Why don't you try it out yourself? That code will produce a "_Parse error: syntax error, unexpected token "echo" ..._" – brombeer Nov 29 '21 at 11:43

When you prefix a number with a zero, like `$x = 025;`, PHP will read it as an octal number. Octal `25` is equal decimal `21` so the code above is equal to: `$x = 21; echo $x / 5;` which will be `4.2` – M. Eriksson Nov 29 '21 at 11:44

the output is 4.2 – Albert Logic Einstein Nov 29 '21 at 11:44

The octal numeral system, or oct for short, is the base-8 number system, and uses the digits 0 to 7, that is to say 10 represents 8 in decimal and 100 represents 64 in decimal.
25 = Whole
025 = Octal
025 in octal system = 21
so 21/5 = 4.2
