I only want to output an array, first look at my code
CODE:
$shopping = array();
$shopping["john"] = "notebook1";
$shopping["john"] = "notebook2";
$shopping["doe"] = "notebook3";
echo '<pre>';
print_r($shopping);
echo '</pre>';
OUTPUT
Array
(
[john] => notebook2
[doe] => notebook3
)
But I want my output to be like this:
Array('john'=>array('notebook1','notebook2'),'doe'=>'notebook3');
How Can I achieve this?
You need to add []= not just = try this :
$shopping = array();
$shopping["john"][] = "notebook1";
$shopping["john"][] = "notebook2";
$shopping["doe"][] = "notebook3";
echo '<pre>';
print_r($shopping);
echo '</pre>';
Just need to assign $shopping["john"] to an array.
$shopping["john"] = array("notebook1", "notebook2");
$shopping["doe"] = "notebook3";
Actually, $shopping["john"] is a String.You need to declare it as an array. You can create your main array all in one:
$shopping = array(
"john" => array(
"notebook1",
"notebook2"
),
"doe" => "notebook3"
);
If using PHP 5.4 you can use the short array syntax:
$shopping = [
"john" => [
"notebook1",
"notebook2"
],
"doe" => "notebook3"
];
With this syntax you can use the shorthand to add an item to an array:
$shopping["john"][] = "notebook4";
/*
RESULT:
[john] => Array
(
[0] => notebook1
[1] => notebook2
[2] => notebook4
)
*/
