PRINT is more recent than ECHO, so it is hardly slower than ECHO. It is much more logical to use the PRINT, but to use ECHO..
You are retarded.
Quoted from the PHP manual:
For a short discussion about the differences between print() and echo(), see this FAQTs Knowledge Base Article: » FAQTs - Knowledge Base - View Entry - What is the difference between echo and print?
If you bother to follow the link, you will see, the first difference is speed. However, since you clearly don't bother to research before making a statement, I will quote and bold the significant part to save you trouble.
Speed. There is a difference between the two, but speed-wise it should be irrelevant which one you use. echo is marginally faster since it doesn't set a return value if you really want to get down to the nitty gritty.
