Array help

[Canman2005]

Hi all

 

I have an array set under

 

$_SESSION['items']

 

so if I do a

 

print_r($_SESSION['items']);

 

then I get

 

( [1] => 4 [45] => 2 )

 

what I want to do is implode that array so that I get an output that looks like

 

1,45

 

but I cannot figure it out.

 

If I use

 

print implode(",", $_SESSION['items']);

 

then that outputs

 

4,2

 

but I want it to output

 

1,45

 

instead

 

any ideas?

 

thanks

Try...

 

$output_string = '';
$start = TRUE;
foreach ($_SESSION['items'] as $key => $value) {
    if (!$start) 
        $output_string .= ', ';
    else
       $start = FALSE;
    $output_string .= $key;
}

// Do whatever you want with $output_string

$imp=implode(",",array_keys($array));

or just do

$keys = array_keys($_SESSION['items']);

$str = implode($keys, ',');

 

array_keys():

coooool, thanks for that everyone

 

I wonder if you could help me further

 

Is it possible to pull a single value from an array?

 

Let me explain.

 

My array currently looks like

 

( [1] => 4 [45] => 2 )

 

so with the above

 

45 is linked to 2  ([45] => 2)

 

and

 

1 is liked to 4  ([1] => 4)

 

so is it possible for example, to supply var such as

 

$var = 45

 

and run something so that it grabs the value

 

2

 

or if I supplied

 

$var = 1

 

then it would allow me to grab value

 

4

 

any help would be fab

 

thanks all

yes, just use the square bracket operator to supply whatever index you want

$key = 45
echo $_SESSION['item'][$key];//echos 2

//store the 2 from $_SESSION['item'] in a variable
$two = $_SESSION['item'][$key];

//alternatively, this will also work
$two = $_SESSION['item'][45];
