how to create png image file from the memory ？

Question

I create a png image in the memory ,the code like this

rrdtool_function_graph(605,0,$graph_data_array)

when I run this

print rrdtool_function_graph(605,0,$graph_data_array)

It will show the png image. the question is ,how to convert it to the image file ,like abc.png ,with php?

Just open the file for writing (fopen) then write your data to it (fwrite) and close the file (fclose) — yent, Aug 22 '12 at 11:49

You can use PHP's fwrite to achieve that

$handle = fopen('abc.png', 'w');
fwrite($handle , rrdtool_function_graph(605,0,$graph_data_array));
fclose($handle);
