2d Array Use

[robinirwin]

I am trying to read from a txt file and then exlplode the contents of each line to remove the delimiter to form a 2d array so I may reference individual entries by $Data[$num][$num] e.g.

Third one |first_radio|[e-mail]

exploded to get each entry individually. I am using the folowing code:

$lines = file($file_name);  // form array of lines

foreach($lines as $Key => $Val) { 

  $Data[$Key][] = explode("|", $Val);
  echo "Line ".$Key." :".$Val."<br>";  // just to check lines are correct
  }

echo "<br>Test Line Entry before implementing a loop:<br>";
echo "Answer(s) 1: " . $Data[0][0]."<br>"; 
echo "Answer 2: " . $Data[0][1]."<br>";
echo "Answer 3: " . $Data[0][2]."<br>";

I keep getting the output 'Answer(s) 1: Array'.

Can anyone please suggest my error in attempting this approach?

try to use this code instead in your foreach()-loop:

foreach($lines as $Key => $Val)
{
	$NewVal = explode("|", $Val); 
	foreach($NewVal as $SubKey => $SubVal)
		$Data[$Key][$SubKey] = $SubVal;
}
