Bug description: Support for negative_equals_false configuration variable
Hi,
I'd like to see support for a configuration variable which enables developers, to set a
negative value (ie - a negative numeric value, not a string starting with a - sign or an
intval("-5abc")) to resolve to FALSE.
This would make error_handling using constants so much easier. Example:
<?
define(FILE_NOT_IN_INC=-1);
define(INVALID_FILE_REQUEST=-2);
$errors=array(
'unknown error',
'Invalid installation. Please contact your administrator. File not in designated include
dir',
'Invalid installation. Please contact your administrator. Filename is invalid');
class definition {
...
function do_includes()
{
//______Centralize security checks in the main configuration object
$functions_file=$this->appname.'.functions.php';
if(file_exists($this->inc_dir.'/'.$functions_file))
{
if(!ereg("^(\.|/)", $functions_file))
{
//___assume $this->inc_dir is in php_include_path, but eliminate security threat,
that '.' is prefered over $this->inc_dir.
include $functions_file;
}
else
{
return INVALID_FILE_REQUEST;
}
}
else
{
return FILE_NOT_IN_INC;
}
}
}
$instance=new definition;
$ok=$instance->do_includes();
if(!$ok)
{
mail($instance->admin, "Installation problem your_app", "$SCRIPT_NAME -
__LINE__ - $ok");
die($errors[abs($ok)];
}
?>
