I would like to insert some value into a table, which has an auto-incrementing field as a primary key. Then I want to retrieve the ID by using mysql_insert_id() and use this ID as a foreign key in another table.

Problem is I am not sure how to keep things clean without calling lots and lots of queries per page. To illustrate my example, I'll imagine I am designing a stack overflow like site: I have ...

I'm looking for a way to generate a big random number with PHP, something like: mt_rand($lower, $upper); The closer I've seen is gmp_random() however it doesn't allow me to specify the lower and upper boundaries only the number of bits per limb (which I've no idea what it is). EDIT: Axsuuls answer seems to be pretty close to what I w...

Since there doesn't seem to be any support for optimistic locking in CakePHP, I'm taking a stab at building a behaviour that implements it. After a little research into behaviours, I think I could run a query in the beforeSave event to check that the version field hasn't changed. However, I'd rather implement the check by changing the ...

Uh, and it's broken: I had a perfectly working regex that allowed all the numbers, letters and only e-mail relevant punctuation (._-@) to sanitize my email fields, and then I thought it would be nice adding a proper email regex, checking for the correct pattern.
