Any one can explain to me? why it's returning 83?

Question

$k=0123;echo $k;

Majid Hameed · Answer

Yes anything that starts with0 is an octal integer.

If you don't want to store string and want to store number then following are2 options.

$k =0123.00;

OR if you want to stick with integer then you can do casting.

$k = (int)0123.00;

Because it's assigning $k to the octal value of0123 which is83.

0123 =83 in octal

Instead, try to store0123 as a string e.g. $k = "0123";
