i need to remove () backslash in my string when using echo json_encode()?
my example..
$song_url = 116e9155e0afc11555cf33dc9c9bd25d.mp3
$resmsg[] = array("Song_name"=>"$song_name","Song_URL"=>"http://www.kbmusique.com/songs/$song_url");
echo json_encode($resmsg);
my output is
[{"Song_name":"djigh araouioui","Song_URL":"http:\/\/www.kbmusique.com\/songs\/116e9155e0afc11555cf33dc9c9bd25d.mp3"}]
but i need as
[{"Song_name":"djigh araouioui","Song_URL":"http://www.kbmusique.com/songs/116e9155e0afc11555cf33dc9c9bd25d.mp3"}]
Is there a way to solve this? Thank you.
Your comment indicates that you just need to get a copy/pastable URL for testing.
Just parse the JSON and extract the piece of data you need from it. i.e. If you want a text representation of something, then convert the JSON to text, don't try to hack the JSON into a specific form.
You could do this in PHP with json_decode, in a browser with JSON.parse(), or just use a tool such as the Chrome JSONView extension.

I'm very new to PHP but have a good understanding of C,
When I want to access some post data on an API i'm creating in PHP I use:
$_POST['date_set']
to fetch a value being passed for date - This all works perfectly, however I read I should be fetching it like this:
$date_set = trim(urldecode($_POST['date_set']));
This always returns a 00:00:00 value for the date after it's stored in my DB.
When I access directly using $_POST['date_set'] I get whatever value was posted, for example: 2013-08-28 10:31:03
Can someone tell me what I'm messing up?
You should try it like,
$date_set = $_POST['date_set'].explode(' ');//('2013-08-28 10:31:03').explode(' ')
echo $date_set[1];
or
echo date('H:i:s',strtotime($_POST['date_set'])));
//echo date('H:i:s',strtotime('2013-08-28 10:31:03'));
If you are very new in php the Read date()
You only run urldecode over data is URL encoded. PHP will have decoded it before populating $_POST, so you certainly shouldn't be using that. (You might have to if you are dealing with double-encoded data, but the right solution there should be to not double encode the data).
trim removes leading and trailing white-space. It is useful if you have a free form input in which rogue spaces might be typed. You will need to do further sanity checking afterwards.
urldecode — Decodes URL-encoded string
Description
string urldecode ( string $str )
Decodes any %## encoding in the given string. Plus symbols ('+') are decoded to a space character.
urldecode: is used only for GET requests. you should be fine using $_POST['date_set'] only.
http://php.net/manual/en/function.urldecode.php
You'd better do this way
if(isset($_POST['date_set'])){
$date_set = $_POST['date_set'];
}
then you can use $date_set how you want.
If you still get 00:00:00 for $date_set, the problem is coming from the code which provide you the $_POST value.
I am taking user input sending it to server using jQuery ajax...after inserting user values in database I am sending response back to client as JSON string as following
echo '{"success":"true","data":"'.nl2br($a).'","type":"text"}';
as user input can contain new line, I am using nl2br so that all new line characters are converted to <br> and also know that JSON doesnt support multi line, thats why I am using nl2br....but parsing is failing at client side
pls tell me what the reason and how can I solve it?
parsing code var obj = jQuery.parseJSON(data);
You should be using json_encode, wich will generate a JSON string that contains \r\n for line breaks. Then you will have to replace each \r\n occurences by <br> tags.
echo str_replace('\r\n','<br>', json_encode(array("success"=>"true","data"=>$a,"type"=>"text")));
echo json_encode(array("success"=>"true","data"=>$a,"type"=>"text")
Use the php function json_encode rather then trying to set the encoding yourself. You'll save yourself a lot of trouble that way. http://php.net/manual/en/function.json-encode.php
nl2br() does not replace the line breaks, only inserts <br> before them.
As such, \n is being returned and therefore creating invalid JSON.
You should use json_encode() when creating JSON strings. For simplicity, you could simply use it on data:
echo '{"success":"true","data":' . json_encode(nl2br($a)) . ',"type":"text"}';
In another question, it was pointed out that using semantic markup can be a really clean way to pass data to an onclick function, along the lines of the code below.
I have a second question relating to passing JSON and having the receiving function recognize it as such. I have a PHP generated JSON value of [{"authed":"2012-03-04 17:24:24"},{"authed":"2012-03-04 11:44:38"}] that I need to pass to a function. echoing that straight into the <a> tag won't work, so I am using urlencode() to get:
click
Unfortunately, when I alert this out from popup(), I via the following code:
function popup(t) {
var auth = t.getAttribute('data-auth');
alert(decodeURI(auth));
}
I get
[{"authed"%3A"2012-03-04+17%3A24%3A24"}%2C{"authed"%3A"2012-03-04+11%3A44%3A38%22"}]
which JSON.parse() is unable to handle. Any suggestions on decoding/passing JSON using this pattern?
You need to use htmlspecialchars() to escape for html--like you should be doing for everything you echo out in html. (You are doing that right? To prevent generating invalid html?) Don't use urlencode(), which is for encoding parts of a url path or query parameter.
<?php
$data = array(array('authed'=>'2012-03-04 17:24:24'), array('authed'=>'2012-03-04 11:44:38'));
$jsondata = json_encode($data);
?>
<a data-auth="<?php echo htmlspecialchars($jsondata, ENT_COMPAT, 'UTF-8')?>" onclick="popup(this)">click</a>
I have a json_string in my database.
I echo and parse it to an object in javascript
I do
$.parseJSON('<?php echo $json_string;?>');
I get a json parse error.
What should I be doing?
This is my json_String
{"patches":[[{"diffs":[[1,"\u000a\u000a printhellon() {\u000a\u000a\u000a}d\u000a\u000a\u000a"]],"start1":0,"start2":0,"length1":0,"length2":26}],[{"diffs":[[0,") {\u000a\u000a\u000a}d"],[1,"s"],[0,"\u000a\u000a\u000a"]],"start1":15,"start2":15,"length1":11,"length2":12}],[{"diffs":[[0," {\u000a\u000a\u000a}ds"],[1,"d"],[0,"\u000a\u000a\u000a"]],"start1":16,"start2":16,"length1":11,"length2":12}]],"times":[1314489779299,1314489779408,1314489779581]}
I think JSON parsers don't like line breaks in strings for some reason. Parsing worked for me after removing the \u000a characters.
Edit: just like Brad said, it would be better to include the code directly as an object. Parsing JSON is usually more useful for data obtained using Ajax or something.
From your example, it appears like you're trying to insert PHP code into your javascript. You can't use PHP like that. PHP is server side, while Javascript runs in the browser after the page has been downloaded.
If you must get data from PHP to your javascript, you need to use AJAX. It's actually really easy with JQuery. Check out http://api.jquery.com/jQuery.ajax/
Could some one please help me out on this I have the following json string
string(1223) "YAHOO.Finance.SymbolSuggest.ssCallback({"ResultSet":{"Query":"google","Result":[{"symbol":"GOOG","name": "Google Inc.","exch": "NMS","type": "S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"GOOG.MX","name": "GOOGLE-A","exch": "MEX","type": "S","exchDisp":"Mexico","typeDisp":"Equity"},{"symbol":"GGQ1.F","name": "GOOGLE-A","exch": "FRA","type": "S","exchDisp":"Frankfurt","typeDisp":"Equity"}]}})"
But I cannot seem to get anywhere with it. Basically I want to just loop out the the results which are
[{"symbol":"GOOG","name": "Google Inc.","exch": "NMS","type": "S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"GOOG.MX","name": "GOOGLE-A","exch": "MEX","type": "S","exchDisp":"Mexico","typeDisp":"Equity"},{"symbol":"GGQ1.F","name": "GOOGLE-A","exch": "FRA","type": "S","exchDisp":"Frankfurt","typeDisp":"Equity"}]
Sorry my question is how can I loop or even print the first result for example
{"symbol":"GOOG","name": "Google Inc.","exch": "NMS","type": "S","exchDisp":"NASDAQ","typeDisp":"Equity"}
Your string is not JSON, it is JSON-in-Script. Notice the fragment that says:
YAHOO.Finance.SymbolSuggest.ssCallback(...)
When a browser receives the above mentioned script (actually a javascript code) it will call the YAHOO.Finance.SymbolSuggest.ssCallback function, passing the JSON data as the argument.
You did not mention if you want to access the JASON data on the server side or client? It its server side (PHP) then you can use regular expressions or string replacement functions to extract the portion you like. The you can use json_decode() function to convert the resulting string into an associative array.
Edit ----
A quick and dirty hack for converting JSONP to JSON:
<?php
$text = 'YAHOO.Finance.SymbolSuggest.ssCallback({"ResultSet":{"Query":"google","Result":[{"symbol":"GOOG","name": "Google Inc.","exch": "NMS","type": "S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"GOOG.MX","name": "GOOGLE-A","exch": "MEX","type": "S","exchDisp":"Mexico","typeDisp":"Equity"},{"symbol":"GGQ1.F","name": "GOOGLE-A","exch": "FRA","type": "S","exchDisp":"Frankfurt","typeDisp":"Equity"}]}})';
# //CONVERT JSONP to JSON\\
$text = preg_replace('/.+?({.+}).+/', '$1', $text);
# \\CONVERT JSONP to JSON//
$data = json_decode($text);
var_dump($data);
var_dump($data->ResultSet->Result[0]);
var_dump($data->ResultSet->Result[0]->symbol);
var_dump($data->ResultSet->Result[0]->name);
# etc etc
?>
Your result is not just a JSON string, it's a JSON string prepended by a call to a JSON function. This is quite certainly a JSONP call.
You must write the YAHOO.Finance.SymbolSuggest.ssCallback(data) javascript function and get the Json there. Check the JSONP query, you should be able to alter the name of this backreference function if you want another name, it's usually on of the parameter in the GET query.
Now you are maybe calling it directly from PHP and you are not in js envirronment. so you must write something in your PHP code to remove the YAHOO.Finance.SymbolSuggest.ssCallback( part and the ) at the end before parsing it as JSON data..
