Re: [PHP] Clearing a variable

2001-01-18 Thread jeremy brand 

you can clear a string by doing this:

$string = '';

you can clear an array by doing this:

$array = array();

you can clear (or zero out rather) an integer or float by doing:

$int_or_float = 0;

or you can simply unset() the variable:

unset($any_of_the_above);

Actually, just to clarify, that removes a variable from the symbol table.
to clear the contents of a variable, just set it to null:

$var = NULL;

// $var is now empty
