Подсчет количества символов X

Question

Я экспериментирую с чем-то, что не работает explode (), поэтому я хочу попробовать что-то еще. Если у меня есть строка, как я могу посчитать количество символов в ней, скажем, comma как в ,

Answer 1

Попробуйте substr_count () :

substr_count($text, ',');

Answer 2

Вы можете использовать count_chars

Пример из руководства по PHP:

$data = "Two Ts and one F.";
foreach (count_chars($data, 1) as $i => $val) {
   echo "There were $val instance(s) of \"" , chr($i) , "\" in the string.\n";
}

There were 4 instance(s) of " " in the string.
There were 1 instance(s) of "." in the string.
There were 1 instance(s) of "F" in the string.
There were 2 instance(s) of "T" in the string.
There were 1 instance(s) of "a" in the string.
There were 1 instance(s) of "d" in the string.
There were 1 instance(s) of "e" in the string.
There were 2 instance(s) of "n" in the string.
There were 2 instance(s) of "o" in the string.
There were 1 instance(s) of "s" in the string.
There were 1 instance(s) of "w" in the string.
