Variable variables techniques do not work when one of the
"variables" is a constant. The example below illustrates
this. This is probably the desired behavior for constants,
but was confusing for me when I was trying to figure it out.
The alternative I used was to add the variables I needed to
the $GLOBALS array instead of defining them as constants.
<?php
define("DB_X_NAME","database1");
define("DB_Y_NAME","database2");
$DB_Z_NAME="database3";
function connectTo($databaseName){
global $DB_Z_NAME;
$fullDatabaseName="DB_".$databaseName."_NAME";
return """.${$fullDatabaseName}.""";
}
print "DB_X_NAME is ".connectTo("X")."
";
print "DB_Y_NAME is ".connectTo("Y")."
";
print "DB_Z_NAME is ".connectTo("Z")."
";
?>
