calling an array

[ollie007]

hi hi, just some clarification please

 

1. do i need to declare an array. eg $array = array();

 

or just add to an array: eg. $array[] = $var;

 

2. if i have an array: $array = (1,2,3,4,5);

 

and i declare $array[$key] to get my values.

 

Now if the array happens to have one value $array = (1);

 

can i call this value simply with $array

 

eg if ($array == 1)

 

OR do i need to specify the key?

 

eg if ($array[0] == 1)

 

cheers

You should declare it first

 

2. if i have an array: $array = (1,2,3,4,5);

 

and i declare $array[$key] to get my values.

 

Now if the array happens to have one value $array = (1);

You use the key

 

EDIT: it maybe worth reading current() and count()
