properties[‘pass’];
echo $url_properties[‘host’];
echo $url_properties[‘port’];
echo $url_properties[‘path’];
echo $url_properties[‘query’];
echo $url_properties[‘fragment’];
““

But what few lines of code should I add so that even the following works and does not give undefined offset error ?

““
echo $url_properties[0];
echo $url_properties[1];
echo $url_properties[2];
echo $url_properties[3];
echo $url_properties[4];
echo $url_properties[5];
echo $url_properties[6];
echo $url_properties[7];
““
