Merging Arrays

bike5

I need a little help merging arrays. I have two arrays that are populated dynamically and I need to merge them so that one array is linked under an element of the other array in order during a loop. Here is my code:

$t = 0;
$c = 0;
for($x=0;$x < $len;$x++)
{
	if($x % 2 == 0)
	{
		$table[$t] = $new[$x];
		$t++;
	}else
	{
		$col[$c] = $new[$x];
		$col_e = explode(',',$col[$c]);
//I need $table[$t][$col_e] format
		$c++;
	}

}

I need a new array to contain $table[0][$col_e] format and build it during the loop so col_e is placed in the correct spot. The $new[] array is a single array I am pulling the table and col values from dynamically. How can I do this merge? I have tried many ways and could not get the correct format within the new array. If I need to explain anything futher please let me know. Thank you for your time.

Could you give us an example of what you are starting with, and what you want the final (merged) array to look like?

$new[0] = 'direction';
$new[1] = 'd1,d2,d3,d4,d5,d6';
$new[2] = 'char';
$new[3] = 'c1,c2,c3,c4,c5,c6,c7,c8,c9';
$new[4] = 'ping';
$new[5] = 'p1,p2';

This is the structure of the original array I am working with. I need to break everyother one up into an array based on the "," and have that array be under the main array above it. So I would end up with.

$table[direction][d1]
$table[direction][d2]
$table[direction][d3]
$table[direction][d4]
$table[direction][d5]
$table[direction][d6]
$table[char][c1]
$table[char][c2]
$table[char][c3]
ect..

Thank you.

I don't like counting through arrays. Here's my solution:

$toplevel = true;
$table = array();

foreach ($new as $key => $val) {
  if ($toplevel) {
    $firstkey = $val;
  } else {
    $arraylist = explode(',', $val);
    foreach ($arraylist as $arrayval) {
      $table[$firstkey][$arrayval] = NULL;
    }
  }
  $toplevel = !$toplevel;
}

this exact code should produce:

$table[direction][d1] = NULL
$table[direction][d2] = NULL
$table[direction][d3] = NULL
$table[direction][d4] = NULL
$table[direction][d5] = NULL
$table[direction][d6] = NULL
$table[char][c1] = NULL
$table[char][c2] = NULL
$table[char][c3] = NULL

Now, if what you meant was that you need an array like this:

$table[direction][0] = 'd1';
$table[direction][1] = 'd2';
$table[direction][2] = 'd3';
$table[direction][3] = 'd4';
$table[direction][4] = 'd5';
$table[direction][5] = 'd6';
$table[char][0] = 'c1';
$table[char][1] = 'c2';
$table[char][2] = 'c3';

Let me know. This is actually easier to do than the other, but, from the example you gave, the first solution should provide you with what you need.

Thanks for the reply, however I had to meet a deadline today so I re-wrote my script to handle my two arrays serperatly without having to merge them which actually turned out easier then I thought. I will review your code and most likely use it for future refence so thank you again. Oh and yes I did "mean" the second way "$table[direction][5] = 'd6';
$table[char][0] = 'c1';".. I need to work on my explaining skills. Thanks 😃
