對一段英文文本的信息，統計其中大寫字母，小寫字母，空格，標點符號的個數

<?php
$manuscript = "Where there is a will, there is a way.";//字符串文本
$smallLetter = 0;
$capitalLetter = 0;
$blank = 0;
$punctuation = 0;

$num=strlen($manuscript);
$arr=str_split($manuscript);//字符串分割為數組
foreach($arr as $key=>$value)
{
if($value==‘ ‘)
{
$blank+=1;
}
if(‘a‘<=$value&&$value<=‘z‘)
{
$smallLetter+=1;
}
if(‘A‘<=$value&&$value<=‘Z‘)
{
$capitalLetter+=1;
}
}
$punctuation=$num-$smallLetter-$capitalLetter-$blank;

echo ‘大寫字母個數：‘.$capitalLetter."<br>";
echo ‘空格個數：‘.$blank."<br>";
echo ‘標點個數：‘.$punctuation."<br>";
