require file using phar stream does not work within ZendStudio - php

I am struggeling with a quite strange problem within ZendStudio. Including or requiring files inside a phar archive using the phar extensions phar:// stream wrapper will not work from within ZendStudio.
Here is what I have done.
Given the following file structure:
phar/Test.php
pharbuilder.php
usephar.php
With the following content:
phar/Test.php:
class Test {}
pharbuilder.php:
$phar = new Phar(__DIR__ . '/test.phar');
$phar->buildFromDirectory(__DIR__ . '/phar/');
usephar.php:
var_dump(file_exists('phar://' . __DIR__ . '/test.phar/Test.php'));
include('phar://' . __DIR__ . '/test.phar/Test.php');
$test = new Test();
var_dump($test);
Now, if you first run the pharbuilder.php in ZendStudio (ZS 8: right click on file, run as PHP Script) the phar file (test.phar) will be successfully created (before running it, you have to add the ini option phar.readonly=0 to the corresponding php.ini). However, running the usephar.php inside ZS, will result in an error.
bool(true)
Warning: include(): Failed opening 'phar:///somepath/test.phar/Test.php' for inclusion
So obviously, the file can be found, but it cannot be included. I can also access the content of the Test.php within the file using file_get_contents('phar://' . __DIR__ . '/test.phar/Test.php')
Also, I noticed that this will not happen, if I modify the run configuration for this script and disable the checkbox "Display debug information when running". So I assume it has something to do with the ZendDebugger, but I'm not quite sure.
When I run the same scripts from a console, everything works just fine.
I tried this with ZendStudio 8 and 10 and with all in ZS provided php versions (5.4.11, 5.3.21, 5.3.3 all in CGI and CLI).
Since I could not find anybody else with the same problem, I assume that I am doing something wrong and am open to any suggestions. Maybe some secret php.ini directive or something like this.

This issue is now fixed in Zend Studio 10.6.2.
Please mind that as mentioned above you need to modify php.ini file (located in -<studio_home>/plugins/com.zend.php.debug.debugger.win32.x86_\resources\php)
and add
phar.readonly=0

How to get pthreads working in PHP?

I am using wampserver to test & run wordpress code in my local computer. In order to run pthread, I have followed the following steps:
1) I got the pthread zip file from http://windows.php.net/downloads/pecl/releases/pthreads/0.44/
(My machine has php 5.3.13 and downloaded the php_pthreads-0.44-5.3-ts-vc9-x86.zip file from the above link).
2) Extracted the zip file. Moved the php_pthreads.dll to the C:\wamp\bin\php\php5.3.13\ext directory.
3) Moved pthreadVC2.dll to the C:\wamp\bin\php\php5.3.13 directory.
4) Then Opened C:\wamp\bin\php\php5.3.13\php.ini and added the code extension=php_pthreads.dll at the begining of the file.
But when I try to run the following code:
<?php
class My extends Thread {
public function run() {
printf("%s is Thread #%lu\n", __CLASS__, $this->getThreadId());
}
}
$my = new My();
$my->start();
?>
It gives me the following error:
Fatal error: Class 'Thread' not found in C:\wamp\www\wp-admin\includes\post.php on line 2
Can you please tell me how to install pthreads in my computer to use with php? and do I have to install any other software?
I've noticed that wampserver has php.ini in two separate places. One place is in the /wamp/bin/php/php5... directory, and the other place is in the /wamp/bin/apache/apache.../bin directory (where "..." represents version numbers). The two files need to be identical, because apparently both are loaded at different times by the overall wampserver boot-up procedure.
(Note I only discovered this recently, and may be well "behind the curve" of doing fancy things with wampserver --maybe everyone else has been dealing with both files for a long time. So I don't know if this simple thing will fix your problem; I came here looking for info, myself, regarding doing some multi-threading stuff. :)
One other thing. According to this page: www.php.net/manual/en/pthreads.requirements.php
PHP has to be compiled with "--enable-zts" in order for pthreads stuff to work. I have not been able to find any evidence that the PHP part of wampserver was compiled that way.
(months later)
Having decided I didn't really immediately need to do any threading stuff, I went on to do other things, until the need actually arose. I now can say that the version of PHP compiled into WampServer does support the "pthread" extension, although some set-up work is needed, first. The instructions I saw mentioned putting a couple of .dll files (after a download and unZip) into certain places, but that didn't work for me. Copying them to the \Windows\System32 directory did work. (Putting them into the \apache...\bin directory also works; there are some other php .dll files in there.)
After that, much like what you did, it is necessary to define a "class" that extends the "Thread" class, in order to actually do something in another thread. The "run()" function in the Thread class is "abstract", and needs to be "realized" as an actual function in the extended class. Then the "new" operator can create an "instance", an object of that specified class, for actual use. Here's the class that I needed:
//Purpose: Use another thread to run the code in another php file, after a delay
class xT extends Thread
{ var $fil, $tim;
function savWhatWhen($f="", $t=0)
{ $this->fil = $f; //save What, file to process
$this->tim = $t; //save When, delay before processing file
return;
}
function run()
{ ini_set('max_execution_time', 600); //600 seconds = 10 minutes
sleep($this->tim); //do a delay; beware of max-exec-time!
include($this->fil); //load file-to-process, and process it
return;
} }
That "savWhatWhen()" function was created specifically for this extension of the basic Thread class. Here's some code for using that class:
$TH = new xT(); //prepare a separate Thread
$TH->savWhatWhen("d:/wamp/myscripts/test.php", 45);//file-name and delay time
$TH->start(); //after delay, process file
//the code that does this can terminate, while OTHER thread is doing a delay
Note for anyone copying this code, you might need to make sure your "open_basedir" setting in the php.ini allows access to the specified file.
More months later: With lots of things being worked on, I haven't put a lot of time into using my pthread object. I did encounter a peculiarity that makes me wonder about whether or not I can actually use pthreads the way I had hoped. Here is what I have observed:
1. An initial php file is called by AJAX, to do something.
2. The PHP processor on the Web Server does that thing.
3. Various data is supposed to be echoed to the browser.
4. The initial php file calls for the creation of another thread, and terminates.
5. The browser does not yet receive the echoed data!
6. The PHP processor on the Web Server does the work delegated to the second thread.
7. When the second thread terminates, NOW the browser receives the echoed data!
At this writing I'm thinking I missed something. Perhaps I need to do some forceful "flush" stuff when the first thread ends, so that the browser can receive the echoed data and the user can do things while the PHP processor on the server is also doing things.
Check for extension_dir = "ext" in you php.ini file. Make sure it points to the folder where your extensions reside and make sure it's not commented (it has a semicolon ; in front of it)
You have to add a require_once() with the path of the Thread class before extending it (if your framework don't use an autoload class system)
I've encountered the same problem, in my case placing the pthreadVC2.dll in
..wamp\bin\apache\Apache2.4.4\bin
(instead of ..\wamp\bin\php\php5.4.16 as the guide in php.net instructs) solved the problem
Wamp server has a separate php.ini config file for the browser and for the cli.
To use the pthreads module in the browser with WAMP Server you need to copy the "pthreadVC2.dll" into the apache "bin" directory also.
You should now have he "pthreadVC2.dll" in both of these folders (if installed in default location):
C:\wamp\bin\php\php[x.x.xx]\bin
C:\wamp\bin\apache\apache[x.x.x]\bin
You will also need to update the php.ini file within the php bin directory AND the apache bin directory to include:
extension=php_pthreads.dll
This now means you can use pthreads in the browser and in the cli with wamp server
After encountering the same problem, I noticed that I have installed the wrong Pthread version (3.1.6 : requires PHP7+) which wasn't compatible with my PHP version (5.5.12). Solved the problem with Pthread version 0.0.44. An earlier version should probably work well.
Here is the download page for Pthread and the installation page. Be careful about the both php.ini location as mentioned above (Apache folder=for Browser, PHP folder=CLI).

passing parameters to a bat (or vbs) in php

Objective: Use PHP to call a vbs that converts an xls/xlsx file to a csv.
Question: How can I pass a source file path and a destination file path to a vbs that converts xls/xlsx to csv and run that vbs in a PHP web application?
Details: I have a working vbs that takes a source file path and a destination file path and converts the xls/xlsx at source file path into a csv. I can execute it from the Windows cmd line and it does exactly what I want it to do. I can also put the execution command into a bat file and run the bat file to achieve the same results. However, when I use exec()/shell_exec()/system() in PHP to execute the same command no csv is created. (If I try to run the bat from PHP using system() the contents of the bat file show up on the page, in fact, echo Conversion complete! prints "echo Conversion complete! Conversion complete.") I haven't seen any errors yet.
Note: I know about PHPExcel, I'd prefer not to use it.
excelToCsv.vbs
On Error Resume Next
if WScript.Arguments.Count < 2 Then WScript.Echo "Please specify the source and the destination files. Usage: ExcelToCsv <xls/xlsx source file> <csv destination file>"
Wscript.Quit
End If
csv_format = 6
Set objFSO = CreateObject("Scripting.FileSystemObject")
src_file = objFSO.GetAbsolutePathName(Wscript.Arguments.Item(0))
dest_file = objFSO.GetAbsolutePathName(WScript.Arguments.Item(1))
Dim oExcel
Set oExcel = CreateObject("Excel.Application")
Dim oBook
Set oBook = oExcel.Workbooks.Open(src_file)
oBook.SaveAs dest_file, csv_format
oBook.Close False
oExcel.Quit
batConverter.bat
excelToCsv.vbs conversionTestSourceMS2003.xls batTest.csv
echo Conversion Complete!
index.phtml
<?php
system("cmd /c batConvert.bat")
?>
Note: All of the above files (along with conversionTestSourceMS2003.xls) are in the same directory. I have not implemented any way to pass the parameters (since I can't get it to work even if it's all hard coded...)
Set Up: PHP5, Zend Framework, WAMP, Windows 7 (localhost).
For the sake of simplicity, I merged everything into a single ASP page. This will allow me to hopefully see a similar problem in IIS, and since it is in a single ASP script, I will be able to see the error more directly. My test machine is running on Windows Vista SP2 on IIS7 with Excel 2007 SP3.
excelToCsv.asp
<%
Option Explicit
Dim csv_format, src_file, dest_file, strPath, objFSO
csv_format = 6
src_file = "conversionTestSourceMS2003.xls"
dest_file = "testbat.csv"
strPath = "[HARDCODED PATH HERE]\"
src_file = strPath & src_file
dest_file = strPath & dest_file
Dim objExcel, objBook
Set objExcel = CreateObject("Excel.Application")
Set objBook = objExcel.Workbooks.Open(src_file)
objBook.SaveAs dest_file, csv_format
objBook.Close False
Response.Write "Conversion Complete!"
objExcel.Quit
%>
When running this code, I got a generic ASP error. So, I enabled detailed error messages in ASP and I get this following error...
Microsoft Office Excel error '800a03ec'
Microsoft Office Excel cannot access the file '[HARDCODED PATH
HERE]\conversionTestSourceMS2003.xls'. There are several possible
reasons: • The file name or path does not exist. • The file is being
used by another program. • The workbook you are trying to save has the
same name as a currently open workbook.
/temp/ExcelToCsv.asp, line 18
Now, this is not Apache, but I do believe the problem is related to yours. This error implies there is a security/permission problem where Excel cannot do what it needs to do to access or read the file. In fact, I encountered similar errors when I was executing the VBScript (and passing the error up the chain) from PHP (in IIS).
I believe it can be resolved by changing the Windows User being used to create the process. This can be configured in Services.msc by editing the Apache service and changing the Log On tab to an actual Windows user instead of a Service Account. I have not tested it yet, though, since setting up Apache is not something I can do right now.

How to configure wampserver for spatialite

I am in windows 7. I installed WAMPServer. Now, I can not load spatialite libraries. It is showing warning..
Warning: SQLite3::loadExtension() [sqlite3.loadextension]: Not
supported in multithreaded Web servers
Here is my total configuration procedure, what I have done...
From this link I got spatialite lib. I copied "libspatialite-1.dll" and paste it to "D:\wamp\bin\php\php5.3.8\ext" which contains php extention dlls.
http://www.gaia-gis.it/spatialite-2.3.1/libspatialite-win-x86-2.3.1.zip
Then I edited php.ini file. I changed the following configuration.
.
sqlite3.extension_dir = C:\libspatialite-win-x86-2.3.1\bin
.
extension=libspatialite-1.dll
.
enable_dl = On
And lastly, I copy and paste all the libraries from my downloaded libspatialite-win-x86-2.3.1 to my project folder(libspatialite.a, libspatialite.dll.a, libspatialite.la) in my php code i write the script as follows...
<?php
$db = new SQLite3('sixcommunes.sqlite');
$db->loadExtension('libspatialite.a');
$rs = $db->query('SELECT spatialite_version()');
while($row = $rs->fetchArray()){
print "<h3>SQLite version: $row[0]</h3>";
}
?>
I do not know what I have done wrong or how to solve this problem?
Haven't seen any answer, so giving my own. I have used spatialite in C#, I think for using Spatialite Extensions you don't have to load libspatialite like a usual PHP extension, instead something similar to this should be done. (this is c# code, just trying to give you an idea)
SQLiteCommand sqliteCommand = new SQLiteCommand(String.Format("SELECT
load_extension('{0}');", "libspatialite-2.dll"), connection);
sqliteCommand.ExecuteNonQuery();
You have to execute Select load_extension("libspatialite-2.dll") on sqlite to use Spatialite.
Hope this helps

Temporarily disable cURL for testing purposes

I am writing a class that detects whether cURL is available, does one thing if it is, and another if it isn't. I therefore need to know how to disable cURL temporarily to test this class. I do not want to change the PHP INI file. Any ideas much appreciated.
Just wondering, Im writing an alternative for if cURL is unavailble, how likely is this? Am I wasting my time. Is cURL usually available?
Curl is enabled / disabled in your php.ini. You can't enable and disable it any other way.
Open php.ini find the below and put a semi colon before it to comment it out:
extension=php_curl.dll
AFAIK there is no way to do this at run time, because modules are loaded during PHP startup, before any of you code is executed. The only way to do it is by disabling (or rather, not enabling) an extension in php.ini. You probably can't even do that with cURL, as it will probably be compiled in, not dynamically loaded.
Having said that - why not just change the check to test your "if not available" code - presumably you have a block something like this:
if (curl_exists()) { //obviously there is no such function, but you must have some condition that determines this
// Do stuff using curl
} else {
// Do something horrible
}
well, just change it to this temporarily:
if (!curl_exists()) {
// etc etc
I think the best option is to change your detection script to allow disabling it with a manual configuration.
You cannot disable function on the fly. You need to change php.ini for that.
http://www.php.net/manual/en/function.dl.php
dl — Loads a PHP extension at runtime
bool dl ( string $library )
Loads the PHP extension given by the parameter library.
Use extension_loaded() to test whether a given extension is already available or not. This works on both built-in extensions and dynamically loaded ones (either through php.ini or dl()).
Warning:
This function has been removed from some SAPI's in PHP 5.3.
<?php
// Example loading an extension based on OS
if (!extension_loaded('sqlite')) {
if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
dl('php_sqlite.dll');
} else {
dl('sqlite.so');
}
}
//this deals with sqlite but would be easy to figure out how to use it for cURL :)
?>
So you can comment out the loading of cURL extension in php.ini and then "dynamically load" it when needed.
HTH
probably the easiest way is by open file curl.ini, Im use ubuntu 12.04 and file located at
/etc/php5/apache2/conf.d/curl.ini
leave a comment by adding semicolon before extension=curl.so
You can see the location of curl.ini through phpinfo ();
dont forget to restart the Apache
sudo service apache2 restart
Curl is available as long its extension is loaded (which is mostly by default).
You can check what curl extension provides by the following command:
php --re curl
which gives you list of functions, classes and its methods.
To temporary disable curl extension, you can run PHP with -n to simply ignore your php.ini, for example:
$ php -n -r "print_r(curl_version());"
Fatal error: Call to undefined function curl_version() in Command line code on line 1
Here is working example:
$ php -r "print_r(curl_version());"
Array
(
[version_number] => 463623

Temp-Files in Symfony-Cache folder

I'm using Windows on some production machines (IIS with FastCGI-PHP). Since the update of one SF-Project to 1.3.x I notice some strange problems. The Server is "collecting" Temp-Files in the config-cache folder of the applications. They are named like con1718.tmp and always containing the autoload-config-cache. The tmp-files are not generated for every request but I have 1 or 2 new files every half an hour or so. If the application is running some days/months there are a lot of these Temp-Files (Megabytes of them).
Machine-Details: - Windows Server 2008 - IIS 7 - ZendServer? with PHP 5.2.11
Project with SF 1.3.3
Any ideas what the problem can be?
I checked out symfony 1.4 and saw this in the code:
// Hack from Agavi (http://trac.agavi.org/changeset/3979)
// With php < 5.2.6 on win32, renaming to an already existing file doesn't work, but copy does,
// so we simply assume that when rename() fails that we are on win32 and try to use copy()
if (!#rename($tmpFile, $cache))
{
if (copy($tmpFile, $cache))
{
unlink($tmpFile);
}
}
This piece of code should be in sfConfigCache.php on line 354, could you check you have this lines? If not, consider updating, or patching, and if yes, you could log $tmpFile before unlinking it, just to see if there is an attempt to unlink these files or not.
To add more information log, you should try this code instead:
if (!#rename($tmpFile, $cache))
{
sfContext::getInstance()->getLogger()->info('attempt to renaming ' . $tmpFile . ' failed, trying copy');
if (copy($tmpFile, $cache))
{
sfContext::getInstance()->getLogger()->info('copy successful, now unlinking ' . $tmpFile);
unlink($tmpFile);
}
else
{
sfContext::getInstance()->getLogger()->err('probem with copy for file '.$tmpFile);
}
}
'con1718.tmp' looks like a temporary file name generated with tempnam PHP function:
tempnam('c:/tmp', 'con'); // produces something like c:\\tmp\con1234.tmp
I used grep on symfony sources to find such calls but didn't find any tempnam() usage with 'con'. Maybe it's one of the plugins you're using?
Any chance you're running the Windows Cache Extension for PHP (Windows Cache Extension 1.1 for PHP 5.2 in Web Platform Installer 2.0)? I've noticed that while this package tries to ape the behaviour of APC PHP Accelerator that is widely used, it does consume a lot of resources and do some odd things, especially file writes in odd places. I've yet to mash symfony and it together, but will be doing so in the next few weeks. Otherwise, my specs match yours quite closely.
Not a full answer maybe, but if it is installed, how about disabling it and retrying?
