Will different (older) versions of PHP affect my code. If I have a mail form that works on server A running PHP4 should it work on server B with an older version of PHP??
this is too general of a question
but i wouldnt count on too many recently written scripts coded for php4 or 5 to work on php3
if they are very simple chances are they will work, but it really depends on the way it was coded.
