Hi pecl-dev, I'm reading about PHP extention, but I don't know how to call C function from PHP. I mean, If I have the hello.h file with code following: //hello.h #define a 1; void sayhello(); int getNumber(int); //end hello.h And the file hello.c with code following: //hello.c void sayhello() { printf("Hello world"); } int getNumber(int i) { int res=i+a; return res; } //end hello.c Could you help me to call the functions in hello.h file from PHP program? Can I do it? Thank you for your help. yours sincerely! Tri, Tran Huu _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com
