I have this php associative array.
array(
'Location_1' => 'Link_1',
'Location_2' => 'Link_2'
)
I would like to convert it into a json output using json_encode() that looks like this;
[{"Location_name":"Location_1","Link_name":"Link_1"},{"Location_name":"Location_2","Link_name":"Link_2"}]
How can this be done? The challenging part to me seems like how to add the Location_name and Link_name in front. Thank you very much.
<?php
// original array
$a = array(
'Location_1' => 'Link_1',
'Location_2' => 'Link_2'
);
// transform
$b = array();
foreach($a as $key=>$value) {
$b[] = array('Location_name'=>$key, 'Link_name'=>$value);
}
// output
echo json_encode($b);
?>
Result:
[{"Location_name":"Location_1","Link_name":"Link_1"},{"Location_name":"Location_2","Link_name":"Link_2"}]
You Can use StdClass anonymous Objects.
<?php
$newArray = array();
$array = array(
'Location_1' => 'Link_1',
'Location_2' => 'Link_2'
);
foreach ($array as $key => $value) {
$object = new StdClass();
$object->Location_name = $key;
$object->Link_name = $value;
$newArray[] = $object;
}
var_dump(json_encode($newArray));
So first things first:
convert it into a json output using json_encode() that looks like this
This is not possible. json_encode just encodes arrays to JSON, you need to do the formatting work yourself.
array_map should do the trick.
Try this:
$arr = array(
'Location_1' => 'Link_1',
'Location_2' => 'Link_2'
);
$output = array_map(
function( $key, $val ){
return array(
"Location_name" => $key,
"Link_name" => $val
);
}, array_keys( $arr ), $arr );
echo json_encode( $output );
