How to achieve more ?? Material synchronization

How many calls ?? Material, and then in the same ???? "One by one" and "points? E. is it different? Why? R 」?? Y material ?? Pdateorinsert. Every question ?? The update, insert ??? K is different! & Nbsp ;? Why? Which of the following statements about _ loop + SyntaxHighlighter. al ?? Material, and then in the same ???? "One by one" and "points? E. is it different? Why? R 」?? Y material? Update or insert. Every question ?? The update, insert ??? K is different! ======================================
? Why? In _____ loop + array

1 .? Y material? Yi harmonic salmon Y material:
Db_query? The same row looping? R, phase ?? Too many tasks? Pdate? Material communication? Input array.
According to the needs of each person ,? Some? Can text, checkbox, or hidden be used? Type? B is ?.? However, is checkbox the most common? Type.

Root ?? What about ount? Result? OK? Spin, put db_update? Go ,? Loop to complete all? Material update and storage? I.
? For example:
========================================================== ==========
#### 1. update. php (as the mainstream development language): Retrieve it using loop + array? To update ........


# In question ?? Call? Expected ?? Nbsp;
$ Query = "select * from $ userstable where ...................

#? In the loop, retrieve them one by one? Raw materials
$ I = 0;
While ($ I <$ num ):
...............
$ Id = MySQL (the best combination with PHP) _ result ($ result, $ I, "id ");
..................
............................
# Take ?? Is the type of required? Updated? Too many ?? To array ..........
Echo"Echo" ";
Echo" ";

$ I ++;
Endwhile;


========================================================== ====================
#### 2. activate. php (as the mainstream development language ):? After the material is updated, what is transparent? Loop + array to save ...................

.......
For ($ I = 0; $ I <count ($ Cname); $ I ++ ){
$ Name = $ Cname [$ I];
$ Id = $ Cid [$ I];

$ Query = "update $ userstable set name = $ name where id = $ id ";
