Strings need a null terminator else you will run into all sorts of problems. Means the sizes of your strings need to be at least 12 and 6 chars long, respectively. Also use sizeof instead of inserting the size literally. Sizeof is an operator, not a function, and has no impact on performance. Furthermore, instead of calling random(9) over and over again you can just do this:

PHP код:

format(bankszamla, sizeof(bankszamla), "%03d-%03d-%03d", random(1000), random(1000), random(1000)); 


PHP код:

format(bankjelszo, sizeof(bankjelszo), "%05d", random(100000));
