From the manual:
array array_count_values ( array input)
array_count_values() returns an array using the values of the input
array as keys and their frequency in input as values.
Example 1. array_count_values() example
<?php
$array = array(1, "hello", 1, "world", "hello");
print_r(array_count_values($array));
?>
The printout of the above program will be:
Array
(
[1] => 2
[hello] => 2
[world] => 1
)

I'd like to know how many occurences of each there are. For instance:
$fruits = array(
"lemon",
"orange",
"banana",
"apple",
"orange",
"banana",
"orange" );
And I'd like to create this:
$fruit_count = array(
"lemon" => 1,
"orange" => 3,
"banana" => 2,
"apple" => 1 );
My current plan of action is to create $fruit_count, and check if
$fruits[0] is listed in it. If not, then I'll add it with a value of
1. If it is already listed then I'll just increase it's number. Ditto
for $fruits[1] and so on...
Has someone cleverer than myself found a better way of doing this?
This function will be used as a word count for text documents, and
some of them have over 5000 words. So if there's a better way of doing
this I'd love to know. Thanks.
