I get array data with this format:
For example:
array = [
"index-category",
"create-category",
"store-category",
"show-category",
"index-products",
"create-products",
"store-products",
"show-products",
"edit-products",
"index-sales",
"create-sales",
]
I need convert to :
array {
0 => {
"index-category",
"create-category",
"store-category",
"show-category",
},
1 => {
"index-products",
"create-products",
"store-products",
"show-products",
"edit-products",
}
2 => {
"index-sales",
"create-sales",
}
}
How to convert to this array?
Is php a method that automatically converts ?

Answer 1

I think you just mess up with proper array notation here. Array notation no uses curly braces { or }. So If it is a proper array then you can try like this way using array_chunk()
N.B : For array notation we can use two different ways e.g $array = [] or $array=array()
<?php
$array = [
'category.index',
'category.create',
'category.store',
'category.edit',
'product.index',
'product.create',
'product.store',
'product.edit',
'city.index',
'city.create',
'city.store',
'city.edit',
];
print '<pre>';
print_r(array_chunk($array,4));
print '</pre>';
?>
Output:
Array
(
[0] => Array
(
[0] => category.index
[1] => category.create
[2] => category.store
[3] => category.edit
)
[1] => Array
(
[0] => product.index
[1] => product.create
[2] => product.store
[3] => product.edit
)
[2] => Array
(
[0] => city.index
[1] => city.create
[2] => city.store
[3] => city.edit
)
)

EDIT:
AS PER YOUR QUESTION UPDATE
Simply try like this with list()
$new = array();
foreach($array as $val) {
list($item, $number) = explode('.', $val);
$new[$item][] = $val;
}
print '<pre>';
print_r(array_values($new));
print '</pre>';
DEMO: https://eval.in/980176
Output:
Array
(
[0] => Array
(
[0] => category.index
[1] => category.create
[2] => category.store
[3] => category.edit
)
[1] => Array
(
[0] => product.index
[1] => product.create
[2] => product.store
)
[2] => Array
(
[0] => city.index
[1] => city.create
[2] => city.store
[3] => city.edit
)
)
EDITED AGAIN
As you've different initial array on your question now so now code should be like this.
$new = array();
foreach($array as $val) {
list($item, $number) = explode('-', $val);
$new[$number][] = $val;
}
print '<pre>';
print_r(array_values($new));
print '</pre>';

This would be a simple algorithm to convert the input data:
<?php
$input = [
'category.index',
'category.create',
'category.store',
'category.edit',
'product.index',
'product.create',
'product.store',
'city.index',
'city.create',
'city.store',
'city.edit',
];
$category = [];
array_walk($input, function ($entry) use (&$category) {
$tokens = explode('.', $entry);
$category[$tokens[0]][] = $entry;
});
$output = array_values($category);
print_r($output);
The output obviously is:
Array
(
[0] => Array
(
[0] => category.index
[1] => category.create
[2] => category.store
[3] => category.edit
)
[1] => Array
(
[0] => product.index
[1] => product.create
[2] => product.store
)
[2] => Array
(
[0] => city.index
[1] => city.create
[2] => city.store
[3] => city.edit
)
)
Here is the same algorithm with a trivial modification to match the changed input data you now suddenly presented by updating the question and commenting to this answer.
As already mentioned before in the comments all this does not really affect the algorithm, tiny adjustments will again deliver the desired output:
<?php
$input = [
"index-category",
"create-category",
"store-category",
"show-category",
"index-products",
"create-products",
"store-products",
"show-products",
"edit-products",
"index-sales",
"create-sales",
];
$category = [];
array_walk($input, function ($entry) use (&$category) {
$tokens = explode('-', $entry);
$category[$tokens[1]][] = $entry;
});
$output = array_values($category);
print_r($output);
This will, as expected, result in that output:
Array
(
[0] => Array
(
[0] => index-category
[1] => create-category
[2] => store-category
[3] => show-category
)
[1] => Array
(
[0] => index-products
[1] => create-products
[2] => store-products
[3] => show-products
[4] => edit-products
)
[2] => Array
(
[0] => index-sales
[1] => create-sales
)
)
