I have this code:
$mob_numbers= array(02345674, 12345675, 22345676, 32345677);
echo ($mob_numbers[0]);
I wanted to print the first element of array but the output of that is:
641980
Why does this happen?
Why
System.out.println(Integer.valueOf("0")==Integer.valueOf("0"));
System.out.println(Integer.valueOf("1000")==Integer.valueOf("1000"));
returns
true
false
?
ps. I know == is different from equals()

echo "Parâmetro #1 deverá ser um inteiro!"
exit 0
