How to print arrays with square brackets instead of curly brackets in Laravel?
I have this piece of code in my laravel controller and it prints an array as below: Iitems is a collection.
$i = [];
foreach($items as $item) {
$i['grid'][$item->color]['color'] = $item->color;
$item_list['grid'][$item->color]['size_grid'][$item->size_no] = [
'size_no' => $item->size_no,
'size_description' => $item->size_desc,
'on_hand' => $item->on_hand,
];
}
Output:
"grid": {
"VELBL": {
"color": "VELBL",
"size_grid": {
"3": {
"size_no": 3,
"size_description": "MEDIUM",
"on_hand": "0"
},
"5": {
"size_no": 5,
"size_description": "X LARGE",
"on_hand": "0"
},
"4": {
"size_no": 4,
"size_description": "LARGE",
"on_hand": "0"
},
"1": {
"size_no": 1,
"size_description": "X SMALL",
"on_hand": "0"
},
"2": {
"size_no": 2,
"size_description": "SMALL",
"on_hand": "0"
}
}
},
"BLUAS": {
"color": "BLUAS",
"size_grid": {
"3": {
"size_no": 3,
"size_description": "MEDIUM",
"on_hand": "0"
},
"1": {
"size_no": 1,
"size_description": "X SMALL",
"on_hand": "0"
},
"2": {
"size_no": 2,
"size_description": "SMALL",
"on_hand": "0"
},
"4": {
"size_no": 4,
"size_description": "LARGE",
"on_hand": "0"
},
"5": {
"size_no": 5,
"size_description": "X LARGE",
"on_hand": "0"
}
}
},
"MHGR": {
"color": "MHGR",
"size_grid": {
"1": {
"size_no": 1,
"size_description": "X SMALL",
"on_hand": "0"
},
"2": {
"size_no": 2,
"size_description": "SMALL",
"on_hand": "0"
},
"3": {
"size_no": 3,
"size_description": "MEDIUM",
"on_hand": "0"
},
"4": {
"size_no": 4,
"size_description": "LARGE",
"on_hand": "0"
},
"5": {
"size_no": 5,
"size_description": "X LARGE",
"on_hand": "0"
}
}
}
}
This prints the result with curly brackets, but I need this to be print with square brackets. How can I achieve this? If I change my code it's not printing all necessary data, how can I print this same set of data with square brackets as below:
Expected output:
"grid": [
"VELBL": {
"color": "VELBL",
"size_grid": [
"3": {
"size_no": 3,
"size_description": "MEDIUM",
"on_hand": "0"
},
"5": {
"size_no": 5,
"size_description": "X LARGE",
"on_hand": "0"
},
"4": {
"size_no": 4,
"size_description": "LARGE",
"on_hand": "0"
},
"1": {
"size_no": 1,
"size_description": "X SMALL",
"on_hand": "0"
},
"2": {
"size_no": 2,
"size_description": "SMALL",
"on_hand": "0"
}
]
},
"BLUAS": {
"color": "BLUAS",
"size_grid": [
"3": {
"size_no": 3,
"size_description": "MEDIUM",
"on_hand": "0"
},
"1": {
"size_no": 1,
"size_description": "X SMALL",
"on_hand": "0"
},
"2": {
"size_no": 2,
"size_description": "SMALL",
"on_hand": "0"
},
"4": {
"size_no": 4,
"size_description": "LARGE",
"on_hand": "0"
},
"5": {
"size_no": 5,
"size_description": "X LARGE",
"on_hand": "0"
}
]
},
"MHGR": {
"color": "MHGR",
"size_grid": [
"1": {
"size_no": 1,
"size_description": "X SMALL",
"on_hand": "0"
},
"2": {
"size_no": 2,
"size_description": "SMALL",
"on_hand": "0"
},
"3": {
"size_no": 3,
"size_description": "MEDIUM",
"on_hand": "0"
},
"4": {
"size_no": 4,
"size_description": "LARGE",
"on_hand": "0"
},
"5": {
"size_no": 5,
"size_description": "X LARGE",
"on_hand": "0"
}
]
}
]
Please, someone, help me here as am new to the technology. Thanks in advance.
Update: By adding this line of code, now this prints the grid array with square brackets, but the array inside it, size_grid not with square brackets, how can I print size_grid array also with square brackets?
$item_list['grid'] = array_values($item_list['grid']);
Output:
"grid": [
{
"color": "VELBL",
"size_grid": {
"3": {
"size_no": 3,
"size_description": "MEDIUM",
"on_hand": "0"
},
"5": {
"size_no": 5,
"size_description": "X LARGE",
"on_hand": "0"
},
"4": {
"size_no": 4,
"size_description": "LARGE",
"on_hand": "0"
},
"1": {
"size_no": 1,
"size_description": "X SMALL",
"on_hand": "0"
},
"2": {
"size_no": 2,
"size_description": "SMALL",
"on_hand": "0"
}
}
},
{
"color": "BLUAS",
"size_grid": {
"3": {
"size_no": 3,
"size_description": "MEDIUM",
"on_hand": "0"
},
"1": {
"size_no": 1,
"size_description": "X SMALL",
"on_hand": "0"
},
"2": {
"size_no": 2,
"size_description": "SMALL",
"on_hand": "0"
},
"4": {
"size_no": 4,
"size_description": "LARGE",
"on_hand": "0"
},
"5": {
"size_no": 5,
"size_description": "X LARGE",
"on_hand": "0"
}
}
},
{
"color": "MHGR",
"size_grid": {
"1": {
"size_no": 1,
"size_description": "X SMALL",
"on_hand": "0"
},
"2": {
"size_no": 2,
"size_description": "SMALL",
"on_hand": "0"
},
"3": {
"size_no": 3,
"size_description": "MEDIUM",
"on_hand": "0"
},
"4": {
"size_no": 4,
"size_description": "LARGE",

},
"5": {
"size_no": 5,
"size_description": "X LARGE",

}
}
}

To obtain a square bracketed result within grid, the simple solution would be something like this:
// your existing code
$i = [];
foreach($items as $item) {
$i['grid'][$item->color]['color'] = $item->color;
$item_list['grid'][$item->color]['size_grid'][$item->size_no] = [
'size_no' => $item->size_no,
'size_description' => $item->size_desc,
'on_hand' => $item->on_hand,
];
}
// https://www.php.net/array_values
$item_list['grid'] = array_values($item_list['grid']);
Update: if you want size_grid to be numeric as well, you can do the following:
// your existing code
foreach($items as $item) {
...
// this line is updated, removal of "$item->size_no"
$item_list['grid'][$item->color]['size_grid'][] = [
'size_no' => $item->size_no,
'size_description' => $item->size_desc,
'on_hand' => $item->on_hand,
];
}
// https://www.php.net/array_values
$item_list['grid'] = array_values($item_list['grid']);
OR
...
// https://www.php.net/array_values
$item_list['grid'] = array_values($item_list['grid']);
$item_list['grid'] = array_map(
function ($item) {
$item['size_grid'] = array_values($item['size_grid']);
return $item;
},
$item_list['grid']
);
