Difference between revisions of "Elphel PHP constants"

Revision as of 09:22, 22 December 2008

You may view all the currently defined constants using the following PHP operator:

print_r (get_defined_constants());

To use constants in PHP programs you may just type in the name (as in the following example):

echo elphel_get_P_value(ELPHEL_SENSOR); // No "$" in front of the constant name!

or dynamically compose the constant name as in

$elphel_prefix="ELPHEL_"
echo elphel_get_P_value(constant($elphel_prefix . "GAMMA"));
