Re: Re: Declaring arrays? Good practice?

However.... For loops: $new_array= array(); foreach($old array as $value){ $new_array= $value: } Otherwise, all you'll get it the last assignment of $new_array as a variable, not an array.

which is exactly what you get if yuou run the code above - after the foreach loop $new_array will be set to the value of the last item of $old_array. regardless of whether you init the var you still have to use the square-bracket notation to add items to the array.

You can also use; foreach($old array as $value){ $new_array[]= $value: } But sometimes, if the expression is a bit fancy in the loop and you are using $keys, it is easy to make a mistake. Al.......... Michael Hulse wrote:

Sorry if this question sounds noobish: $foo = array(); // Declare first, good practice. $foo = array('one', 'two', 'three'); Using above as example, is it good to always declare the array first? I usually/always declare my arrays first, but sometimes I get a bit confused... for example: function give_foo() {

    $the_foo = array(); // Declare first, good practice.
    $the_foo = array('one', 'two', 'three');
    // Do some stuff here...
    return $the_foo;

} $foo = give_foo(); // Declare $foo also? So, should I declare $foo as array and then give it the value of the function? Example: $foo = array(); // Declare first, good practice. $foo = give_foo(); That seems kinda redundant. Thoughts? Sorry if this is a stupid question... I am self-taught, and I am trying to shake all my bad coding habits.
