I have .cpp file:
#include<stdio.h>
void main()
{
printf("Karim");
}
I created .so file using this command:
g++ -I ./inc -fpic -c test.cpp -o LinC.o
g++ -shared -o LinC.so LinC.o
I want to make function call main() from php file. So how could I do t
I can use zend engine, but I dont want to use it. Any other way to do this?

I am trying to generate a PHP extension of a C++ program (Simstring), but I am a little stucked.
The program already propose a python and a ruby extensions working with Swig.
I followed the Swig PHP documentation but I got an error.
Here is what I have done and the result I got, maybe you can help me with that:
cd swig;
mkdir php;
ln -s ../export.cpp
ln -s ../export.h
ln -s ../export.i
swig -c++ -php -o export_wrap.cpp export.i
g++ `php-config --includes` -fPIC -c export_wrap.cpp
g++ -shared export_wrap.o -o simstring.so
sudo mv simstring.so my-php-extension-dir/
I load the extension in my php.ini but I got the following error :
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20121212/simstring.so' - /usr/lib/php5/20121212/simstring.so: undefined symbol: _ZN6writer5closeEv in Unknown on line 0
Thanks a lot
Thanks to #zaufi, I searched more and found the answer.
I was definitively missing a file.
The right commands are the followings (please note the export_wrap.cpp AND export.cpp resp. export.o AND export_wrap.o)
g++ `php-config --includes` -fPIC -c export_wrap.cpp export.cpp
g++ -shared export.o export_wrap.o -o simstring.so
For more informations, you have to "include" the simstring.php generated file.
I want to compile extension for PHP under Windows and I need to run such command:
g++ `php-config --includes` -fPIC -c some_script.cpp
but when I run this command I received an error:
g++: error: `php-config: No such file or directory
g++: error: unrecognized option '--includes`'
where can I get php-config shell script without recompiling PHP (under Windows)
The problem is not that you don't have the script, it's that the Windows shell doesn't know what you're trying to do because it doesn't support backticks. The command wants to run the php-config script and include the output in the command, but instead g++ is being passed \php-configas the first argument, and--includes`` as the second argument, which are not valid arguments to GCC.
You can't run a UNIX shell command in Windows. Either use a UNIX-style shell (e.g. via Cygwin or Mingw32) or just use a different command, e.g. figure out what the necessary include flags are and use them:
g++ -I/some/path -fPIC -c some_script.cpp
i am new to setting php servers, and i had go though other related post, seems like nobody have the same error as i have.
I am using MAMP 2.0.2, and running PHP 5.3.6,
and I was trying to install oAuth on my local MAMP, using following commands:
$ cd /Applications/MAMP/bin/php/php5.3.6/bin
$ ./pecl install oauth
however, it return such error:
Notice: unserialize(): Error at offset 276 of 1133 bytes in Config.php on line 1050
ERROR: The default config file is not a valid config file or is corrupted.
What is happening? PECL is bundled in MAMP, which should be working out of the box....
Update:
I read a post elsewhere suggest that the config file's data, which holds the install paths are in-correct, so i changed some value in the following file :
/Applications/MAMP/bin/php/php5.3.6/conf/pear.conf
Then, i use the command:
$ ./pecl install oauth
Which it starts download and unpack, but when it try to install, it gives:

I know this is old but I found this question while having a similar issue.
MAMP doesn’t ship with a bunch of the PHP sources
Download MAMP components and configure
URL: http://www.mamp.info/en/downloads/index.html (i.e. MAMP_components_2.0.2.zip)
Unpack your MAMP_components_2.0.2.zip
Identify your php-5.x.x.tar.gz file (where 5.x.x is your version of PHP)
If you are using php > 5.4.10 then download the sources from http://php.net/releases as they are not in the MAMP components download (credit pulkitsinghal in comments)
Create directory for your PHP sources:
mkdir -vp /Applications/MAMP/bin/php5/include
Untar php-5.x.x.tar.gz into /Applications/MAMP/bin/php/php5.*/include or /Applications/MAMP/bin/php5/ include:
tar zxvf php-5.x.x.tar.gz -C /Applications/MAMP/bin/php/php5.?.??/include
Rename your php-5.x.x directory to php (without the version numbering):
mv /Applications/MAMP/bin/php/php5.2.17/include/php-5.?.?? /Applications/
MAMP/bin/php/php5.2.17/include/php
Configure PHP sources (it’ll create necessary files i.e. zend_config.h, tsrm_config.h, etc.):
cd /Applications/MAMP/bin/php/php5.?.??/include/php
./configure
The process was for another fix but this resolved the issues with php.h not being found
Credit to where I found the answers - :

Google Doc detailing process
I had the same problem whilst trying to pecl install -f ssh2 with MAMP.
Here's how I fixed it:
MAMP doesn't provide the source code archive for PHP 5.4.10 so download it from php.net
Extract the source code archive to /Applications/MAMP/bin/php/php5.4.10/include/php
Run ./configure to configure the source code for your platform (without this step the pecl install will fail looking for a bunch of header files)
Retry your pecl install
(much thanks to Stephen's answer which is pretty much the same)
This is a complement to Stephen's answer and Greg's comment
When compiling xdebug 2.3.2 for php 5.6.2 on OSX 10.10.2, I could not get rid of the
'zend_config.h' file not found
error until I added the following option to ./configure in the php folder:
./configure --without-iconv

PECL Modules are compiled modules, in order to install them, you need the PHP headers. You can found the headers on php.net/downloads.php make sure you download a version which match with your PHP version. Then you can follow this : Installing PHP OAuth in MAMP environment
swig -php example.i
This will produce 3 files example_wrap.c, php_example.h and example.php. The first file, example_wrap.c contains all of the C code needed to build a PHP extension. The second file, php_example.h contains the header information needed if you wish to statically link the extension into the php interpreter. The third file, example.php can be included by PHP scripts.
ya the three files are created, then execute the following coding.
this is used for create the example.so file.
gcc `php-config --includes` -fpic -c example_wrap.c
gcc -shared example_wrap.o -o example.so
but so many errors will displayed,
help me..
I think you're missing a step along the way, example.i should accompany example.[hc] so your compilation should go something like:
gcc -c example.c -o example.o
gcc `php-config --includes` -fpic -c example_wrap.c
gcc -shared example_wrap.o example.o -o example.so
I have been trying to compile geos on my restrcited(no root) environment and I am having some difficulties...
I did the following
wget http://download.osgeo.org/geos/geos-3.4.2.tar.bz2
tar jxf geos-3.4.2.tar.bz2
cd geos-3.4.2
nano ~/.bash_profile
# I added PATH=$PATH:$HOME/local/bin export PATH
./configure --enable-php --prefix=$HOME/local/ && make clean && make
And Im getting the following errors

According to some github, this happens with MAMP too
This happens because GEOS requires PHP header files from the original PHP source, and MAMP does not include those.
EDIT 1:
I have also added this in ~/local/share/config.site
CPPFLAGS=-I./opt/alt/php53/usr/include/
LDFLAGS=-L$HOME/local/lib
php.h is located here: ./opt/alt/php53/usr/include/php/main/php.h
info.h: ./opt/alt/php53/usr/include/php/ext/standard/info.h
zend_exceptions.h: ./opt/alt/php53/usr/include/php/Zend/zend_exceptions.h
EDIT 2:
Last thing: my ./configure tells me this
checking for php-config... /usr/local/bin/php-config
checking for php... /usr/local/bin/php
So my question, if Im on the right track for solving this, is how do I include my php header files while compiling geos in a non root evnironment in centOs ?
Im quite lost to be honest !
I'm fairly certain the path to your PHP installation does not start with a . - not from inside the geos-3.4.2 folder anyway, and certainly not from inside an arbitrary source folder.
You should make that path absolute.
I'm assuming the opt folder is in your user folder, so the full path would be $HOME/opt/alt/php53/usr/. Thanks for the clarification, the full path should then be /opt/alt/php53/usr/.
You need to add the bin folder to your PATH variable, the include folder to CPPFLAGS and the lib folder to LDFLAGS.
With $HOME/local/ this is not necessary, since that is the PREFIX, and will be added automatically.
Also note that when adding stuff to your PATH variable, you should add it to the beginning instead of the end, so that it will take precedence over system binaries.
I also suggest you undo the changes you made to ~/local/share/config.site (or remove the file, if it didn't exist), as options there will affect all automake-based projects.
You should rather pass CPPFLAGS and LDFLAGS as arguments to configure.
After all that, your command block should look something like:
wget http://download.osgeo.org/geos/geos-3.4.2.tar.bz2
tar jxf geos-3.4.2.tar.bz2
cd geos-3.4.2
export PATH="/opt/alt/php53/usr/bin:$PATH"
./configure --enable-php --prefix="$HOME/local" CPPFLAGS="-I/opt/alt/php53/usr/include" LDFLAGS="/opt/alt/php53/usr/lib" && make clean && make
