I am getting some extra slashes while making json array using PHP. My code is below.
<?php
$output=array(array("first_name"=>"robin","last_name"=>"sahoo","reg_no"=>12,"paper_code"=>"BA001","subject"=>"Mathematics"),array("first_name"=>"robin","last_name"=>"sahoo","reg_no"=>12,"paper_code"=>"BA002","subject"=>"History"),array("first_name"=>"Rama","last_name"=>"Nayidu","reg_no"=>13,"paper_code"=>"BA001","subject"=>"Geology"),array("first_name"=>"robin","last_name"=>"sahoo","reg_no"=>12,"paper_code"=>"BA003","subject"=>"Science"));
$result = []; // Initialize result array
foreach ($output as $key => $value) {
$name = $value['first_name'] . ' ' . $value['last_name'];
// check if same name already has entry, create one if not
if (!array_key_exists($name, $result)) {
$result[$name] = array(
'reg_no' => $value['reg_no'],
'name' => $name,
'paper1' => '',
'paper2' => '',
'paper3' => '',
'paper4' => ''
);
}
// count array elements with value, then set paper number and value
$paper = 'paper' . (count(array_filter($result[$name])) - 1);
$result[$name][$paper] = $value['paper_code'].'/'.$value['subject'];
}
$result = array_values($result); // reindex result array
echo json_encode($result);exit;
?>
Here the json output is given below.
[{"reg_no":12,"name":"robin sahoo","paper1":"BA001\/Mathematics","paper2":"BA002\/History","paper3":"BA003\/Science","paper4":""},{"reg_no":13,"name":"Rama Nayidu","paper1":"BA001\/Geology","paper2":"","paper3":"","paper4":""}]
Here my problem is I am adding $value['paper_code'].'/'.$value['subject']; and in output I am getting "BA001\/Mathematics". Here One extra slash(\) is added which I need to remove.
You can add JSON_UNESCAPED_SLASHES as the second parameter. LIke:
$result = array_values($result); // reindex result array
echo json_encode($result,JSON_UNESCAPED_SLASHES);exit;
This will result to:
[{"reg_no":12,"name":"robin sahoo","paper1":"BA001/Mathematics","paper2":"BA002/History","paper3":"BA003/Science","paper4":""},{"reg_no":13,"name":"Rama Nayidu","paper1":"BA001/Geology","paper2":"","paper3":"","paper4":""}]

I have a variable $a='san-serif' and an array Font_list[] now I want only the arrays whose category is 'san-serif' will be filtered. I tried a lot of codes nothing seems working here is my code:-
public function filterFont() {
$a = $_POST['key'];
$url = "https://www.googleapis.com/webfonts/v1/webfonts?key=''";
$result = json_decode(file_get_contents( $url ));
$font_list = "";
foreach ( $result->items as $font )
{
$font_list[] = [
'font_name' => $font->family,
'category' => $font->category,
'variants' => implode(', ', $font->variants),
// subsets
// version
// files
];
}
$filter = filter($font_list);
print_r(array_filter($font_list, $filter));
}
Please help me :-(
What i understood according to that you want something like below:-
<?php
$a='san-serif'; // category you want to search
$font_list=Array('0'=>Array('font_name' => "sans-sherif",'category' => "san-serif"),'1'=>Array('font_name' => "times-new-roman",'category' => "san-serif"),'2'=>Array('font_name' => "sans-sherif",'category' => "roman"));
// your original array seems something like above i mentioned
echo "<pre/>";print_r($font_list); // print original array
$filtered_data = array(); // create new array
foreach($font_list as $key=>$value){ // iterate through original array
if($value['category'] == $a){ // if array category name is equal to serach category name
$filtered_data[$key] = $value; // assign that array to newly created array
}
}
echo "<pre/>";print_r($filtered_data); // print out new array
Output:- https://eval.in/597605

php json_encode not working on arrays partially
(2 answers)
Closed 7 years ago.
I am trying to properly create and encode and array using json_encode php function. The array i am trying to encode is $myarray . From my code if do
$myarray = array(array('name' =>$value['display_name']->scalarval(),'id' => $value['id']->scalarval())) ;
then
echo json_encode($myarray) ; // this works but only one item is pushed to my array
if i do
$myarray[] = array(array('name' =>$value['display_name']->scalarval(),'id' => $value['id']->scalarval //pushing all elements to array
result is nothing.
what i am missing ?
see full code below on what i have so far done.
<?php
error_reporting(E_ALL);

//
//create an array
$ids = array();
//create a for loop and loop through the ids from search
for($i = 0; $i <= count($customer); $i++ )
{
// assign array values
$ids [] = $customer[$i] ;
}
// read partner with $ids
$customer_details = $connection_model->read('res.partner', $ids);
//loop through the scalavar value

$value = $values->scalarval();
//Push values to my array
$myarray [] = array(array('name' =>$value['display_name']->scalarval(),'id' => $value['id']->scalarval())) ;
//
}
//Then try to encode $myrray but this fails
$jsonstring = json_encode($myarray);

}

please help. thank you.
The right way to create the array would be like this:
$myarray = array(
array(
'name' => 'bla',
'id' => 1
), array(
'name' => 'blas',
'id' => 2
)
);
This part of your code is perfectly fine.
$data = array() ; //create new empty array
//loop through the array
foreach($myarray as $keys => $h)
{
$data [] = $h;
}
//encode
echo json_encode($data) ; //this fails silently
If you run the code, it works perfectly fine:
[{"name":"bla","id":1},{"name":"blas","id":2}]
Your foreach() loop creates a new array $data with the same entries (also arrays) as the $myarray contains. So, you could directly encode $myarray like this:
<?php
$myarray = array(
array('name' =>' Agrolait', 'id' => 6 ),
array('name' => 'Agrolait, Michel Fletcher', 'id' => 31 ),
array('name' => 'Agrolait, Thomas Passot', 'id' => 30 )
);
$jsonstring = json_encode($myarray);
if ($jsonstring!==false) {
echo $jsonstring;
} else {
echo 'Could not properly encode $myarray';
}
?>
Which produces this JSON string:
[{"name":" Agrolait","id":6},{"name":"Agrolait, Michel Fletcher","id":31},{"name":"Agrolait, Thomas Passot","id":30}]
json_encodereturns the value FALSE if something went wrong, and the encoded string else. If you check the result from it you at least know when it fails.
Thanks for your suggestion have solved this. My string data was not properly encoded using utf-8 as suggested by http://nl3.php.net/manual/en/function.json-encode.php. Check my answer below

//create a for loop and loop through the ids from search
for($i = 0; $i <= count($customer); $i++ )
{
// assign array values
$ids [] = $customer[$i] ;
}
// read partner with $ids
$customer_details = $connection_model->read('res.partner', $ids);
//loop through the scalavar value
$myarray = null;
// loop through the value returned
foreach ($customer_details as $keys => $values)
{
$value = $values->scalarval();
$myarray [] = array('name' =>utf8_encode($value['display_name']->scalarval()),'id' => utf8_encode($value['id']->scalarval())) ;
//
//array_push($better, $myarray) ;
}
//echo '<pre>';
//print_r($myarray) ;

echo json_encode($myarray);
exit;

I am getting following response in JSON format and I want it to convert it into PHP variables.
JSON:
{"CreateTransactionResponse":{"CreateTransactionResult":{"TransportKey":"aa900d54-7bfb-47e9-a5de-e423ec34a900"
,"ValidationKey":"fbb28b32-f439-4801-a434-99c70aa388ca","Messages":{}}}}
output should be PHP:
$transkey = aa900d54-7bfb-47e9-a5de-e423ec34a900;
$vkey = fbb28b32-f439-4801-a434-99c70aa388ca
please advice me how to do it.
Just simply use json_decode();
$result= json_decode($jSon);
var_dump($result); // to see the output
json to array(json_decode) and then extract from array.
$arr = json_decode($json, true);
extract($arr);
var_dump($CreateTransactionResponse);
Output:
array (size=1)
'CreateTransactionResult' =>
array (size=3)
'TransportKey' => string 'aa900d54-7bfb-47e9-a5de-e423ec34a900' (length=36)
'ValidationKey' => string 'fbb28b32-f439-4801-a434-99c70aa388ca' (length=36)
'Messages' =>
array (size=0)
empty
More about extract
use $CreateTransactionResult['TransportKey'] to access Transport Key from JSON. Similarly $CreateTransactionResult['ValidationKey'] for Validation Key.
If you want to access your json try to decode it first:
$result = json_decode($yourJSON, true);
foreach($result['CreateTransactionResponse'] as $key => $val){
echo $transkey = 'TransportKey= ' . $val['TransportKey'] . '<br/>;
echo $vkey = 'ValidationKey= ' . $val['ValidationKey'];
}
Or if it is an array of JSON's
$result = json_decode($yourJSON, true);
$data = [];
foreach($result['CreateTransactionResponse'] as $key => $val){
$data[] = [
'TransportKey' => $val['TransportKey'],
'ValidationKey' => $val['ValidationKey']
];
}
print_r($data);
try this code it will work
$JSON='{"CreateTransactionResponse":{"CreateTransactionResult":{"TransportKey":"aa900d54-7bfb-47e9-a5de-e423ec34a900" ,"ValidationKey":"fbb28b32-f439-4801-a434-99c70aa388ca","Messages":{}}}}';
$arr=json_decode($JSON, TRUE);
foreach ($arr as $value) {
foreach ($arr['CreateTransactionResponse'] as $key => $var) {
echo 'TransportKey = '.$var['TransportKey'].'<br>';
echo 'ValidationKey = '.$var['ValidationKey'].'<br>';
foreach ($var['Messages'] as $key => $msg) {
echo 'Messages = '.$msg.'<br>';
}
}
}
In this case,If its a single and TransportKey and a single ValidationKey value (not an array/object is passed) at a time, this is the simplest. Else if object contains objects or inside objects that we want to use or convert to variable, should use a foreach to loop through the object.
//Debuggig
//The string you provided is converted to a json object
//In your case if it is a json object already pass directly it to $j
//below is just for debugging and understanding
//$json='{"CreateTransactionResponse":{"CreateTransactionResult":{"TransportKey":"aa900d54-7bfb-47e9-a5de-e423ec34a900","ValidationKey":"fbb28b32-f439-4801-a434-99c70aa388ca","Messages":{}}}}';
//$j=json_decode($json);
$transkey=$j->CreateTransactionResponse->CreateTransactionResult->TransportKey;
$vkey=$j->CreateTransactionResponse->CreateTransactionResult->ValidationKey;
echo $transkey."</br>";
echo $vkey."<br/>";
/*result as said:
aa900d54-7bfb-47e9-a5de-e423ec34a900
fbb28b32-f439-4801-a434-99c70aa388ca

Here is example how my array should look like:
$library = array(
'book' => array(
array(
'authorFirst' => 'Mark',
'authorLast' => 'Twain',
'title' => 'The Innocents Abroad'
),
array(
'authorFirst' => 'Charles',
'authorLast' => 'Dickens',
'title' => 'Oliver Twist'
)
)
);
When I get results from oracle database:
$row = oci_fetch_array($refcur, OCI_ASSOC+OCI_RETURN_NULLS);
But when I execute my code I only get one row.
For example: <books><book></book><name></name></books>
But I want all rows to be shown in xml.
EDIT:
This is my class for converting array to xml:
public static function toXml($data, $rootNodeName = 'data', &$xml=null)
{
// turn off compatibility mode as simple xml throws a wobbly if you don't.
if (ini_get('zend.ze1_compatibility_mode') == 1)
{
ini_set ('zend.ze1_compatibility_mode', 0);
}
if (is_null($xml))
{
$xml = simplexml_load_string("<".key($data)."/>");
}
// loop through the data passed in.
foreach($data as $key => $value)
{
// if numeric key, assume array of rootNodeName elements
if (is_numeric($key))
{
$key = $rootNodeName;
}
// delete any char not allowed in XML element names
$key = preg_replace('/[^a-z0-9\-\_\.\:]/i', '', $key);
// if there is another array found recrusively call this function
if (is_array($value))
{
// create a new node unless this is an array of elements
$node = ArrayToXML::isAssoc($value) ? $xml->addChild($key) : $xml;
// recrusive call - pass $key as the new rootNodeName
ArrayToXML::toXml($value, $key, $node);
}
else
{
// add single node.
$value = htmlentities($value);
$xml->addChild($key,$value);
}
}
// pass back as string. or simple xml object if you want!
return $xml->asXML();
}
// determine if a variable is an associative array
public static function isAssoc( $array ) {
return (is_array($array) && 0 !== count(array_diff_key($array, array_keys(array_keys($array)))));
}
}
?>
Now with below responde I have tried problem is I get following output: <book>...</book> tags after each row.. then I tried 3 dimensional array now I get: <book><book>...</book></book> on the proper place but I have 2 of them.
This is the line where I have determine which is root on that array and that's why I get this output. But don't know how to change it : $xml = simplexml_load_string("<".key($data)."/>");
Thank you.
oci_fetch_array() will always return a single row, you need to call it until there are no more rows to fetch in order to get all of them:
while ($row = oci_fetch_array($refcur, OCI_ASSOC+OCI_RETURN_NULLS))
{
$library['book'][] = $row;
}
I would like to append html to an item in my array before echoing it on my page and am unsure how to go about doing it.
My data is put into an array like so:
$query = $this->db->get();
foreach ($query->result() as $row) {
$data = array(
'seo_title' => $row->seo_title,
'seo_description' => $row->seo_description,
'seo_keywords' => $row->seo_keywords,
'category' => $row->category,
'title' => $row->title,
'intro' => $row->intro,
'content' => $row->content,
'tags' => $row->tags
);
}
return $data;
I would like to perform the following on my 'tags' before returning the data to my view:
$all_tags = explode( ',' , $row->tags );
foreach ( $all_tags as $one_tag ){
echo '' . $one_tag . '';
The reason for doing this is that the tags in my database contain no html and are simply separated by commas like so news,latest,sports and I want to convert them into
sports ...
My reason for doing this here rather than when I echo the data is that I don't want to repeat myself on every page.
You could just create a function to be used everyhwere you are including tags in your output:
function formatTags($tags) {
$tmp = explode(',', $tags);
$result = "";
foreach ($tmp as $t) {
$result .= sprintf('%s',
urlencode(trim($t)), htmlentities(trim($t)));
}
return $result;
}
And whenever you do something like echo $tags; you do echo formatTags($tags); instead. View code should be separated from model code, which is why I would advise to not put HTML inside your array.
Well first of all you're overwriting $data with every run of the loop so only the final result row will be listed.
Once that's out of the way (fix with $data[] = ...), try this:
...
'tags' => preg_replace( "/(?:^|,)([^,]+)/", "$1", $row->tags);
...
