php - 计算使用fopen和fpassthru在网页中显示单词的次数

Question

Another question: Here's my code atm:

$fp = fopen("https://********", 'r', false, $context);
fpassthru($fp);
fclose($fp);

$tmp = count_values($fp);
$cnt = $tmp[typelabel];
echo $cnt;

I want this code to count the number of times the word 'typelabel' appears in the variable $fp. I believe the count function only works on arrays, so any ideas? Also, would this work if I didnt print out the page contents (if i removed fpassthru?) Thanks

Answer 1

What you are looking for is substr_count.

$typelabel_count = substr_count($data, 'typelabel');

Sidenote: A better way to read the data of an url is to just use file_get_contents.
