Long time, everyone! Foreach loop question

[AV1611]

First, long time no see for those who remember me

 

I have a question about foreach loops and arrays.

 

I know how to foreach the elements of an array

 

$array=array("a","b","C");

$i=0;

$c=count($array);

while($i < $c){

//do something with element $array[$i]

$i++;

}

 

that's just an example but I want to be able to do it with a multi array:

 

$array=

a[0]item

a[1]item

a[2]item

b[0]item

b[1]item

b[2]item

 

so I want to foreach the $array[]

then while that's going I want to foreach the $array[][] within that.

 

foreach $array[]{

    foreach $array[][]{

      }

}

 

Not sure how to do that.

 

wow, hope that makes sense

A basic example

$array = array();
$array[] = array('a', 'b', 'c');
$array[] = array('e', 'f', 'g');

// convert multi-dimensional array above into a simple table
echo '<table border=1>';
foreach($array as $sub_array)
{
    echo '<tr>';
    foreach($sub_array as $item)
   {
        echo "<td>$item</td>";
   }
   echo '</tr>';
}
echo '</table>';

If I am not mistaking your array kind of looks like this?

 

<?
$array[a][1] = 'item1';
$array[a][2] = 'item2';
$array[a][3] = 'item3';
$array[b][1] = 'itemb1';
$array[b][2] = 'itemb2';
$array[b][3] = 'itemb3';
$array[c][1] = 'itemc1';
$array[c][2] = 'itemc2';
$array[c][3] = 'itemc3';

 

I think you want to do is

<?
foreach($array as $key => $val) {
   echo "Currently ".$key."<br>";
   foreach($val as $k=>$v) {
       echo "$k => $v <br/>";
   }
   echo "<br>";
}
?>

 

This will output

Currently a

1 => item1

2 => item2

3 => item3

 

Currently b

1 => itemb1

2 => itemb2

3 => itemb3

 

Currently c

1 => itemc1

2 => itemc2

3 => itemc3

One last question before I can mark my problem solved and I'll post my code when I'm done to help others...

 

In the multi array, the sub arrays are numbered.  The array themselves are not numbers

 

$array['Name'][0]

$array['Name'][1]

$array['Name2'][0]

$array['Name2'][1]

...

and so on

 

I know that $array['Name'] is the name of the element, but is there a way to echo the element name?

N/M

 

Found it...

 

foreach ($array as $k => $v) {

  echo "$k<br />";

}
