[PHP] Load a C library into extension?
Hi all, I have no doubt posted many queries here in the past few days, and am thankful for all the help I have received. :) I have been able to write a helloworld extension and compile it. The next step is to call a function in a library libfoo.so. I think this needs a modification in config.m4. Any ideas how to go about it? I have already tried editing LIBNAME and LIBSYMBOL. It says: checking for foo in -lfoo... no configure: error: wrong foo lib version or lib not found The file is present as ext/myext/lib/libfoo.so.

[PHP] zend_parse_parameters seg faults on string input.
Hi all, In the PHP file, I have written: helloworld(hello, world) where helloworld is in an extension. Now, I use zend_parse_parameters() to parse input as follows: char* hstr = NULL, *wstr = NULL; argc = ZEND_NUM_ARGS(); if (zend_parse_parameters(argc TSRMLS_CC, ss, hstr, wstr) == FAILURE) return; I get a seg-fault when I run the PHP file. However, it works for one argument. Am I missing something? Thanks, Deepak -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you compiled the extension into PHP this shouldn't be necessary. In fact, unless you build an extension to be a DSO you shouldn't be able to use dl() with that extension anyways! This is actually my first venture to PHP extensions. I am trying to write a simple C function, which prints 'hello world', as a PHP extension.
