如何使用PHP计算网页上出现单词的次数[重复]

Question

This question already has an answer here:

• Count how often the word occurs in the text in PHP 4 answers

I need a script that will return a count of how many times a specified word appears on webpage. Does anyone know how to do this with PHP? The code will be like this:

<?php
$url="watever.com";
the script here
echo(result);
?>

I do have this little bit that just gives a count of how many times every word on the webpage appears but I am not quite sure how to modify it for just one word.

$str = file_get_contents('http://www.example.com/');
print_r(array_count_values(str_word_count(strip_tags(strtolower($str)), 1)));

</div>

Answer 1

Try using substr_count:

$result = (substr_count(strip_tags($str),"mycoolword"));
