poznámka:

if the optional lcg parameter is true, uniqid() will add additional "combined lcg" entropy at the end of the return value, which should make the results more unique.
pokud je volitelný argument lcg true, uniqid() přidá dodatečnou "kombinovanou lcg "entropii na konec své návratové hodnoty, což by mělo učinit výsledky ještě unikátnějšími.

the last example of expressions we'll deal with here is combined operator-assignment expressions. you already know that if you want to increment $a by 1, you can simply write '$a++' or '++$a'. but what if you want to add more than one to it, for instance 3? you could write '$a++' multiple times, but this is obviously not a very efficient or comfortable way. a much more common practice is to write '$a = $a + 3'. '$a + 3' evaluates to the value of $a plus 3, and is assigned back into $a, which results in incrementing $a by 3. in php, as in several other languages like c, you can write this in a shorter way, which with time would become clearer and quicker to understand as well. adding 3 to the current value of $a can be written '$a += 3'. this means exactly "take the value of $a, add 3 to it, and assign it back into $a". in addition to being shorter and clearer, this also results in faster execution. the value of '$a += 3', like the value of a regular assignment, is the assigned value. notice that it is not 3, but the combined value of $a plus 3 (this is the value that's assigned into $a). any two-place operator can be used in this operator-assignment mode, for example '$a -= 5' (subtract 5 from the value of $a), '$b *= 7' (multiply the value of $b by 7), etc.
v konstruktu '$b=$a=5 ;', je $a=5 platný výraz, ale samo o sobě to není konstrukt .'$b=$a=5;' je i platný konstrukt.
