[PHP-DEV] Graphs and Charts

[Guilherme A. Mendes]

Hi all,

It may does not make sense, but I'm writing a web based script in C++
and now I need to build 3D pie/bar charts. The best solution and quality
I have found was JpGraph that uses PHP Gd Library / Functions.

I was thinking about using the PHP source code in my C++ program to
generate the charts insted of using the main GD code from Boutell -
because the two versions are different, Boutell's GD doesnt have native
functions to build 3D images.

Is it possible to use the PHP Header in my C++ program to use the
features of GD that exits into PHP ?

Thanks in advance and sorry if it does not make sense.

Regards.
MENDES, Guilherme

You should have a look at the gdchart library. There is a PHP extension
for it in pecl.

Hi !

I had the same problem, and i solve it by the use of the 'embed' sapi for PHP.

Just link you application with it and you will be able to call (not tested
but should be near ok):

int run_php_script( const char *script_file ) {
zend_file_handle file_handle;;
int argc= 1
char * argv[]= { "php_embed" };
int ret;

file_handle.filename = estrdup(script_file);
file_handle.type = ZEND_HANDLE_FILENAME;
file_handle.opened_path = NULL;
file_handle.free_filename = 0;

PHP_EMBED_START_BLOCK( argc, argv );
ret= php_execute_script( file_handle TSRMLS_CC);
PHP_EMBED_END_BLOCK();

return ret;
}

and then call anywhere in your code:
run_php_script( "myJpGraphCode.php" );

Just a problem: all outputs are on stdout !
But you can buffer the outputs in the php script and write them to a file.

I hope this will be helpful !

Eric
