对一段英文文本的信息，统计其中大写字母，小写字母，空格，标点符号的个数
$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);//字符串分割为数组
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-$blank;
echo ‘小写字母个数：‘.$smallLetter."
";
echo ‘大写字母个数：‘.$capitalLetter."
";
echo ‘空格个数：‘.$blank."
";
echo ‘标点个数：‘.$punctuation."
";
?>
