I am developing a website using PHP and mongodb. I access the mongodb with PECL-mongo, and have run into an annoyance. Every now and then, I get an error like this (I've anonymized the paths)
Fatal error: Uncaught exception 'MongoCursorException' with message 'couldn't get response header' in
/PATH/index.php:38 Stack trace: #0
/PATH/index.php(38): MongoCursor->rewind() #1
/PATH/template.inc(29): get_sidebar() #2
/PATH/index.php(13):
require_once('PATH/...') #3 {main} thrown in PATH/index.php on line 38
According to the documentation, this means:
The driver could not fetch a reply header from the database, so it
gave up. Check if the database is still up and the network is
connected and try the query again.
But I know that the database is up because I am doing this locally on my own machine over loopback. No connection is made to the outside world.
Simply trying again often works. Is this a possibly a bug in PHP's driver for mongo? Could this be a "miscompile" issue (I compiled from source, but with very benign flags, -march=native -O2)?
Has anyone seen this before?
Searching around, I only see references to some stupid facebook game having the same error.
EDIT: I just downgraded my PECL driver to version 1.1.4 and so far, the problem seems have gone away. So this may simply be a bug in the 1.2.x series. If anyone can shed any light on it, that would be great.
EDIT: I am not doing anything complex here, the code that is having the issue litterally looks like this:
$m = new Mongo();
$collection = $m->my_db->collection;
$results = $collection->find(array("favorite"=>true))->limit(5);
i solved this problem with get new version mogodb.dll

Basically the project I was assigned requires me connecting to an Exchange 2010 SP2 server via PHP. I have researched several possibilities and found that SOAP is the most accessible approach (I could be wrong, however) and have been basing the majority of my code on this link: https://www.howtoforge.com/talking-soap-with-exchange
I got up to the following part:
print_r($client->__getFunctions());
When I tried to test it out I got an error as followed:
Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'SERVER ADDRESS.WSDL' : failed to load external entity "SERVER ADDRESS.WSDL" in C:\xampp\DIRECTORY:4 Stack trace: #0 C:\xampp\DIRECTORY(4): SoapClient->SoapClient('SERVER ADDRESS') #1 {main} thrown in C:\xampp\DIRECTORY on line 4
Line 4 being :
$client = new SoapClient($wsdl);
I have researched the possible issues regarding this, enabled all the required things for PHP and researched other alternatives but I think the issue lies in the connection itself between Exchange and the code (connecting directly through the browser works fine).
To summarize my issues with a question: Is there a possible compatibility issue between the latest PHP and cURL (currently 7.2.1. and 7.56.0 respectively) and Exchange 2010?
Would it also be possible to maybe receive other suggestions on how I can tackle this issue?
I am trying to shadow a live website to my local machine, I have finished all the copy thing for home folder and database from cpanel.
So far, I didn't make any change on code part, and just installed xampp and set up phpmyadmin.
after I set the localhost, and loaded the local page then below message displayed.
Fatal error: Uncaught Error: Call to undefined function
mysql_connect() in F:\htdocs\ramtaps\includes\php_library.inc:41 Stack

So I looked into the code and it said that mysql_connect is deprecated.
I am pretty new one this field and tried few things and they didn't work so far.
If anyone advises me regarding on this, I would really appreciate.
although you did not mention your PHP version, it is obvious that you are using PHP with version > 7
mysql_connect was removed in PHP 7.0.0 and above
http://php.net/manual/en/migration70.incompatible.php
either install older version of PHP, or change your code
and maybe this is usefull for you http://php.net/manual/en/mysqlinfo.api.choosing.php
I'm currently trying to connect to a MSSQL database, but from what i've read so far, there are actually extensions and files that i need to download from microsoft itself which i've went and download it here.
https://www.microsoft.com/en-us/download/details.aspx?id=20098
The error that i'm receiving currently receiving is the following.
Fatal error: Uncaught Error: Call to undefined function sqlsrv_connect() in C:\xampp\htdocs\index.php:5 Stack trace: #0 {main} thrown in C:\xampp\htdocs\index.php on line 5
As far as i understand, i know that i'm supposed to append some extensions into the php.ini located in my xampp\php\php.ini file. However, even after appending the file from microsoft, i still can't seem to get connected.
I heard some people mentioned that the php version that i'm using which is currently PHP Version 7.1.1 has some issues connecting back to MSSQL databases but i'm not entirely sure.
Would someone be able to point me to right direction? i've tried looking up and down appending different files into the extension but i still can't seem to do it.
Thank you very much in advance.
edit:
PHP 7 on IIS: Call_user_function could not be located
i've also visited this link, however i'm unsure whether if this is related to the issue I have as i'm on 7.1
I know there are tons of questions about this on SO. But I've been trying to fix this since a month with no luck.
At work we have this very old website that uses an access database, and I cannot do anything about it.I want to work on some changes on my local PC using wamp server. So I donwloaded the website along with the db. Here is how it's supposed to connect :
$conn = new COM('ADODB.Connection');
$db = realpath("dbalerts.mdb");
$conn->Open("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=$db");
But it's giving me this error:
Fatal error: Uncaught exception 'com_exception' with message 'Source: ADODB.Connection
Description:Provider cannot be found. It may not be properly installed.'
in C:\wamp\www\testaccess\index.php:5 Stack trace: #0 C:\wamp\www\testaccess\index.php(5): com->Open('Provider=Micros...') #1 {main} thrown in C:\wamp\www\testaccess\index.php on line 5
It's a test folder whith an index.php where only that code is written. In the same folder is dbalerts.mdb
I tried everything I know. I downloaded AccessDatabaseEngine.exe from MS website which is supposed to have the driver. And it installed properly with no errors( had to uninstall office because it was 64bit)
I am on a win8 machine
Any ideas how I can fix this all while still using COM and ADODB? Because I can't go through changing the connections of every .php file in that website (it's old and poorly designed so not adaptable to changes)
I've got Cassandra working nicely on Debian server however I'm hoping to connect to it from a PHP application.
Currently it seems PDO it the way to go for anything complex as I'm able to use CQL. I'm using the latest forked version of the Apache Cassandra-PDO project.
I'm using the latest Cassandra 2.03 and I can connect to it fine from CQLSH in the terminal.
When I try and connect in PHP using the following code
$db_handle = new PDO("cassandra:host=localhost;port=9160");
I get the following error
Fatal error: Uncaught exception 'PDOException' with message 'CQLSTATE[08006] [8] TTransportException: Transport not open' in /var/www/index.php:9 Stack trace: #0 /var/www/index.php(9): PDO->__construct('cassandra:host=...') #1 {main} thrown in /var/www/index.php on line 9
I've seem a few issues alike on the internet, but no solutions as yet. Hopefully someone can provide some insight into the issue here.
Error 8006 is connection failure. I think you need login and password in PDO Statment like this:
$pdo = new PDO('mysql:host=localhost;dbname=products', 'root', 'root');
Try running 'nodetool status' from the cli to verify the IP address the server is running on.
Then perhaps change localhost to 127.0.0.1 if instead the local host.
