Changed usage for popen on php4-1.1?

[Anon]

Hi,

Does anyone know why the following bit of code refuses to work on php4-1.1?

$text = "hello";
$fpop=popen("vi testfile.txt","w");
fputs($fpop,"i");
fputs($fpop,"$text");
fputs($fpop,chr(27));
fputs($fpop,":wq\r");
pclose($fpop);

Works great on 4.06!

Any pointers would be appreciated. (no pun intended 😉

Thanks,
