PHP - Json_encode() Outputs Weird Characters
I have a piece of code that outputs json as you can see from the example below it add \ / in front of urls & for ' it turns it into ' is there something i can do to correct this?
Code: [Select] if (mysqli_num_rows($r) > 0) { // Available. while ($row = mysqli_fetch_array($r, MYSQLI_ASSOC)) { $results[] = array( 'blog_id' => ($row['ID']), 'post_date' => ($row['pd']), 'post_title' => ($row['post_title']), 'article_img' => ('http://www.socialnewsoffice.com/uploads/'.$row['article_img']), 'post_content' => ($row['post_content']), 'tags' => ($row['tags']), 'views' => ($row['views']), 'categorie_id' => ($row['categorie_id']), 'post_url' => ($row['post_url'])); } echo $json = Pretty_JSON(json_encode($results)); it outputs Code: [Select] [{ "blog_id":"3", "post_date":"Thu, 1 March 2012", "post_title":"Facebook's New Fan Page Learn How To Use Features", "article_img":"http:\/\/www.socialnewsoffice.com\/uploads\/17963.jpg", "post_content":"<p>This week saw the release of Facebook's latest functionality changes (Timeline for Businesses) that will shape the future of how businesses will market their campaigns, through the social media giant Facebook.

I made a website to keep track of where I am in various manga. I noticed that sometimes the title I grab looks OK when rendered on the page but in the database it's weird looking
I did a for ($x=0; $x<strlen($title); $x++) loop and dumped $x, char at $ pos and ord of char: 0 = T = 84 1 = h = 104 2 = e = 101 3 = = 32 4 = D = 68 5 = e = 101 6 = m = 109 7 = o = 111 8 = n = 110 9 = = 32 10 = K = 75 11 = i = 105 12 = n = 110 13 = g = 103 14 = � = 226 15 = � = 128 16 = � = 153 17 = s = 115 18 = = 32 19 = D = 68 20 = a = 97 Is there some nifty built in function for converting that weird stuff to a regular apostrophe (and convert any other weird stuff)? I mean, I can write a filter to look for 226/128/153 and replace with ' but I'm sure there must be a proper way to handle that stuff. Thanks! I have a weird problem with an md5() function. I am trying to write a token system, (just for my own fun really), going off an example guestbook I got help with from here. What my main aim is to allow the moderator for the guestbook to receive an email (which is working in its own context), with a link to a script page that checks into the database and when the user clicks on the link it allows the message in the guestbook to be shown. But when I try md5() the ip address of the user it works, but I thought if that same user went in and did another post, it would come up with the same checksum, causing quite bad problems to be honest. So I thought about using something like: $time = microtime(); $checksum = md5($ip,$time); But this keeps coming up with say: Quote 3RiYD Is there anyway of getting around this at all? To show a real value as I am sure this wont work, any helps greatly appreciated, Jeremy http://pixpresso.mycyberlove.com/ This is my test hosting for this site I'm making. Navigation and facebook login are almost done. So, the problem is that after facebook login URL is http://pixpresso.mycyberlove.com/#_=_ Why is this? Is this bad, should I and can I remove this? <?php $i = 2; $i = $i++; echo $i; ?>Output of above code is 2. <?php $i = 2; $p = $i++; echo $i; ?>Output of above code is 3. Why this difference? I mean how these codes are processed to give an output?
<?php
include('header.php');
require('dbcon/dbcon.php');
// if fields in form are set and submitted, check if user exists and is logged in or not
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$username = $_POST['username'];
$password = $_POST['password'];
$user_query = $pdo->query("SELECT * FROM profiles001 WHERE username = '$username'");
$row = $user_query->fetchAll(PDO::FETCH_ASSOC);
// if username and password match, init session and redirect to another page.
if ($row == 1 && password_verify($password, $row['password'])) {
$_SESSION['logged_in_user'] = $username; // set to IDnum later on...
$_SESSION['username'] = $username;
// check if the user is logged in
// if so, redirect to main page for logged-in users.
if (isset($_SESSION['logged_in_user'])) {
$_SESSION['logged_in_user'] = TRUE;
header('Location: main.php');
} else {
// not logged in, keep on same page...
session_destroy();
exit();
}
} else if ($username != $row['username'] || $password != $row['password']) {
echo var_dump($row); echo var_dump($row['password']); echo var_dump($row['username']); echo var_dump($row['email']);
echo "Incorrect username or password.";
}
}
?>
This code is responsible for authenticating the user upon logging in. I went ahead and updated the mysqli portion to PDO. As you can see I var_dump some variables near the end. Variable $row prints out as array(1) { [0]=> array(9) { ["username"]=> string(4) "test" ["password"]=> string(60) "$2y$10$uQEUsIwm0usWyZjWk/vo8e90e867oPLBu3ThKCk1aUseMcQuuHrVq" ["avatar"]=> string(15) "assets/soap.jpg" ["doc"]=> NULL ["las"]=> NULL ["email"]=> string(13) "test@test.org" ["c_status"]=> string(1) "0" ["account_age"]=> NULL ["bio"]=> string(4) "test" } }. The other three print out as NULL. What exactly is going on here? Hey everyone. So i'm trying to json_encode one of my arrays like such:
heres an example of how the array is being created (From the array results, everything seems to be fitting OK into the actual array creation) but it's just the actual array creating a multi demension after each result.
$num = 1;
$num2 = 1;
$i = 0;
if ($num > 0)
{
$array[$i][1] = 40;
}
if ($num2 > 0)
{
$array[$i][2] = 50;
}
++$i;
I'm trying to achive this:
var array_one_results = new Array(); array_one[1][0] = 40; array_one[1][0] = 50; array_one[2][1] = 40; array_one[2][1] = 50;right now, this is my results: var array_name = new Array(); array_name["0"] = new Array();array_taken["0"]["0"] = "10"; array_taken["0"]["1"] = "20"; array_name["1"] = new Array();array_taken["1"]["0"] = "10"; array_taken["1"]["1"] = "20"; array_name["2"] = new Array();array_taken["2"]["0"] = "10"; array_taken["2"]["1"] = "20"; array_name["3"] = new Array();array_taken["3"]["0"] = "10"; array_taken["3"]["1"] = "20"; array_name["4"] = new Array();array_taken["4"]["0"] = "10"; array_taken["4"]["1"] = "20";It's creating a new array for each. If anyone could help me through this, i'd really appreciate it. I'm encoding it with this:
function js_str($s)
{
return '"'.addcslashes($s, "\0..\37\"\\").'"';
}
function js_array($array, $keys_array)
{
foreach ($array as $key => $value)
{
$new_keys_array = $keys_array;
$new_keys_array[] = $key;
if(is_array($value))
{
echo 'array_name';
foreach($new_keys_array as $key)
{
echo '["'.$key.'"]';
}
echo ' = new Array();';
js_array($value, $new_keys_array);
}
else
{
echo 'array_taken';
foreach($new_keys_array as $key)
{
echo '["'.$key.'"]';
}
echo ' = '.js_str3($value).";\n";
}
}
}
Hey guys, I am having a bit of trouble, I am using the function time() to insert the time the form was submitted to the database. It inserts the data like this: 1301407145 I have a date column. I am then trying to echo the date the person submitted the form from the database using: <?php echo date('d-M-Y h:i A', $date); ?> the $date gets used with the mysql fetch array and for some reason it outputs it as: 01-Jan-1970 01:00 AM Can someone explain to me why? I am using this to insert into the db. $date = time(); and then the $date goes into the statement. mysql_query("INSERT INTO messages (reciever, sender, subject, message, date) VALUES ('$reciever', '$user', '$subject', '$message','$date')") or die (mysql_error()); Why isnt it working? Hi guys, I have a simple query he $sql="SELECT user_id FROM $tbl_name WHERE email='$loginuseremail' AND password='$loginpassword'"; $result=mysql_query($sql); $row = mysql_fetch_assoc($result); //START SESSION session_start(); $_SESSION['username']=$loginuseremail; $_SESSION['user_id']=$row; echo $_SESSION['user_id']; It should obviously output an ID number but instead I just get the word 'Array'. If I remove the mysql_fetch_assoc() I just get 'Resource ID #4'. Can anyone point me in the right direction? Thanks! Reasons to use json_last_error() is obvious when decoding, but was not so to me when encoding. Looking at the documents, malformed UTF-8 characters will result in an error. The examples given show encoding a string, however, an array with an index value which is malformed UTF-8 characters will result in the same error. Are there other cases which json_encode() will result in error? Why would one actually want to use json_encode() on a string? Sorry if this is a silly question lol. I want to know if there is an online tool I can use to check and see what PHP code will ouput server side. For example: <?php $tomorrow = mktime(0, 0, 0, date("m") , date("d")+1, date("Y")); ?> I am just trying to use Associate array in another php file through session.
file1.php <?php $age = array(); $_SESSION["age"] = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43"); foreach($_SESSION["age"] as $x => $x_value) { echo "Key=" . $x . ", Value=" . $x_value; echo "<br>\n"; } ?> OUTPUT: Key=Peter, Value=35 Key=Ben, Value=37 Key=Joe, Value=43 file2.php <?php session_start(); foreach( $_SESSION["age"] as $x => $x_value) { echo "Key=" . $x . ", Value=" . $x_value; echo "<br>\n"; } ?> OUTPUT: PHP Notice: Undefined index: age in session.php on line 3 PHP Warning: Invalid argument supplied for foreach() in session.php on line 3 Why am I getting this error? Above is just example I tried to demonstrate for asking question for other issue, unfortunately I got new error in this example. But actual issue was, I was trying to plot graph using library which requires only Associate array, where the data is formed in file1.php. But I get only last index value displayed in file2.php even in graph or in echo. I don't understand why other values are not displayed in file2.php Please point me what is going wrong, Thanks. Good morning,
I am trying to convert a mssql query into json format so that I can then later pass this through google's visualisation api. The query and encoding seems to be working but the encode returns NULL.
I have checked the normal gotcha's of making sure its utf8 encoded and that I have used a version of PHP that has the encode (using php 5.3.19).
Can any one help me with getting the encode to work.
PHP CODE:
<?php Hello
I am having an issue with encoding an array to JSON, my array seems to be formed correctly but when I try and echo the json_encode version I get "null". I echo the JSON error code and it is "0" indicating no issue..
I have read that non UTF-8 characters can be an issue, but this is simple data, no strange characters... but I added the utf8_encode anyway....
Here is my code:
$dataArray = array(
'title' => 'Test Item',
'icon_url' => 'http://url/api/testimage.jpg',
'item_id' => '12345',
'expiration' => 600
);
utf8_encode($dataArray);
$responsArray = array(
'success' => '1',
'data' => $dataArray
);
utf8_encode($responsArray);
header('Content-type: application/json');
echo print_r($responsArray);
echo json_encode ($responseArray);
echo json_last_error();
when trying to decode a array of rows taken from my database I found that the json_encode function doesn't allow you to present you array as (with brackets [ ])
[{"name":"Destramic"}]
but returns the array as (without brackets [ ])
{"name":"Destramic"}
I looked into the documentation and it doesn't seem as if php offer such a way of having bracket which Is a bit of a problem with passing to jquery (which I've found using their autocomplete plugin)
this has resulted in me having to add brackets myself
$data = "[" . json_encode($rows2) . "]";does anyone know if you can encode it with the brackets or readable for jquery...thank you Hi All I got some help to write this code and it is not working because i get the error ( ! ) Parse error: syntax error, unexpected '{' in C:\wamp\www\blackrain\Resources\json-gen.php on line 14 Here is the php code Code: [Select] <?php error_reporting(-1); ini_set('display_errors',1); $link = mysql_connect('localhost', 'root', ''); if (!$link) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully<br />'; mysql_select_db("php"); $arr = array(); $rs =mysql_query("SELECT `id`, `title`, `author`, `date`, `imageUrl`, `text` FROM `items`"); while($obj = mysql_fetch_array($rs,MYSQL_ASSOC) { $arr[0] = $obj['id']; $arr[1] = $obj['title']; $arr[2] = $obj['author']; $arr[3] = $obj['date']; $arr[4] = $obj['imageUrl']; $arr[5] = $obj['text']; } //numbering the array indexes, will only return 5 array indexes EVER.

Any help is much appreciated. Hello, I am new to pHp and javascript languages and I am trying to do some math calculations in pHp, then display the results with google charts. However, I got stuck with inserting data from pHp using json_encode. It works for the most simple array, with using 2 values. When using array of arrays, it does not work. I believe it could be a syntax errors with all those brackets but I could not figure it out. Thanks for any ideas!
<?php
// some arrays with dim 2x2
$testarr0 = array( 0.1, 2.5);
$testarr = array( 1.0, 3.5);
$testarr = array( $testarr0, $testarr ) ;
// this is how it looks in pHp
$json = json_encode($testarr);
echo($json);
echo '<br/>';
echo json_encode($json);

Dear all hello. I am facing a major issue with greek characters. Here is the php script: Code: [Select] <?php $connect = mssql_connect($db_server,$db_username,$db_password) or die("0001"); mssql_select_db($wf_db) or die("0002"); $sql_a = "SELECT [ID],[WASTE_SN] FROM [Webforms].[dbo].[Waste_Types] ORDER BY [WASTE_SN] ASC"; $waste_name = array(); $waste_id = array(); $query_a = mssql_query($sql_a) or die("0003"); while ($row = mssql_fetch_assoc($query_a)){ $waste_name[] = $row['WASTE_SN']; $waste_id[] = $row['ID']; } mssql_close($connect); $final_array = array( "waste_name" => $waste_name, "waste_id" => $waste_id ); $json = json_encode($final_array); echo $json; ?> Json_encode returns null for all values of array $waste_name when greek words are found. When I use print_r($waste_name), i can see all words fine. I've tried almost everything, including utf8_encode without results. Any help will be really appreciated! I have a function where I am returning a few different arrays into one return json_encode(); but how would I do this? I'm bulling an array from 2 different database tables, and I can't join or union these, because I am actually going to have quite a few different calls that needs to call into other areas. Anyway, My 2 variables are,' $names and $posts If I put one of these in the return json_encode($posts); like that, then the $posts show up fine while the names of course display Undefined, and if I put in return json_encode($names); then my code works for the names to be displayed but anything in the posts of course is undefined, how do I put these two together? Thanks |
