Aside from the array()
function itself,array_push()
is arguably the most common and useful function for manipulating arrays.
array_push()
takes two arguments: an array, and an element to add to the end of that array. Here's an example:
$fav_bands = array();
array_push($fav_bands, "Maroon 5");
array_push($fav_bands, "Bruno Mars");
array_push($fav_bands, "Nickelback");
array_push($fav_bands, "Katy Perry");
array_push($fav_bands, "Macklemore");
Another cool array function is count()
. Passing an array to count()
will return the number of elements in that array. Like this:
print count($fav_bands); // prints 5
