asterisk users - Sep 2009 - passing commands asterisk cli and getting output using PHP AGI

Hellos,

I know this might be an easy one but either way I am stuck...I need to
execute asterisk cli commands using php agi and get the output via the same
script.

How to I execute let's say "show hints" and get the output back to
the
script? I have tried

$agi->exec("show hints");

but I am getting the output below on the cli debug

AGI Rx << EXEC show hints
AGI Tx >> 200 result=-2
AGI Rx << VERBOSE "EXEC show hints  returned -2" 1
AGI Tx >> 200 result=1

Use asterisk manager within the script.

$asm->command("show hints");
