[PHP] is_null question

2002-07-12 Thread Matthew K. Gold
Hi Everyone, Here's my problem: I'd like to make the printing of some text dependent on whether or not a variable is null. In the following example, when $row[1] is null, what gets printed on the page is Email: . I'd like the script to not print Email: if row[1] is null. It looks like I
