Count word frequency in a text? [duplicate]

Answer 1

Your best bet are these:

• str_word_count — Return information about words used in a string
• array_count_values — Counts all the values of an array

Example

$words = 'A string with certain words occuring more often than other words.';
print_r( array_count_values(str_word_count($words, 1)) );

Output

Array
(
    [A] => 1
    [string] => 1
    [with] => 1
    [certain] => 1
    [words] => 2
    [occuring] => 1
    [more] => 1
    [often] => 1
    [than] => 1
    [other] => 1
)
