如何计算两个数组中出现的单词？ （用php）

Question

if I have an array of two arrays

D[0] = array ("I", "want", "to", "make", "cake", "and", "make", "juice")
D[1] = array ("Sister", "want", "to", "takes", "the", "cake", "that", "i", "made")
how to count the occurrences of words that are in both arrays?

eg output:
word | array[0] | array[1]
I : 1 | 1
want : 1 | 1
to : 1 | 1
make : 2 | 0
cake : 1 | 1
and : 1 | 0
juice : 1 | 0
sister : 0 | 1
takes : 0 | 1
the : 0 |1
that : 0 | 1
made : 0 | 1

Answer 1

You can just use array_count_values():

$count[0] = array_count_values($D[0]); //Assuming you meant to have D as a variable in your question
$count[1] = array_count_values($D[1]);

The key is the word and the value is the number.
