Question

I have the following array. It contains nicknames and names:

$nickAndNames = array( 
    array( "Johnie", "John Larson" ),
    array ("Maggie", "Margaret London" ),
    array("Nic","Nicholas Carradine")
);

Can you please help me to print just the first elements? I mean Johnie, Maggie, Nic.

Answer 1

Each element of the array is another array. Each element of this inner array in turn contains 2 elements: element 0 (a string, the nickname) and element 1 (another string, the name). Therefore, you’d first need to loop through the $nicksAndNames array, and then display the inner array’s first element (which is element 0):

// loop through $nickAndNames and assign, in turn, each inner array
// to a variable named $nickAndName
foreach ($nickAndNames as $nickAndName) {
    // this $nickAndName variable now contains the inner array, something like:
    // array("Johnie", "John Larson"), so "Johnie" is the first element,
    // element 0
    echo $nickAndName[0];
}
