I got this:
$arr = json_decode($arr, TRUE);
while($row){
// $arr[] = ['id' => '8', 'name' => 'mickey'];
$test = $row->TCI_LIBELLE;
$arr[] = ['id' => $row->TCI_ID, 'name' => $row->TCI_LIBELLE];
$i +=1;
$row = $reqCentreInteret->fetch(PDO::FETCH_OBJ);
$json = json_encode($arr);
If you don't understand I'm trying to put values I get from a Select SQL query into a JSON array.
The problem is that it does't work like I want.
Indeed it works with my id because in my database it's an int value, but it does't work for the name because it is a varchar value
This is what i want to obtain :
[{"id":"8","name":"mickey"},{"id":"8","name":"mickey"}]
And here 'mickey' will be replaced by the value of my php string that will be initialized by my sql query
I already tried to solve my problem using
'name' => '" .$row->TCI_LIBELLE."'
But it does't work
How can I pass string value (or other type) to my JSON array?
I'm using PHP and JSON to send value from MySQL to an Android app.
arr[] = adds a new row to the array, i.e. a new top-level element.
You probably want to add your data to the existing element
Let's say your arr initially is something like
[ 'property1' => 'value1',
'property2' => 'value2'
...]
when you're doing
arr[] = ['id'=> 8,'name' => 'mickey']
your array will now contain 2 top level elements and look like
[[ 'property1' => 'value1',
'property2' => 'value2'
...
],
[ 'id' => 8,
'name' => 'mickey'
]
]
you may want to do this instead
arr['id'] = $row->TCI_ID;
arr['name'] = $row->TCI_LIBELLE;
then your arr will look like this:
[ 'property1' => 'value1',
'property2' => 'value2'
'id' => 8
'name' => 'mickey'
...
]
Finally this is what is had to do
$stmt = $db->query("SELECT TCI_ID AS id, TCI_LIBELLE AS nom FROM
OSO_DEV.T_CENTRE_INTERET");
echo json_encode($stmt->fetchAll(PDO:: FETCH_ASSOC),JSON_UNESCAPED_UNICODE);
How Can I Create a main array that includes multiple child array And be in the form of Jason and I want to add the child Array to main array in the Loop
MainArray=[
array1=[{fname:asdada,lastname:sdsadasda}];
array2=[{fname:asdada,lastname:sdsadasda}];
array3=[{fname:asdada,lastname:sdsadasda}];
];
echo MainArray[1]->fname;
Please see the following pseudo code below:
pseudo code
You should really look into a basic php tutorial.
This is how you do it.
$mainArray = [
'array1' => ['fname' => 'asdada', 'lastname' => 'sdsadasda'],
'array2' => ['fname' => 'asdada', 'lastname' => 'sdsadasda'],
'array3' => ['fname' => 'asdada', 'lastname' => 'sdsadasda']
];
echo $mainArray['array1']['fname'];
Or use the long notation if you have an older version of php or want backwards compatibility.
$mainArray = array(
'array1' => array('fname' => 'foo', 'lastname' => 'bar'),
'array2' => array('fname' => 'lorem', 'lastname' => 'ipsum'),
'array3' => array('fname' => 'test', 'lastname' => 'example')
);
echo $mainArray['array1']['fname'];
Explanation:
The php variable sigil is $. This means that in order to access a variable or assign something to a variable, you use $mainArray. See more on variables in the documentation.
The php array can be used in two different notations. Either array(...) or, from php 5.4 upwards, [...]. Other than the opening and closing parts, they are identical. You don't use : or = to assign individual values inside an array declaration. For this you use the => operator. Each element in an array is separated by a comma (,).
E.g.
$mainArray = array(
'A' => 1,
'B' => 2
];
Arrays in Php can be either associative or numerical. What you probably want is that your outer array is numerical, meaning you can access it using $mainArray[1], and your inner array is associative. For numerical arrays, you don't specify a key yourself, so there is no need for the =>.
$mainArray = array(
array(),
array(),
array()
);
And with associative sub arrays this becomes:
$mainArray = array(
array('firstname' => 'foo', 'lastname' => 'bar'),
array('firstname' => 'test', 'lastname' => 'example'),
array('firstname' => 'lorem', 'lastname' => 'ipsum')
);
In order to access the firstname key of the first child array in this multilevel array structure, you do:
$mainArray[0]['firstname']
E.g. (if you want to echo it to the standard output)
echo $mainArray[0]['firstname'];
Please note that numerical arrays in php start counting on 0, as in most other programming languages. And please note that the key in the associative array is a string, and as such must be surrounded with either ' or ".
I can recommend you search for a php beginner's tutorial and try to write and execute the examples yourself, to get a better grasp of php. If you need somewhere to run your php examples, I can recommend you try an online php environment such as PHPFiddle.
Update on adding values:
You can add more key=>value pairs to an associative array or add more values to a numerical array afterwards in much the same way as you would access or assign to it.
First, let's add a value to a numerical array. You do this by adding [] to the end of your variable when assigning. This means that what you assign will be added as a new numerical value to the end of your array.
$numericalArray = array(
7,
8,
6,
12,
'B'
);
$numericalArray[] = 'C';
// Results in the array: array(7, 8, 6, 12, 'B', 'C')
And in order to add a new key => value pair to an associative array, you just add it using the new key, e.g.
$assoc = array(
'firstname' => 'Testy',
'lastname' => 'McTestface'
);
$assoc['middlename'] => 'Tester';
So to add a new fname-lastname pair to the mainArray, you would do:
$mainArray = array(
array('fname' => 'foo', 'lastname' => 'bar'),
array('fname' => 'test', 'lastname' => 'example'),
array('fname' => 'lorem', 'lastname' => 'ipsum')
);
$mainArray[] = array('fname' => 'new name', 'lastname' => 'new last name');
If you want to do this in a loop, you will use the for, foreach, while or do while structures.
E.g.
$mainArray = array(
array('fname' => 'foo', 'lastname' => 'bar'),
array('fname' => 'test', 'lastname' => 'example'),
array('fname' => 'lorem', 'lastname' => 'ipsum')
);
for ($i = 0; $i < 3; ++$i) {
$mainArray[] = array('fname' => 'new name ' . $i, 'lastname' => 'new last name ' . $i);
}
echo json_encode($mainArray, JSON_PRETTY_PRINT|JSON_UNESPACED_UNICODE|JSON_UNESCAPED_SLASHES), PHP_EOL;
// [
// {'fname': 'foo', 'lastname': 'bar'},
// {'fname': 'test', 'lastname': 'example'},
// {'fname': 'lorem', 'lastname': 'ipsum'},
// {'fname': 'new name 0', 'lastname': 'new last name 0'},
// {'fname': 'new name 1', 'lastname': 'new last name 1'},
// {'fname': 'new name 2', 'lastname': 'new last name 2'},
// ]
I have multi-dimensional array like below
$records = array(
array(
'id' => 11,
'first_name' => 'John',
'last_name' => 'Doe',
'email' => 'john#gmail.com'
),
array(
'id' => 12,
'first_name' => 'Sally',
'last_name' => 'Smith',
'email' => 'sally#gmail.com'
),
array(
'id' => 13,
'first_name' => 'Jane',
'last_name' => 'Jones',
'email' => 'jane#gmail.com'
)
);
Now,I want the output as array in form of id as key and email as its value.
Array
(
[11] => john#gmail.com
[12] => sally#gmail.com
[13] => jane#gmail.com
)
I want short code for it, Not want any lengthy code.
I have tried it with foreach
$collect_data = array();
foreach($records as $key=>$data){
$collect_data[$data['id']] = $data['email']
}
Any one know short code for above to achieve my requirement.
I think, You can try php in-build function to sort out your solution
$emails = array_column($records, 'email', 'id');
print_r($last_names);
You can also refer following link too.
Php In-build Function (array_column)
This should work for you:
Just array_combine() the id column with the email column, which you can grab with array_column().
$collect_data = array_combine(array_column($records, "id"), array_column($records, "email"));
For compatibility sake, as array_column was introduced in PHP 5.5, consider array_reduce:
$output = array_reduce($records, function($memo, $item){
$memo[$item['id'] = $item['email'];
return $memo;
}, []);
I find it more expressive than a foreach, but that's matter of personal taste.
Here is the query string.
$query = "SELECT t.id, t.assignee, t.owner,
d.code, d.status, d.target_completion_date,
d.target_extension_date, d.submission_date, d.approval_date,
d.revision_start_date, d.revision_completion_date, d.message,
ty.name, f.orig_name, f.new_name,
b.payment_date, b.discount, b.total_cost, b.amount_payed, b.edit_level,
b.billing_type, b.pages, b.words
FROM tasks t
INNER JOIN details d ON t.detail_id = d.id
INNER JOIN billing b ON t.billing_id = b.id
INNER JOIN TYPE ty ON d.document_type_id = ty.id
INNER JOIN files f ON t.file_id = f.id
WHERE t.assignee = 'argie1234'";
And this is the array i would like the query result to turn into.
$user = array('allTask'=>array(array('taskid' => 1,
'assignee'=>'argie1234',
'owner'=>'austral1000',
'details' => array( 'code' => 'E',

How can i create the above array? I sure know how to define multi dimensional array, regretfully though i am having difficulty creating this complex array dynamically. As a beginner i don't even know where to begin.
Here is an example that might help you out. Try starting with simple multi dimensional arrays, once you get a hold of it, you can move onto building complex ones. You will then find that the array you want to build is not really difficult than you initially thought it to be.
$mycomplexarray = array('key1' => array('val1', 'val2'),
'key2' => array('val3', 'val4' => array('val5', 'val6')
)
);
You could create the array just as you have here. I'm not gonna write the whole thing out, but something like this...
$result = $mysqli->query($query); // however you query the db is up to you.
$row = $result->fetch_assoc(); //same as query use your prefered method to fetch
$user = array('allTask'=>array(array('taskid' => $row['id'],
'assignee'=>$row['assignee'],
'owner'=>$row['owner'],
'details' => array( 'code' => $row['code'],
'status'=>$row['status'],
...etc, Hope this makes sense for you.
Set up a structure array first that defines which columns will be stored in a sub array like
$struc=array('Id'->0, 'assignee'->0, 'owner'->0,
'code'->'detail', 'status'->'detail', 'target_completion_date'->'detail',
'target_extension_date'->'detail', 'submission_date'->'detail', 'approval_date'->'detail',
'revision_start_date'->'detail', 'revision_completion_date'->'detail', 'message'->'detail',
'name'->'file', 'orig_name'->'file', 'new_name'->'file',
'payment_date'->'billing', 'discount'->'billing', 'total_cost'->'billing', 'amount_payed'->'billing', 'edit_level'->'billing', 'billing_type'->'billing', 'words');
In your while ($a=mysqli_fetch_assoc($res)) loop you can now use this structure to decide whether you want to store an element directly in your target array or whether you want to place it in the subarray named in this structure array. Like
$res=mysqli_query($con,$sql);
$arr=array();
while($a=mysqli_fetch_assoc($res)) {
// within result loop: $a is result from mysqli_fetch_assoc()
$ta=array(); // temp array ...
foreach ($a as $k => $v){
if ($struc[$k]) $ta[struc[$k]][$k]=$v;
else $ta[$k]=$v;
}
$arr[]=$ta; // add to target array
}
This is the complete code, no more is needed. It was typed up on my iPod, so it is NOT tested yet.
The generated array should be equivalent to your $user['allTask'] array.
i am sending an ordered json_encode list of some MySQL tables, from php, but when i retrieve it with jquery it is not in order any more? everything works fine and in order on the php side. it's the client side that i'm having trouble with. i think the problem is that i'm sending a multidimensional array from php as json. what would be the most efficient solution? also why has the order changed when retrieved by jQuery.
PHP CODE:
$user_data = array();
while($row = mysql_fetch_array($retval, MYSQL_ASSOC){
$user_id = $row['user_id'];
if(!isset($user_data[$user_id]){
$user_data[$user_id] = array(
'first_name' => $row['first_name'],
'last_name' => $row['last_name'],
'dept' => $row['dept'],
'quals' => array()
);
}
$quals = array(
'qual_cat' => $row['qual_cat'],
'qual' => $row['qual'],
'count' => $row['count']
)
$user_data[$user_id]['quals'][] = $quals;
}
echo json_encode($user_data);
jQuery:
$.post('page.php', function(post){
$.each(post, function(i,data){
alert(data.first_name+' '+data.last_name+' - '+data.dept);
});
});
PHP VAR_DUMP:
array
10 =>
array
'first_name' => string 'David' (length=5)
'last_name' => string 'Dan' (length=3)
'dept' => string 'web' (length=3)
'count' => string '5' (length=1)
'quals' =>
array
0 =>
array
...
1 =>
array
...
2 =>
array
...
3 =>
array
...
4 =>
array
...
In php, array is by default associative, so that's why you have this behavior as associative array order is not guaranteed (as per explanation in the link given by benedict_w).
To overcome this, you could try the following:
echo json_encode(array_values($user_data));
This will effectively turn your json from
["10":{prop1:val1, prop2:val2}, "25":{prop1:val1, prop2:val2}]
into
[{prop1:val1, prop2:val2}, {prop1:val1, prop2:val2}]
If you need to keep track of the id, put it inside your user_data in your php:
if(!isset($user_data[$user_id]){
$user_data[$user_id] = array(
'id' => $user_id,
'first_name' => $row['first_name'],
'last_name' => $row['last_name'],
'dept' => $row['dept'],
'quals' => array()
);
}
