[RESOLVED] Multidimensional array problems

Staggy11

I'm trying to use a multi-dimensional array to echo three pieces of information; 'date', 'name' and 'speech'.
I use 'date' (which is a timestamp) as the main index key, and then want to have 'name' and 'speech' stored underneath it. I.e.

$data = array('124674517235' => array('name'=> "John", 'speech'=>"Hello"));

However, I am not sure on how to get the information out using foreach. My output needs to be

'date':'name' - 'speech'
'date':'name' - 'speech'
'date':'name' - 'speech'

and so on.

The code that I came up with was

foreach ($speech_array as $key) {
if ($key <= $lastactive){
unset($speech_array[$key]);	
}
if ($key > $lastactive) {
echo date('H:i:s', $key); 
echo " : ";
foreach ($key as $name => $val) {
echo $val;
}
echo " - ";
foreach ($key as $speech => $value) {
echo "\"";
echo $value;
echo "\"";
}
echo '<BR>';
}
}

but it gave numerous errors including

Warning: date() expects parameter 2 to be long, string given in /maptest.php on line 128

and

Invalid argument supplied for foreach()

Can anyone show me where I am going wrong?

Use one foreach for the main array, with a second nested foreach to loop through the elements of the subarrays (much like, but not quite like, what you're already doing):

foreach ($main_array as $key => $sub_array) {
    echo date('H:i:s', $key) . ' : ';
    foreach ($sub_array as $sub_value)
        echo $sub_value[$name] . ' - ' . $sub_value['speech'] . '<br />';
    }
}

The date() parameter error is caused by putting the timestamp in quotes. A Unix timestamp is an integer, not a string.

I see. So if I would the code for adding a new section be?:

$time=time();
	$new=$_POST['speech'];
          while ($row = mysql_fetch_array($query))
                 { 
                  $uns=unserialize($row['speech']);
                  $uns[$time]["speech"] = $new;
                  $uns[$time]["name"] = $name;
                                   } //end while

I'm now getting the error

Warning: Invalid argument supplied for foreach() in /maptest.php on line 131

Line 131 is

foreach ($sub_array as $sub_value){

out of

foreach ($speech_array as $key => $sub_array) {
   if ($key <= $lastactive){
        unset($speech_array[$key]);	
        }
if ($key > $lastactive) {
    echo date('H:i:s', $key) . ' : ';
    foreach ($sub_array as $sub_value){
        echo $sub_value[$name] . ' - ' . $sub_value['speech'] . '<br />';
    }
} }

Any help?

foreach ($speech_array as $key => $value) { 
    if ($key <= $lastactive) { 
        unset($speech_array[$key]);
    } else { 
        echo date('H:i:s', $key) . ' : '; 
        echo $value['name'] . ' - ' . $value['speech'] . '<br />'; 
    } 
}

Cheers! That works perfectly!
