How to add a new element to a 2D array ?

[tmyonline]

Hi guys:

 

I have a 2D associative array in a foreach loop like this:

 

foreach (boolean expression) {

  $myArray = array (

    "element_1" => array("x1", "y1", "z1")

  );

}

 

Everytime through the loop, I want to add the "element_i" associated with values (xi, yi, and zi) to the $myArray.  At the moment, what happens is that the $myArray does not expand because the element_1 and (x1, y1, and z1) are being overwritten by the new values.  Consequently, when the loop finishes, the $myArray is the same as it was.  I want it to be such that, after 2 iterations, it would add two rows like this:

 

foreach (boolean expression) {

  $myArray = array (

    "element_1" => array("x1", "y1", "z1"),

    "element_2" => array("x2", "y2", "z2"),

    "element_3" => array("x3", "y3", "z3")

  );

}

 

instead of overwriting the element_1 and (x1, y1, z1).  What is your recommendation ?  Thanks.

Personally I'd just add a counter.  Not sure if there is an easier way but I know it would work.

 

$counter=0;

foreach (boolean expression) {

  $myArray = array (

    "element_" . $counter => array("x1", "y1", "z1"),

  );

  $counter++;

}

try

<?php
for ($x=0;$x<9;$x++) {
$i++;
  $myArray['element_'.$i] = array ("x$i", "y$i", "z$i");
}
print_r($myArray);
?>
