[cairo] Problem with PHP extension writing (under use of Cairo)

["tschobber tschöbbi"]

Hi,

I'm having trouble with PHP extension writing (with C++ under Linux) when using Cairo functions: I use this link as a tutorial for extension writing http://devzone.zend.com/node/view/id/1021. the problem is that all is working fine when i call functions with no cairo code in it, but when I call the function below php just aks me if I want to save the .php file on disk. Maybe it is because i just copied the headerfiles into the source folder under the php sourcetree because before the source file didn't compile because of missing the header files of cairo. 

Source a PHP function using cairo:

PHP_FUNCTION(paint_with_cairo)
{
    long shape = 0;



	if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "l", &shape) == FAILURE) {

		RETURN_NULL();

	}


	cairo_t *cr;

	cairo_surface_t *surface;

	int x, y, count_rows,i;

	int width, height = 100;

	//surface = (cairo_surface_t *) cairo_svg_surface_create("Cairo_example.png", 1000.0, 1000.0);

	surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32,2000,2000);



	//surface = (cairo_surface_t *) ("Cairo_example.svg", 2000.0, 2000.0);

	cr = cairo_create(surface);



	y = 1;

	count_rows = 0;

		for (i = 0; i < (numShapes); i++){



			if(count_rows > 10){

					y++;

					x = 0;

					count_rows = 0;

				}



			if(shape == 0){

				cairo_rectangle(cr, x * 90, y * 70, 80, 55);



			}else if(shape == 1){

				

				

				 cairo_set_source_rgb(cr, 0.4, 0.5, 0.5);

				 cairo_arc(cr, x*120+60, y*120+60, 60, 0, 2*M_PI);

				 cairo_stroke_preserve(cr);

				 cairo_set_source_rgb(cr, 0.5, 0.2, 0.1);

				 cairo_fill(cr);





			}else{

				 cairo_move_to(cr, 80*x, 80*y);

				cairo_set_source_rgb(cr, 0.4, 0.5, 0.5);

				cairo_line_to(cr, 80*x, (80*y)+75);

				cairo_line_to(cr, (80*x)+75, (80*y));

				cairo_line_to(cr, 80*x, 80*y);

				cairo_close_path(cr);



			}

			x++;

			count_rows++;

	}



	cairo_fill(cr);



	//cairo_set_source_rgb(cr, 0, 0, 0);



	cairo_surface_write_to_png(surface,"/opt/lampp/lampp/htdocs/bla/c_example.png");



	cairo_destroy(cr);



	cairo_surface_destroy(surface);
}



i hope you can help me solving the problem. 

regards,
martin
