array_push

[Anon]

I need push a hash into array.
eg.

$a = "value";
$b = array();
array_push ($b['key'],$a); //Not working
echo "key>".$b['key']."<";

Prints:
key><

what is the right way to do so?
thanx

<?
$a = 'value';
$b = array ();
array_push ($b, $a);
?>

this will at $a to the end of the $b array, is that what you want to do?

I would like to have a result similar to opperation:
$b['key']= 'value';

I did try:
$k = "key";
$a = "value";
$b = array();
array_push ($b[$k],$a); //Not working

Should add $a to the end of array $b[$k] and should be the same as:
$b[$k] = $a;

But it is not :-(

your code is failing because the first argument to array_push() must be an array. $b[$k] is not an array, it is one just one index of the $b array.

The array_push() function is for adding multiple items to the end of an array. If all you need to do is add one item, then you don't need array_push(), just do:

$b[]= 'value';

array_push() can take other arrays as arguments and the result will be a 2D array:

$array1 = array (
'1' => 'one',
'2' => 'two',
'3' => 'three',
'4' => 'four',
'5' => 'five'
);

$array2 = array (
'6' => 'six',
'7' => 'seven',
'8' => 'eight',
'9' => 'nine',
'10' => 'ten'
);

array_push ($array1, $array2);

Now, the sixth index of $array1 will be another array ($array2) making $array1 two dimensional.

If you just want to combine 2 arrays (tack one on the end of another) then just do:

$array3 = $array2 + $array1;

This is better than array_merge() because it does not mess up you keys names.

Thanx!
I got the solution.
