Maybe This is dead-simple stupid question, but how PHP translate our code ?
- by justjoe
i got this code
`
//
// prints out "Hello World!"
//
hello_world(); //First call
function hello_world()
{
echo "Hello World!<br/>\n";
}
hello_world(); //second call
?>`
Both of 'hello_world' call will print out the same result. It's easily to understand why the second call will be output 'Hello world', but how…
