php-extension

问题 To you gurus out there, is there any hidden gem in PHP that could unload a specific extension at runtime ? 回答1: No, that's not possible and most likely never will: [2011-02-08 11:34 UTC] rasmus@php.net extension unloading on a per-request basis simply isn't feasible from a performance point of view. And you obviously can't unload and leave it unloaded for the next request because that next request may be for a page that expects the extension to be there. However, using dl() is discouraged

问题 I installed PHP 7 to my server (as a result, I have not /etc/php5 and /etc/php/7.0). When I run my web app, I cant see any of my previous CURL (or fork). at first I got this err msg: Message: Call to undefined function curl_init() and after installing php7-curl i get it enabled - approved on info() function and this test code: var_dump(_isCurl()); function _isCurl(){ return function_exists('curl_version'); } returning TRUE. but when having an actual CURL in my code I get this error: PHP

问题 In PHP 5.3 is there a way to rename a function or "hook" a function. There is the rename_function() within "APD" which has been broken since ~2004. If you try and build it on PHP 5.3 you'll get this error: 'struct _zend_compiler_globals' has no member named 'extended_info' This is a really easy error to fix, just change this line: GC(extended_info) = 1; to CG(compiler_options) |= ZEND_COMPILE_EXTENDED_INFO; I modified my php.ini and the APD shows up in my phpinfo() as it should. However when

问题 I'm thinking of writing a PHP extension module but can't tolerate the idea of messing with C or, for that matter, C++. I know that some languages provide compatibility with C APIs, Pascal being one of them, sorry for mentioning it. And I quite suppose that, since the days of Wirth, a further number of languages have appeared that ditch the memory juggling but keep being compiled to native binaries and provide interoperability with all the other programs and libraries out there. Only I didn't

问题 I am using PHPExcel PHP library for reading xlsx files and every thing is fine. when I am deploying my web application in our server I am facing the below error: Fatal error: Uncaught exception 'Exception' with message 'ZipArchive library is not enabled' I know that ZipArchive is a requirement for PHP Excel. and I need to follow the install instructions for it to enable it on my production server. This error because PHPExcel require the below requirements: PHP version 5.2.0 or higher PHP

问题 So this is the case, I am trying to develop an php-extension for my customers. I use SWIG for generating the wrapper code and my main code is c++. After I create my extension successfully I load it in /ext and restart the web server for testing it. I've got the error which mentioned that the extension has been built with API 20090626 but the PHP server(in my case XAMPP) API is 20100525. I totally understand the error, so I open the Zend_modules.h header file in php source and change the API

问题 I'm writing a PHP extension that takes a reference to a value and alters it. Example PHP: $someVal = "input value"; TestPassRef($someVal); // value now changed What's the right approach? 回答1: Edit 2011-09-13 : The correct way to do this is to use the ZEND_BEGIN_ARG_INFO() family of macros - see Extending and Embedding PHP chapter 6 (Sara Golemon, Developer's Library). This example function takes one string argument by value (due to the ZEND_ARG_PASS_INFO(0) call) and all others after that by

问题 I installed nginx, php, php-fpm, php-pecl-redis by yum. All of them work but the last one. When I run /usr/sbin/php-fpm , I got this: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/redis.so' - /usr/lib/php/modules/redis.so: undefined symbol: igbinary_unserialize in Unknown on line 0 I don't know what "igbnary_unserialize" means and how to fix it.
