l95theses Posted July 11, 2007 Share Posted July 11, 2007 I'm trying to make this code dynamic so that I can decrease it by the number of items in the inventory, this is the static formula to that works, but I don't want to have to add this every time I have another item to check for. Help me to dynamically subtract one from the amount of items. PLEASE!!! thanks... if ( $$itemg == $citem1_array[0] ) { echo "$citem1_array[1] - $citem1_array[2]"; echo "<br>"; } if ( $$itemg == $citem2_array[0] ) { echo "$citem2_array[1] - $citem2_array[2]"; echo "<br>"; } if ( $$itemg == $citem3_array[0] ) { echo "$citem3_array[1] - $citem3_array[2]"; echo "<br>"; } Quote Link to comment Share on other sites More sharing options...
teng84 Posted July 11, 2007 Share Posted July 11, 2007 i dont understand but may be this for ($x=0;$x<=count(fut here the array); $x++) { //now put the x on the counter $array[$x]; and if you want the $xto be 1 or 2 just $array[$x+1]; } i dont know maybe is that what you mean Quote Link to comment Share on other sites More sharing options...
