I want to integrate coinsecure api in my code, Here is the url for api which I have used.
Url : https://github.com/coinsecure/plugins/tree/master/master/php/SwaggerClient-php
Where there are two method to install/integrate API :
Using composer.
Manual process.
So I have select second one manual Process so based on document information
Download all file and add into my third part library folder.
And add require_ones autoload.php file.
Up to this step it'll fine but problem is now occur when I have perform action using this coin secure.
Suppose I want to get lowest rate over the last 24 hours so for that one bellow code is provided by api.
Code :
<?php
require_once(__DIR__ . '/vendor/autoload.php');
$api_instance = new Swagger\Client\Api\ExchangeTradeDataApi();
$accept = "accept_example"; // string | JSON, XML or CSV can be returned (Optional)
try {
$result = $api_instance->v1exchangemin24Hr($accept);
print_r($result);
} catch (Exception $e) {
echo 'Exception when calling ExchangeTradeDataApi->v1exchangemin24Hr: ', $e->getMessage(), PHP_EOL;
}
?>
And when I run this code it'll give me error as below :
[404] Error connecting to the API
(https://api.coinsecure.in/v1/exchange/max24Hr)
Can any one have idea why it give me error..?
Strange, there's an extra / in your URL before the v1 causing a 404 error. Instead it should be https://api.coinsecure.in/v1/exchange/max24Hr
Looks like their PHP library is hard coded wrong.
From their github library line 76
if ($apiClient == null) {
$apiClient = new ApiClient();
$apiClient->getConfig()->setHost('https://api.coinsecure.in/');
}
Then they include the / again on line 136
$resourcePath = "/v1/exchange/ask/low";
Notice how the base url ends with a / and the path starts with a /. You can change it yourself and it should work, but I bet the other calls in the library are messed up too. Maybe let them know so they can correct the library.

I am using a php mysql based crm software which is made using Codeigniter.
I don't have any knowledge about Codeigniter.
I just customized it as per my requirements.
Whenever I am trying to save any data I am getting this error.
While using in Xampp I did not get these errors.
When I put it online I started to get these. Also I tried to ignore PHP errors, warnings using
error_reporting(0);
in my controller/admin.php
This would just hide the errors and not ignore them and proceed to the redirected page after the save.
If anything else is needed please let me know.
Undefined index -- that's the error you need to resolve here. You're most likely trying to access a property of $_GET or $_POST using an incorrect key name.
For the sake of debugging, try this:
if(isset($_GET['keyname'])) {
$myObj->prop = $_GET['keyname'];
} else {
show_error('No value set for keyname', 500);
}
I'm making a lot of assumptions about your code here, replace keyname with whatever you are trying to access.
For reference, you should probably switch to using the CodeIgniter Input Class to get values from GET/POST.
Sadly, one plugin is causing me problems. It works great on one website but gives me an error on another website.
this is the error:
simplexml_load_file() [function.simplexml-load-file]: http://steamcommunity.com/profiles/76561197971691194/?xml=1:1: parser error : Document is empty
XenForo_Application::handlePhpError() in Steam/ControllerPublic/Register.php at line 117
If I go there, this is the code:
// Get User Profile Data
$id = $session->get('steam_id');
$xml = simplexml_load_file("http://steamcommunity.com/profiles/{id}/?xml=1");
if(!empty($xml)) {
$username = $xml->steamID;
$avatar = $xml->avatarFull;
The link is valid, you can try yourself and let's say go here: steamcommunity.com/profiles/76561197971691194 or http://steamcommunity.com/profiles/76561198041253738
Really need help, this is the only thing that is blocking me from starting the website!
That probably means that your host is blocking outbound HTTP requests.
Ask them to stop that, or find a better host.
I have found that one common reason for the error is an exception being thrown from within an exception handler. I'm quite sure this doesn't happen in the application I'm trying to debug... But I've put all the initialization processing lines at the top of index.php in a try/catch.*
It can apparently also happen because some things cannot be serialized to be stored in a session. At most this application stores arrays into the session (quite a bit), but I'm confident that it doesn't store anything too out of the ordinary in it.
Someone commented that it happened to them because their primary key needed to be CHAR(32) instead of INT(11). The PK's in this app are all INTs.
Other suggestions are that it could be a problem with PHP 5.3.3 fixed in 5.3.6, full disk, and a need to typecast a SimpleXML value. We do happen to be running PHP 5.3.3, but upgrading would have to be a last resort in this case. It hasn't always been doing this.
UPDATE/NOTE: I actually can't reproduce the error myself, only see it happening in the logs, see below paragraph for where I believe the error is happening...
* From the error logs, it seems likely that at least one place it is happening is index.php. I am deducing this only because it is indicated in some entries by a referring URL. The try/catch code is currently only around the "top" initialization portion of the script, below that is mostly the HTML output. There is some PHP code in the output (pretty straightforward stuff though), so I may need to test that. Here is the catch part, which is not producing any output in the logs:
} catch (Exception $e) {
error_log(get_class($e)." thrown. Message: ".$e->getMessage(). " in " . $e->getFile() . " on line ".$e->getLine());
error_log('Exception trace stack: ' . print_r($e->getTrace(),1));
}
Would really appreciate any tips on this!
EDIT: PHP is running as an Apache module (Server API: Apache 2.0 Handler). I don't think there are any PHP accelerators in use, but it could just be that I don't know how to tell. None of the ones listed on Wikipedia are in phpinfo().
As far as I can tell the MPM is prefork. This is the first I'd ever looked into the MPM:
# ./httpd -l
Compiled in modules:
core.c
prefork.c
http_core.c
mod_so.c
The problem
In short you have a exception thrown somewhere, you have no idea where and up until now you could not reproduce the error: It only happens for some people, but not for you. You know that it happens for other people, because you see that in the error logs.
Reproduce the problem
Since you have already eliminated the common reasons you will need to reproduce the error. If you know which parameter will cause the error it should be easy to locate the error.
Most likely it is enough if you know all the POST/GET parameters.
If you can't reproduce with just these, you need to know additional request headers. Such as user agent, accept-encoding,...
If you still can't reproduce, then it becomes very difficult: The error may depend on a state (a session), the current time, the source ip address or the like.
The custom log method
Let's start simple: To get all parameters you can write in the very beginning of the affected php file something like:
file_put_contents("/path/to/some/custom_error_log", date()."\n".print_r(get_defined_vars(), true), FILE_APPEND | LOCK_EX);
Don't forget that the custom_error_log file must be writable to your php application. Then, when the error occurs in the error log, find the corresponding lines in your custom_error_log file. Hopefully there are not to many requests per second so that you can still identify the request. Maybe some additional parameters in the error log like source ip can help you identify the request (if your error log shows that).
From that data, reconstruct a request with the same POST/GET parameters.
The tcpdump method
The next option that is very simple as well, but requires you to have root-access on your target machine is to install tcpflow. Then create a folder, cd into that folder and simply execute (as root) tcpflow "port 80". The option (port 80) is a pcap filter expression. To see all you can do with that, see man pcap-filter. There is a lot what these filter expressions can do.
Now tcpflow will record all tcp connections on port 80, reconstruct the full data exchange by combining the packages belonging to one connection and dump this data to a file, creating two new files per connection, one for incoming data and one for outgoing data. Now find the files for a connection that caused an error, again based on the timestamp in your error log and by the last modified timestamp of the files. Then you get the full http request headers. You can now reconstruct the HTTP request completely, including setting the same accept-encoding, user-agent, etc. You can even pipe the request directly into netcat, replaying the exact request. Beware though that some arguments like a sessionid might be in your way. If php discovers that a session is expired you may just get a redirect to a login or something else that is unexpected. You may need to exchange things like the session id.
Mocking more things
If none of this helps and you can't reproduce the error on your machine, then you can try to mock everything that is hard to mock. For example the source ip adress. This might make some stunts necessary, but it is possible: You can connect to your server using ssh with the "-w" option, creating a tunnel interface. Then assign the offending ip adress to your own machine and set routes (route add host ) rules to use the tunnel for the specific ip. If you can cable the two computers directly together then you can even do it without the tunnel.
Don't foget to mock the session which should be esiest. You can read all session variables using the method with print_r(get_defined_vars()). Then you need to create a session with exactly the same variables.
Ask the user
Another option would be actually ask the user what he was doing. Maybe you can follow the same steps as he and can reproduce.
If none of this helps
If none of that helps... well... Then it gets seriously difficult. The IP-thing is already highly unlikely. It could be a GEO-IP library that causes the error on IPs from a specific region, but these are all rather unlikely things. If none of the above helped you to reproduce the problem, then you probably just did not find the correct request in all the data generated by the custom_log_file-call / tcpflow. Try to increase your chances by getting a more accurate timestamp. You can use microtime() in php as a replacement for date(). Check your webserver, if you can get something more accurate than seconds in your error log. Write your own implementation of "tail", that gives you a more accurate timestamp,... Reduce the load on the system, so that you don't have to choose from that much data (try another time of day, load of users to different servers,...)
circle the problem once you can reproduce
Now once you can reproduce it should be a walk in the park to find the actual cause. You can find the parameter that causes the error by trial and error or by comparing it to other requests that caused an error, too, looking for similarities. And then you can see what this parameter does, which libraries access it, etc. You can disable every component one by one that uses the parameter until you can't reproduce anymore. Then you got your component and can dive into the problem deeper.
Tell us what you found. I am curious ;-).
I had such an error, too. Found out that I returned a sql object in my session class (that was used by the session_handler) instead of returning nothing or at least not the sql object. First look into your _write and _read methods, if you too return some incorrect stuff.
Notice: ... Unknown on line 0 - How to find correct line, it's NOT "line 0"
I realize this question has already been answered, but I'll add this since it may help someone:
I managed to (unintentionally) produce errors without a stack frame from a function which used its own error handler to maintain control of execution while calling a potentially "dangerous" function, like this:
// Assume the function my_error_handler() has been defined to convert any
// PHP Errors, Warnings, or Notices into Exceptions.
function foo() {
// maintain control if danger() crashes outright:
set_error_handler('my_error_handler');
try {
// Do some stuff.
$r = danger();
} catch (Exception $e) {
$r = 'Bad Stuff, Man!';
}
restore error_handler();
return $r;
}
The "untraceable failure" would happen at the end of the program execution if the logic in "Do some stuff" returned from foo() directly, bypassing the call to restore_error_handler(). What I took away from the experience is this:
PHP maintains a stack of error handlers which gets deeper/taller with each call to set_error_handler().
Bad Stuff can happen if you push error handlers onto the stack and don't clean up after yourself before the program exits "normally".
This was a tough bug to isolate - I basically narrowed the problem down to the above function and then stared at it until my eyes bled.
So how would I have tracked this down, knowing what I know now? Since I don't know of any way to inspect the PHP error handler "stack" directly, I'm thinking it might make sense to use a Singleton object to encapsulate all set/restore operations for PHP error handlers. At least then it would be possible to inspect the state of the Singleton before exiting the program normally, and if "dangling" error handlers are detected to generate a sensible failure/warning message before PHP freaks out.
Instead of wrapping code in a try/catch block, what happens when you register an exception handler? Clearly your try/catch block is not catching the exception, thus resulting in the errors logged to Apache. By registering a handler, you can be sure any uncaught exception is handled.
Also, if you're using namespaces in your application, make sure you write \Exception in your catch block (or include the Exception class via a use statement).
This may be a little late but one issue I discovered when moving a site from a local to a remote server. I was using Concrete5 cms had developed my site locally(windows 8 in xampp) and then uploaded to a remote server running Cent 0S
Windows mysql by default is case insensitive and created a lower case database. Once this was uploaded to the remote server I received the "Exception thrown without a stack frame in Unknown on line 0?"
I then corrected the database tables case and my site started working again.
For us, this error was due to inadvertently serializing SimpleXML objects.
If you are using SimpleXML objects with 5.3.3, make sure you are are casting the node values to whatever you need (e.g. string) if you are serializing the values in the session.
Before:
$token = $response->Token->Value;
/* token saved in session, results in line 0 error */
After:
$token = (string) $response->Token->Value;
/* token saved in session, no error */
I had completely the same error. A very spacial case: if you connect an unnamed function (closure) hook to an object instance's hook point. After that you try to serialize this object.
I had the same error after filling the Illuminate Eloquent model's Fillable property incorrectly. Note the last 3 elements of the array, one is missing a coma.
protected $fillable = [
'budget',
'routestatus' ,
'userroutenumber'
'totalmovingseconds',
'totalidleseconds'
];
I had the same error, it appeared upgrading server from centos 5 to centos 6 and downgrading PHP from 5.4 to 5.3. Actual issue was PHP apc, not configured properly. Check your APC. I was using Symfony2, so you might find some help at Symfony Unable to allocate memory for pool
one simple way to produce this error is an old server with register_globals = On. then you only need two lines of code:
<?php
$_SESSION["my_var"] = "string";
$my_var = new MyClass(); //could be any class, i guess
?>
as soon as you reload this page once, you'll get the Exception thrown without a stack frame in Unknown on line 0 - error. seems like there is a conflict between the instance of the class and the (session) variable.
at least this is how i got this annoying error which is so hard to debug.
This problem occurred for me when I changed the namespace on a few Symfony bundles. Deleting the files in the the symfony cache directory fixed the issue.
Likely you have a corrupt/inconsistent table in the database. Try dumping the database. If you get a error that's the time. Repair that table and the issue should go away.
It is for this reason why clean install works. The clean install is just that clean.
mysqlcheck should work but if it does not show and issue still do above.
I have the following PHP code on a web page:
$wsdl_url = "someURL?wsdl";
try {
$client = new SoapClient($wsdl_url, array('login' => 'mylogin','password' => 'mypassword'));
$client->myWebMethod(); // <-- problem call
} catch (Exception $e) {
echo "none";
}
It's a basic call to a web service. The problem is that when an error is thrown on the line $client->myWebMethod(), echo "none" is not printed. In fact, nothing in the catch block runs. Hence, I don't think the exception is being caught.
A fatal error is displayed on the web page.
Question: Any ideas on why this is happening? I expected all exceptions to be caught and handled with this code. But what I'm getting is that the fatal error is being displayed on the page. Maybe web services are handled differently?
EDIT: the error is that it's missing a bunch of required parameters. if I add the parameters the call works fine. I am purposely omitting the parameters to get the error, so i would know how to handle it.
The error is something like: Fatal error: SOAP-ERROR: Object hasn't 'myparameter1'
Thanks in advance.
I got the same exact problem this morning while running a custom module for Drupal which required an external SOAP Web Service. To be honest, I'm not quite sure how I solved the problem.
Turns out it was all about clearing my Web Server's cache that had to do with the respective WSDL. In your tmp/ folder you will find various files named wsdl-yourservice-etc. Delete them and it should be OK. If not, the problem lies in the code and more specifically in the sequence and syntax of the arguments passed to the WSDL.
I hope I helped.
Unfortunately, this is not a catchable error.
However, you can check if the soap extension is loaded before trying to instantiate it by calling get_loaded_extensions with something along the lines of:
if (in_array('soap', get_loaded_extensions())) {
// it's loaded!
}
