Variable Syntax Question

I have a form that reads in a couple variables via: <input type=textbox name=bob1> <input type=textbox name=bob2> <input type=textbox name=bob3> <input type=textbox name=bob4> Now... I want to read in those variables in something like the following: for($i=1;$i<4;$i++) { echo "$bob$i"; } BUT.... that obviously doesn't work, it simple prints 1, so how to I make it echo the value of the variable bob1? -Hass Get 250 color business cards for FREE! http://businesscards.lycos.com/vp/fastpath/
