array in array but not wanted

[freelance84]

OK apologies for the length of this one.

 

Below is some php code which generates all the possible combinations from the result of user input in a table using radio buttons.

 

An example of the $_POST result from the user selecting one of all of the radio buttons is as follows:

Array ( [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 [all_possible] => All Possible Results )

1-7 are the names of the radio buttons, and all_possible is the name of one of the buttons in the form.

 

The form relates to a table which looks something like:

a_number    |g_number    |option_number    |comment    |

101at1

201sldfhjlsd

301at3a

The table goes on...

 

The php code:

if (isset($_POST['all_possible']))
{
//getting users matrix answers
$r_number = array();	//[0]=at1 [1]=at2....
for($an = 1 ; $an < 8 ; ++$an)
	{
		$g_number = get_post($an);
		array_push($r_number, $g_number);
	}
//getting the number of options per g
$count = array();
for($op = 1 ; $op < 8 ; ++$op)
	{
		$rn = $op - 1;
		$query_option_quant = "SELECT option_number FROM matrix WHERE a_number='$op' AND g_number='$r_number[$rn]'";
		$option_result = mysql_query($query_option_quant);
		$rows = mysql_num_rows($option_result);
		array_push($count,$rows);
	}
//getting all possible combinations
$all_combinations = array();
for($a1 = 0 ; $a1 < $count[0] ; ++$a1)
	{
		for($a2 = 0 ; $a2 < $count[1] ; ++$a2)
			{
				for($a3 = 0 ; $a3 < $count[2] ; ++$a3)
					{
						for($a4 = 0 ; $a4 < $count[3] ; ++$a4)
							{
								for($a5 = 0 ; $a5 < $count[4] ; ++$a5)
									{
										for($a6 = 0 ; $a6 < $count[5] ; ++$a6)
											{
												for($a7 = 0 ; $a7 < $count[6] ; ++$a7)
													{
														array_push($all_combinations,$a1.",".$a2.",".$a3.",".$a4.",".$a5.",".$a6.",".$a7);
													}
											}
									}
							}
					}
			}
	}
$counted = count($all_combinations);
for($ctd = 0 ; $ctd < $counted ; ++$ctd)
	{
		$combination = explode(",",$all_combinations[$ctd]);
		for($atn = 1 ; $atn < 8 ; ++$atn)
			{
				$rpn = $atn - 1;
				$query_get_comment = "SELECT comment FROM matrix WHERE a_number = '$atn' AND g_number = '$r_number[$rpn]'";
				$get_result = mysql_query($query_get_comment);
				$number_comments = mysql_num_rows($get_result);
				$comment = array();     //this is array in question
				for($i = 0 ; $i < $number_comments ; ++$i)
					{
						$com = mysql_fetch_row($get_result);
						array_push($comment,$com);
					}
				echo $rpn."<br />";
				print_r($comment);
				echo "<br />";
			}
		echo "<br />";
		echo "<br />";
	}
}

 

 

The result of the above is:

0

Array ( [ 0] => Array ( [ 0] => at1 ) )

1

Array ( [ 0] => Array ( [ 0] => sldfhjlsd ) )

2

Array ( [ 0] => Array ( [ 0] => at3a ) )

3

Array ( [ 0] => Array ( [ 0] => at4a ) )

4

Array ( [ 0] => Array ( [ 0] => at5a ) )

5

Array ( [ 0] => Array ( [ 0] => at6a ) )

6

Array ( [ 0] => Array ( [ 0] => at7a ) [1] => Array ( [ 0] => at7b ) )

 

 

0

Array ( [ 0] => Array ( [ 0] => at1 ) )

1

Array ( [ 0] => Array ( [ 0] => sldfhjlsd ) )

2

Array ( [ 0] => Array ( [ 0] => at3a ) )

3

Array ( [ 0] => Array ( [ 0] => at4a ) )

4

Array ( [ 0] => Array ( [ 0] => at5a ) )

5

Array ( [ 0] => Array ( [ 0] => at6a ) )

6

Array ( [ 0] => Array ( [ 0] => at7a ) [1] => Array ( [ 0] => at7b ) )

 

 

 

The array in question I have commented out in the php code above. I can't understand why it isn't just creating a single dimension array?

I can't believe it. After typing out all that thread I found i'de missed off a tiny little thing in my code:

 

$comment = array();
				for($i = 0 ; $i < $number_comments ; ++$i)
					{
						$com = mysql_fetch_row($get_result);
						array_push($comment,$com[0]);   // i left out the [0]
					}

 

Now it works
