What to do with array?

jnmunsey

Ok, I hit a Web Services server using SOAP which returned some data. Using a client script I found I got date that looks like this when using the print_r function:

(
[Category] => Array
(
[0] => Array
(
[ParentCategoryID] => 2
[ParentCategoryDesc] => CONCERTS
[ChildCategoryID] => 87
[ChildCategoryDesc] => 50s/60s ERA
[GrandChildCategoryID] => 25
[GrandChildCategoryDesc] => -
)

        [1] => Array
            (
                [ParentCategoryID] => 2
                [ParentCategoryDesc] => CONCERTS
                [ChildCategoryID] => 22
                [ChildCategoryDesc] => ALTERNATIVE
                [GrandChildCategoryID] => 25
                [GrandChildCategoryDesc] => -
            )
    )

)

the call I make to get this data is:
$result = $client->call('GetAllCategories', array('parameters' => $param), '', '', false, true);

and the to display it I used:
print_r($result);

Ok, now what? Forgive me I am an average PHP guy. I cannot figure out how to access the array and work with the data inside.

I guess I need some assistance pulling the data out of that array and then working with it. From there I am fine..

Thanks

for and foreach would work good here...

$count = sizeof($Category);
for($i=0;$i<$count;$i++)
{
  foreach($Category[$i] as $key=>$value)
    echo 'The value of  $Category[' . $i . '][\'' . $key . '\'] is: ' . $value . '<br />';
//note - there are 2 slashes that the website stripped...
//like so: ][(backslash)'' and '(backslash)'] is:
}

hope that helps

Thanks, I was just about to post that I had figured it out.

This is what I got:

for ($i = 0, $cnt = count($result['Category'],0); $i < $cnt; $i++) {

echo 'ParentCategoryID: ', $result['Category'][$i]['ParentCategoryID'], '<br>';
echo 'ParentCategoryDesc: ', $result['Category'][$i]['ParentCategoryDesc'], '<br>';
echo 'ChildCategoryID: ', $result['Category'][$i]['ChildCategoryID'], '<br>';
echo 'ChildCategoryDesc: ', $result['Category'][$i]['ChildCategoryDesc'], '<br>';
echo 'GrandChildCategoryID: ', $result['Category'][$i]['GrandChildCategoryID'], '<br>';
echo 'GrandChildCategoryDesc: ', $result['Category'][$i]['GrandChildCategoryDesc'], '<br><br><br>';
}

just a few notes

1) you generally dont want to put functions inside of a for loops conditional statement, especially ones like count() each time the loop reiterates, it has to recount the array thus taking up more processing time during execution....

2) you can simplify that loop big time with something like I did in my first post...

$category = $result['Category'];
$count = sizeof($category); 
for($i=0;$i<$count;$i++) 
{ 
  foreach($category[$i] as $key=>$value) 
    echo $key . ': ' . $value . '<br />'; 
}

[edit -- what's your fascination with commas also? I see you are using them instead of periods to concatenate? --]

should yield the same output as yours 😉

Some of that came from some other code...so learn as you go I suppose.. I didn't even notice the commas. I usually use periods myself, and would not normally put a function in there like that, but it was quick.

Thanks
