int(11) vs. int(anything else)

Question

I\'m new to web programming and doing different tutorials that I can find on the net.

I did my research and found out that in int(11), 11 is the maximum display widt

Answer 1

Yes it specifies the display width, and this comes into play only when ZEROFILL is specified. So at that time it can pad the field value with the required number of zeros.
