I have 2 tables i.e user and photo. According to user_id get all the user details and all the photos from the photo table.
I am creating a web-service using slim framework. How is it possible to make a array like above given format?
How to make a array like following format?
array(
[id]=>
[name]=>
[email]=>
[dob]=>
[gallery]=>array(
[0] => 1.png
[1] => 2.png
)
[address]=> xyz
)
If your question is strictly about how to make the nested array, then here is a solution.
// create the nested portion of the array
$images = ['1.png', '2.png'];
// create the rest of the array
$result = [
'id' => 1,
'name' => 'default',
'email' => '123#abc.com',
'dob' => '3/4/89',
'gallery' => $images,
'address' => 'xyz'
];
Note how we set 'gallery' => $images. If you need data from two different tables to be retrieved at the same time and formatted like this, then that would probably be easiest to achieve using a join in your query. If you need help with that just say so.

I am writing a page that pulls images and image data out of a multidimensional array. I need to be able to click a button that calls a function to sort out the images by tags(IE tag_GlassDoor & tag_GlassWall) - basically to show only images that do or do not have that particular element (in this case im using 0 and 1 for yes and no), such as a glass door. I can currently make that array display the data, but I cant figure out how to sort the data by one of the array keys, or even really the syntax to pull a single value out at will.
$arrImages[] =
[
'img_sm'=>'image1.jpg',
'tag_GlassDoor'=>0,
'tag_GlassWall'=>1,
];
$arrImages[] =
[
'img_sm'=>'image2.jpg',
'tag_GlassDoor'=>1,
'tag_GlassWall'=>1,
];
Filtering is the answer, it can be used to filter one dimensional Arrays and multidimensional arrays.
the general implementation would be something like this:
$arr = array(
array(
'image' => "data",
'hasObject' => 1
),
array(
'image' => "data",
'hasObject' => 0
),
);
$finteredArray = array_filter($arr, function ($r) {
return (bool) $r['hasObject'];
});
print_r($finteredArray);
// it outputs:
// Array ( [0] => Array ( [image] => data [hasObject] => 1 ) )
I am currently building a web planning and I want to show some data in the period display.
I have a PHP file where I create my SQL request over ~13 tables and fetch all results (I use PDO::FETCH_ASSOC), then I have to loop over my result to build the array I want.
The problem is I need to build a complicated array with lot of data. Here is the kind of result I want to achieve :
$result = array(
$place_1 => array(
'data_place' => array(
'id' => ...,
'name' => ...,
// etc.
),
'data_target' => array(
$target_type_1 => array(
$name_1 => ...,
$name_2 => ...,
// etc.
),
$target_type_2 => array ( ... ),
// etc.
),
'data_isOpen' => array(
$day_1 => array(
$hour_begin => ...,
$hour_end => ...
),
$day_2 => array ( ... ),
// etc.
),
'data_box' => array(
// same kind of stuff with more dimension
)
),
...
$place_n = array(
// same
)
);
When I execute my request, I get something like 3000 array with all the data I need, but I only have 29 places in database so there is a lot of repetition...
$result = array(
0 => array(
"id" => ...,
"name" => ...,
// the list of all fields I need in my big array
),
...
n => array(
// same
)
);
I almost manage to achieve the result I want with some "foreach" and headaches but here is my question :
Is it possible to build a SQL request and fetch the result as I want? I mean, can I group all the result by "id_place" for example but wihtout lost information? And if it's possible, can we do it multiple time?
The idea is to get a result with one array for every place (so 29 and not 3000), then for every "place array", group for example the "hour_begin" and "hour_end" by "opening_day", etc...
Sorry if it's a duplicate, I didn't saw any positive anwser to my question so I try again !
Let's say I have an array
$array = array(
'username' => "username",
'location' => "location",
'other' => "other");
This array can hold data for many users, so there could be different values for each 'username', 'location', and 'other' fields. How can I use in_array() or another function to determine if a specific username exists in the array already? Because what if a user has a username like "nyc" and a location of "nyc" and I do
in_array("nyc", $array);
How exactly should something like this be approached?
Thank you.
To achieve something that I think is what you want, you can make an array of associative arrays that have the same keys.
<?php
// This syntax will work only on PHP 5.4
$a=[["name"=>"john","age"=>25],["name"=>"philip","age"=>110]];
print_r(array_filter($a, function($item) {return $item["name"] === "john"; }));
?>
Outputs:
Array
(
[0] => Array
(
[name] => john
[age] => 25
)
)
If you just wanted to know if a person named John was in the list, you can just use sizeof/count on the returned array.
This will allow you to have any number of duplicates, and you don't need to specify any keys. Check out the functions: array_filter, array_reduce, array_map. With all of these, you can process your list using closures like in my example above.
Instead of using associative arrays in your array, you could have objects too. Objects are more heavyweight, and need initialization and stuff, so it is grotesque for using them for tiny static (hardcoded) lists. But they may come handy when your data structures grow and you want to make sure every list item has a certain property (the constructor of the class could ensure that everything is initialized). But the good thing is that filter, reduce and map would still work. The "$item" would then be your object.
$users = array( 'user_id' => array('username' => "username",
'location' => "location",
'other' => "other");
user_id is their NUMBER user_id
So you then call $users['####']['username'];
IE:
$users = array( '1' => array('username' => 'Jim',
'location' => 'Florida',
'other' => "other"),
'2' => array('username' => 'Jane',
'location' => 'Maryland',
'other' => "Grapes"));
Then use array_keys() to search for their user_id
I am trying to build a travel itinerary system. The user selects the dates of travel, and then may add items to each day.
I have an array of dates, stored in a session in the format:
array(
(int) 0 => '2012-08-25',
(int) 1 => '2012-08-26',
(int) 2 => '2012-08-27'
)
They will then choose attractions, which I wish to store in an array in the format:
array(
(int) 0 => array(
'Attraction' => array(
'attraction_id' =>'1',
'name' => 'Place One',
)
),
(int) 1 => array(
'Attraction' => array(
'attraction_id' => '2',
'name' => 'Place Two',
)
),
I'd like to be able to output:
2012-08-25
Place One
Place Two
2012-08-26
nothing here yet!
2012-08-27
nothing here yet!
So, each item of the first array contains an array of items, if that makes sense. I am struggling with the logic of associating the keys of the days array with the items array.
I looked at array_merge but that doesn't seem to do what I need.
Is there an easy way to achieve this?
This code does exactly what you ask. Unfortunately, I fear your question doesn't reflect your aim given the example. Using keys to link data will led to 1-1 relationship, where as you seem to need a 1-n. You should have a foreign key field in the attraction array, like date_id.
$array= array();
foreach($dates as $date_key=>$date){
$array[$date]=array();
foreach($attractions as $attraction_key=>$attraction){
if($date_key==$attraction_key){
$array[$date][]=$attraction['Attraction']['name'];
}
}
}
I'm probably missing something simple here but I can't seem to find a way to build a query that will allow me to update a match in a group of nested values.
I have a document like this for a blog app I've been working on (currently uses MySQL):
array (
'_id' => new MongoId("4bc8dcee8ba936a8101a0000"),
'created' => '20100418-201312 +0000',
'post-title' => 'Some Post Title',
'post-body' => 'Blah Blah Blah Blah.',
'post-blog-name' => 'default',
'post-comments' =>
array (
0 =>
array (
'comment-title' => 'Test1',
'comment-body' => 'asdf1',
'created' => '20100418-214512 +0000',
'owner' => 'User1',
),
1 =>
array (
'comment-title' => 'Test2',
'comment-body' => 'asdf2',
'created' => '20100418-214512 +0000',
'owner' => 'User2',
),
),
'owner' => 'zach',
'updated' => '20100418-201312 +0000',
)
I'd like to be able to build a query that can search 'comment-title' for a match and then allow me to update/change/delete data as needed.
Obviously I can perform an update using a query which includes the key value. Something like this works:
$collection->update(
array("post-comments.0.comment-title" => $_POST['comment-title']),
array('$set' => array('entries.0' => array('comment-title' => $_POST['comment-title'], 'comment-body' => $_POST['comment-body'], 'owner' => $_SESSION['username'], 'updated' => gmdate('Ymd\-His O')))));
But I expect I'm missing something that would allow me to leave out the key and still be able to match one of the nested arrays based on a value (in this example the 'comment-title').
Anyway, sorry, this probably isn't the best example and I probably will end up using the keys in comments to identify them (comment #) but since nesting and creating rather complex objects seem to be a few of Mongodbs strong points I'm just hoping someone can point out what it is I might be missing.
A query to remove or update all comments by a specific user (say a user the blog author just black-listed) might be a better example. I'm not sure how I'd do this short of pulling out the entire document and then iterating through the nested arrays using PHP.
try ... notice I removed the "key"
$collection->update(array("post-comments.comment-title" ...
Cheers!
