I'm storing images links into the database separating them with ,, but I want to transform this string into an array, but I'm not sure how to do it.
So my array looks like this:
$array = array(
"name" => "Daniel",
"urls" => "http:/localhost/img/first.png,http://localhost/img/second.png"
);
So I'd like to have it in the following form:
$array2 = array(
"name" => "Daniel",
"urls" => array("http:/localhost/img/first.png",
"http://localhost/img/second.png" )
);
I haven't been PHP'ing for a while, but for that simple use-case I would use explode.
$array['urls'] = explode(',', $array['urls']);
Uncertain if I interpreted your question correct though?
You can use array_walk_recursive like in the following example.
function url(&$v,$k)
{
if($k=='urls') {
$v = explode(",",$v);
}
}
$array = array(
"name" => "Daniel",
"urls" => "http:/localhost/img/first.png,http://localhost/img/second.png"
);
array_walk_recursive($array,"url");
You can check the output on PHP Sandbox

I have a COLLECTION collflokks in MongoDB, sample Document is :-
{
"_id" : "b_8AUL",
"f_name" : "Pizza. Hut",
"f_lat" : "22.7523513",
"f_lng" : "75.9225847",
"c_uid" : "33",
"f_type" : NumberLong(3),
"members" : [
"42",
"43"
]
}
Within the "members" array , I want to add Arrays like {id:42,name:Mark} , {id:43,name:Hughes}
Currently i'm adding just ids(eg.42,43). I'm only concerned about the new data as it will have new ids .Please suggest.
Earlier I was using this code to push into the members Array:
$flokkCollection = 'collFlokks';
$flokkCollection->update(
array("_id" => $f_handle),
array('$push' => array("members" => $u_id))
);
Well if what you are asking here is "replacing your existing data" then you need to "loop" the results from the collection and "replace" the array content that exists with your new format.
There are likely smarter ways to approach this, but you are not really giving us all the required information in your question, so I can only answer in the basic terms.
Presuming you have:
$required = array(
array(array("id" => "42"), array("name" => "Mark")),
array(array("id" => "43"), array("name" => "Hughes"))
);
As input, then you do something like this:
function myMapper($v) {
return $v["id"];
}
$mapped = array_map("myMapper",$required);
foreach( $mapped as $value) {
$filtered = array_values(
array_filter($required,function($k) {
return $k["id"] == $value;
})
)[0];
collection.update(array(
array("members" => $value),
array('$set' => array(
"members.$" => $filtered
))
));
}
Which should use the positional $ operator to find the matched "position" of the array element by the value used in the "query" portion of the update statement, then in the "update" portion of that statement $set that current array index to the new value at the "filtered" content index from the original input array.
Outside of PHP. We call these inner elements "objects" and not "arrays" which is a PHP notation trait. Key/value things are "objects" and "lists" are "arrays".
I'm trying to make my json output in the following format below, but I do not know how to code it to make it display in just format... I just have the values, any kind of help I can get on this is greatly appreciated!
{
"firstcolumn":"56036",
"loc":"Deli",
"lastA":"Activity",
"mTime":"2011-02-01 11:59:26.243",
"nTime":"2011-02-01 10:57:02.0",
"Time":"2011-02-01 10:57:02.0",
"Age":"9867 Hour(s)",
"ction":" ",
"nTime":null
},
{
"firstcolumn":"56036",
"loc":"Deli",
"lastA":"Activity",
"mTime":"2011-02-01 11:59:26.243",
"nTime":"2011-02-01 10:57:02.0",
"Time":"2011-02-01 10:57:02.0",
"Age":"9867 Hour(s)",
"ction":" ",
"nTime":null
}
You can use a PHP associative array to set the key => value's of your array to be converted to json. As you would expect the key of the php associative array becomes the key of the JSON object, and the same with the values.
$array = array(
'firstcolumn' => '56036',
"loc" => "Deli",
"lastA" => "Activity",
"mTime" => "2011-02-01 11:59:26.243",
"nTime" => "2011-02-01 10:57:02.0",
"Time" => "2011-02-01 10:57:02.0",
"Age" => "9867 Hour(s)",
"ction" => "",
"nTime" => NULL
);
You can do both arrays like this (using previous array to show concept but can replace with that same array())
$array2 = $array1;
$array2['firstcolumn'] = "56037";
$botharrays = array($array, $array2);
What we just did is put both sub arrays into one containing array so that when you encode the json it has each object separately.
array( array1, array2 )
Then use json_encode() to encode the array into the json format you requested
$JSON= json_encode($array);
or
$json = json_encode($botharrays);
I think you are looking for this:
$json = json_encode($myArray);
print_r($json);
i want to store associative array into a variable a as a string, and then convert the variable into array.
$var='"electirc_bill"=>array(
"type" => "number",
"required"=>"yes"
),
"electirc_bill_per"=>array(
"type" => "number",
"required"=>"yes"
),
"gass_bill"=>array(
"type" => "number",
"required"=>"yes"
)
)';
var_dump($var);
Use serialize and unserialize.
Convert the array to string:
$string = serialize($array);
Convert it back to an array:
$array = unserialize($string);
Edit: Based on your comment you seem to already have the array stored as a string and want to be able to convert it to an array. For that I would use eval but be cautious when using it with any user input as it could lead to security vulnerabilities within your code.
I've made a small example using your code here: http://codepad.org/rPNXPBlW
$var = '$array_var = array("One" => array("1.1", "1.2"), "Two" => array("2.1", "2.2"));';
eval($var);
echo $array_var['One'][0]; // Shows 1.1
Use like below,
$json_str = json_encode($var);
first then use json_decode($json_str); where required
// save
file_put_contents('file.json', json_encode($array));
// load
$array = json_decode(file_get_contents('file.json'), true);
You can use serialize and unserialize like this:
<?
$var=array("electirc_bill"=>array(
"type" => "number",
"required"=>"yes"
),
"electirc_bill_per"=>array(
"type" => "number",
"required"=>"yes"
),
"gass_bill"=>array(
"type" => "number",
"required"=>"yes"
)
);
var_dump($var);
$string = serialize($var);
var_dump($string);
$array = unserialize($string);
var_dump($array );
?>
WORKING CODE
Here i give suggestion to use this array will meet your requirement
$name=array('parent1'=>array('childone'=>'harish','childtwo'=>'vignesh'),'parent2'=>array('childone'=>'our children'));
echo "<pre>";
print_r($name);
foreach($name as $parents)
{
foreach($parents as $child)
{
echo "<pre>"; print_r($child);
}
}
I am using PHP and trying to create an array that looks something like this:
{
"aps" : {
"alert" : "Hey"
},
"custom_control" : {
"type" : "topic_comment",
"object":{
"topic_id":"123",
"topic_section":"test"
"plan_id":"456"
}
}
}
So far I have something like
$message = array('aps'=>array('alert'=>$some_variable));
but I am getting confused how I can put the values for "custom_control" into this array after that. Could anyone please advise how to do that from my existing php?
Thanks!
Is this what you mean?
<?php
$some_variable = "Hey";
$myArray = array(
"aps" => array(
"alert" => $some_variable
),
"custom_control" => array(
"type" => "topic_comment",
"object" => array(
"topic_id" => "123",
"topic_section" => "test",
"plan_id" => "456"
)
)
);
?>
Here is an easy way to discover what you need to do.
Create your JSON object.
Use it as input to the json_decode function.
Use the output of this as the input to var_export()
So supposing you assigned your JSON to $json_object, then use:
var_export(json_decode($json_object, true));
If you are more comfortable building the object in JSON you can use the JSON parser included in php. Also, JSON defines Javascript objects, not arrays (although you can define arrays in JSON with something like {myArray : [1,2,3]}
Try this if you want though:
http://php.net/manual/en/function.json-decode.php
If you've already created your initial message array (per your question), you would then do something like this.
$message["custom_control"] = array(
"type" => "topic_comment",
"object" => array(
"topic_id" => "123",
"topic_section" => "test",
"plan_id" => "456"
)
)
You can create whatever nodes you needs inside of $message this way.
What you are trying to create is not an array, but rather an object.
Try to not build it as an array but an object.
$obj = new stdClass();
$obj->aps = new stdClass();
$obj->aps->alert = 'Hey';
$obj->custom_control = new stdClass();
$obj->custom_control->type = 'topic_comment';
$obj->custom_control->object = new stdClass();
$obj->custom_control->object->topic_id = '123';
$obj->custom_control->object->topic_section = 'test';
$obj->custom_control->object->plan_id = '456';
$json = json_encode($obj);
$array = array();
$array['aps'] = "alert";
$array['custom_control'] = array();
$array['custom_control']['type'] = "topic_comment";
$array['custom_control']['object'] = array('topic_id' => '123',
'topic_section' => 'test',
'plan_id' => '456');
i think you need something like this:
$message =array( "aps" =>array("alert"=>"Hey"),
"custom_control" => array(
"type" => "topic_comment",
"object" => array(
"topic_id"=>"123",
"topic_section"=>"test",
"plan_id"=>"456"
)
)
);
In php I'm willing to check the existence of indexes that match with another values in array.
$indexes = array("index", "id", "view");
$fields = array(
"index" => 5,
"id" => 7,
"form" => 10,
"date" => 10,
);
MY ideal result is, in this case, to get "form" and "date". Any idea?
Try
$fields_keys = array_keys($fields);
$fields_unique = array_diff($fields_keys, $indexes);
The result will be an array of all keys in $fields that are not in $indexes.
You can try this.
<?php
$indexes = array("index", "id", "view");
$fields = array(
"index" => 5,
"id" => 7,
"form" => 10,
"date" => 10,
);
$b = array_diff(array_keys($fields), $indexes);
print_r($b);
You can use array_keys function to retrieve keys of a array
Eg:
$array = array(0 => 100, "color" => "red");
print_r(array_keys($array));
Outputs
Array
(
[0] => 0
[1] => color
)
PHP Documentation
Your question is a little unclear but I think this is what you're going for
array_keys(array_diff_key($fields, array_fill_keys($indexes, null)));
#=> Array( 0=>"form", 1=>"date" )
See it work here on tehplayground.com
array_keys(A) returns the keys of array A as a numerically-indexed array.
array_fill_keys(A, value) populates a new array using array A as keys and sets each key to value
array_diff_key(A,B) returns an array of keys from array A that do not exist in array B.
Edit turns on my answer got more complicated as I understood the original question more. There are better answers on this page, but I still think this is an interesting solution.
There is probably a slicker way than this but it will get you started:
foreach(array_keys($fields) as $field) {
if(!in_array($field, $indexes)) {
$missing[] = $field;
}
}
Now you will have an array that holds form and date.
