file_get_contents php and json_decode error

问题

I am facing a weird problem with file_get_contents and decoding to json the result. I have to tell you that this code was fully functional in other server.

I am trying to decode this json: http://mediarupt.com/GET/categorized_services_for_supplier.php?suppliersID=10

into this page: http://mediarupt.com/kostas.php

The code for kostas.php is this:

<?php 
$servicesJSON = file_get_contents("http://mediarupt.com/GET/categorized_services_for_supplier.php?suppliersID=10");
$ForeignKeys = (object)array();
$ForeignKeys->ServicesList = json_decode($servicesJSON, true);

echo "error: " . json_last_error();

?>

<select name="servicesID" id="servicesID">
    <option id="serviceID_0" value="0" rel="0" style="font-style:italic;">Select a category...</option>
<?php foreach($ForeignKeys->ServicesList['categorized_services'] as $value){ ?>
    <option id="serviceID_<?=$value['servicesID']?>" value="<?=$value['servicesID']?>" rel="<?=$value['hasStoresList']?>"><?=$value['serviceName']?></option>   

<?php } ?>

</select>
<?php

echo '<br><br>The result of file_get_contents ($servicesJSON): '.$servicesJSON;

?>

Code for categorized_services_for_supplier.php:

<?php header('Content-Type: application/json');
    require('../settings/dbli.php');

    $table = array();
    $suppliersID = "0";

    if(isset($_GET['suppliersID']) && $_GET['suppliersID']!=NULL && $_GET['suppliersID']!='' ){  $suppliersID = $SQLConn->real_escape_string($_GET['suppliersID']); }
    $query = "SELECT DISTINCT Services.servicesID, serviceName, servicePrice, hasStoresList FROM Services, ServicesList WHERE Services.servicesID = ServicesList.servicesID AND suppliersID = '$suppliersID' AND  status = '1' AND deleted = '0'";

    $result = $SQLConn->query($query);  
     while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
        $tempArray = array();
        foreach($row as $key => $value){
            $tempArray[$key] = $value;                      
        }
        array_push($table,$tempArray);
     }
     $arr = array( "categorized_services" => $table);
    echo json_encode($arr);
?>

I receive error 4 as latest json error, which means that I have JSON_ERROR_SYNTAX. But I validate the json result with http://jsonlint.com/ and all seems to be ok.

Also, both pages are UTF-8 with BOM disabled. You can access php configurarion here: http://mediarupt.com/phpinfo.php

I hope to find the solution...

Thank you in advance

回答1:

The json is simply invalid.

In front of the first opening curly braces there is the following content (hex encoded) ef bb bf ef bb bf

It is the utf8 bom.

There is a question related to deal with exactly that, so I will not cover it here. Read up here:

How to remove %EF%BB%BF in a PHP string

and another one dealing specifically with json here:

Convert UTF-8 with BOM to UTF-8 with no BOM in Python

回答2:

Try to give JSON URL in the http://jsonlint.com/ and than copy the response and paste it in a file with BOM disabled you will notice that there is a strange small line in the beginning before the opening { bracket which is causing the issues
