Yes, this has been mentioned in this thread. But with serialize/ unserialize, you can run into other problems that may be more confusing/difficult to troubleshoot. e.g.: http://www.php.net/serialize > >As you can see, the original array : > >$arr["20041001103319"] = "test" > > > >after serialize/unserialize is: > >$arr[683700183] = "test" > > yepp, and i can explain it. > > the internal compiler of php does not hit anys rule wich foces him > to make that number a string during serialisation. since it becomes > an integer and php supports 32bit interger not arbitary bitwidth > this is what happens: > > "20041001103319" > equals hexadecimal: > > 0x123A28C06FD7h > > if you cut away the frontpart cutting down to 32bis, > you get: > > 0x28C06FD7h > > wich equals 683700183. For simple arrays, I prefer storing everything as a simple imploded string. YMMV.
