for some reason, the array i made only queries out the last value in the foreach statement like example below
$message = array('hello'=>'there');
$message = array('hello'=>'there');
$message = array('hello'=>'there');
$message = array('hello'=>'there');
foreach ($message as $key => $value) {
echo $key." ".$value;
}
it only queries out hello there once. what am i doing wrong ???
because your array only has one key value pair. $message = is just overwriting the previously defined $message.
So what you apparently want is a 2-dimension array:
$message = array(
array('hello'=>'there'),
array('hello'=>'there'),
array('hello'=>'there'),
array('hello'=>'there')
);
So let me just get this straight so I can have a better understanding of arrays. Are you saying that the varible $message is actually a key value ?? I thought it was just a varible that store multiple key values. so doing this
$message = array('hello' => 'value');
is the samething as doing this
$hello = array('value')
except its encapsulated inside of the varible $message ?????
Now this the code im using
$message = array(array('hello'=>'there'));
$message = array(array('hello2'=>'there'));
$message = array(array('hell03'=>'there'));
$message = array(array('hello4'=>'there'));
foreach ($message as $key => $value) {
echo $key." ".$value;
}
but this is the output
0 : Array 0 Array
.. but you need to do is to do something like NogDog suggested:
$message = array(array('hello'=>'there'),
array('hello'=>'there'),
array('hello'=>'there'),
array('hello'=>'there'));
foreach ($message as $key => $value) {
//echo $key." ".$value;//this will list out only first array dimension,
//but to get an actual values you need to scope the second dimension like this:
while(list($k,$v) = each($value)){
echo "$k $v<br />";
}
}
Your way of creating array only rewrites array so you end up with one member in the end and it is in second dimension...
Hence the 0 Array... That just means that you have another array stashed under the key 0... Are array clearer now?
Yes I understand now BUT....
what if I have a Class that contains a array... and the only way you can add a key and value to this array is through a function.
How would i go about doing that ? I just cant leave the array parenthesis open.
You always can create a two dimensional array this way as well:
$message[] = array('hello'=>'there');
$message[] = array('hello'=>'there');
$message[] = array('hello'=>'there');
$message[] = array('hello'=>'there');
$message[] = array('hello'=>'there');
This way you would get the same array as in the previous example...
ok thanks!!
