$i=0;
$array=array("one","two");
foreach($array as &$point)
{
$point[$i]=array($point[$i], $i);
$i++;
}
var_dump($array);
yields:
array(2) { [0]=> string(3) "Ane" [1]=> &string(3) "tAo" }
I was expecting something more like:
[0]=> [0]=> "one" [1]= 1
[1]=> [0]=> "two" [1]= 2
Am I doing the inner block of the foreach wrong, or is there another method I should be using to go from a single to a 2D array?
You mean like this:
$i=1;
$array=array("one","two");
foreach($array as $j => $point)
{
$array[$j]=array($point, $i);
$i++;
}
var_dump($array);
Outputs:
array(2) {
[0]=>
array(2) {
[0]=>
string(3) "one"
[1]=>
int(1)
}
[1]=>
array(2) {
[0]=>
string(3) "two"
[1]=>
int(2)
}
}
$array = array("one","two");
foreach($array as $i => &$point)
{
$point = array($point, $i + 1);
}
var_dump($array);
There were several errors in your code:
$point$point, not $point[$i]Array to string conversion error for your code.You may use this to define a two dimensional array in PHP
$array = array(
array(0, 1, 2),
array(3, 4, 5),
);
