I was unable to output this:
[{"title":"London","foo":"bar"},{"title":"Istanbul","foo":"bar"}]
I cannot make comma here: },{
I can output this [{"title":"London","foo":"bar"}] but not the first example.
This will produce the desired output:
$data = array(
array("title" => "London",
"foo" => "bar"
),
array("title" => "Istanbul",
"foo" => "bar"
)
);
echo json_encode($data);
Make sure you create your arrays correctly. For more information have a look at the documentation for json_decode.

My question is a bit different to most like this, I basically want to do the opposite to this question from Haluk.
So I have a JSON string:
{
"main":
{
"title": "QuickPub",
"defaultRole": "BU"
},
"roles":
{
"TU":
{
"name": "testUser",
"code": "TU"
}
}
}
and I want to be able to generate a string containing a php array definition from it:
<?php
return [
"main" =>
[
"title" => "QuickPub",
"defaultRole" => "BU"
],
"roles" =>
[
"TU" =>
[
"name" => "testUser",
"code" => "TU"
]
]
];
?>
EDIT:
I have tried json_decode() but this produces a variable, I need a string that I can put in a php file that will reproduce this without using php_decode.
I think this will solve your problem. First of all convert your json string to an array using json_decode($string,1); then convert that array to string representation using print_r($array,1); this will return your result as array string representation.
For example:
$json='{}' // its a demo
$array= json_decode($json,1); // an array
$result = print_r($array,1);
echo $result;
This is an adaptation of Being Sunny's answer, but using the var_export() function rather than print_r.
As described here by phihad
var_export prints valid php code. Useful if you calculated some values and want the results as a constant in another script
the script:
$json = '{"main":{"title": "QuickPub","defaultRole": "BU"},"roles":{"TU":{"name": "testUser","code": "TU"}}}';
$array = json_decode($json, 1);
$result = var_export($array, 1);
echo $result;
produces:
array(
'main' => array(
'title' => 'QuickPub',
'defaultRole' => 'BU',
),
'roles' => array(
'TU' => array(
'name' => 'testUser',
'code' => 'TU',
),
),
)
This can be achieved using this code:
$output = 'return ' . rtrim(preg_replace(['/{/', '/}/', '/:/'], ['[', ']', ' =>'], $json)) . ';';
this replaces { with [, } with ], and : with =>, trims any whitespace from the end, appends a ; and prepends a return statement.
this produces the output requested in the question bar the open and closing php tags.
I am able to create array values using
$array = array("key" => "value" ... );
Now I want to add them dynamically after assigning the value to $array
<?php
$array = array(
"foo" => "bar",
42 => 24,
"multi" => array(
"dimensional" => array(
"array" => "foo"
)
)
);
var_dump($array["foo"]);
var_dump($array[42]);
var_dump($array["multi"]["dimensional"]["array"]);
?>
This helps you. Refer the php documentation of arrays.
you can access your array by using [] so
$array["new_key"] = "new value";
I am creating a JSON structure to be passed back to Ajax. I would like to insert 'para' => "Hello" into "content" like this:
{
"sections": {
"content": [{
"para": "Hello"
}]
}
}
I tried using this code:
$array = array('sections' => array());
array_push($array["sections"], array("content" => array())); // content must be initialized as empty
array_push($array["sections"][0], array("para" => "Hello"));
But I received this instead:
{
"sections": [{
"content": [],
"0": {
"para": "Hello"
}
}]
}
If I try array_push($array["sections"]["content"], array("para" => "Hello")), I get an error instead. How do I insert an array into "content"? What am I doing wrong?
If I understood your intentions correctly, here's the array structure you're aiming for:
array("sections" => array(
"content" => array("para" => "Hello"),
));
However, in Javascript [] represents an array and {} represents an object. If you're trying to create an object with a property of "0", that's not possible in PHP. Variable names have to start with a letter or underscore.
Here's an array of content objects:
$content = new stdClass();
$content->para = 'hello';
array("sections" => array(
"content" => array($content),
));
To add arrays of contents:
array("sections" => array(
"content" => array(
array("para" => "Hello"),
array("para" => "Hello"),
array("para" => "Hello"),
),
));
You can also construct your own contents array first if you're iterating over an index and then json_encode it. Basic example:
$content = array();
for (i=0; i <3; i++) {
$content[] = array('para' => 'hello');
}
json_encode(array("sections" => array(
"content" => array($content),
)));
To convert that to JSON, put your array inside a json_encode() call.
$array['sections'] = array("content" => array(array("para" => "Hello")));
echo json_encode($array);
will give the result in desired format
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'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");
