我正在使用这个PHP代码来获取和显示我网站的访问者数量（点击计数器）。目前，它被设置为在单个块中显示该数字，即 - 我想在其自己的 html 标签中显示每个数字，以便以不同的方式设置每个数字的样式。
我已经尝试过爆炸，并在 var $allHits上进行 substr，但没有得到很好的结果。有什么想法吗？

-------- ++ simPHP ++ --------
A simple PHP hit counter.
Description:
simPHP counts both regular and unique views on multiple
webpages. The stats can be displayed on any PHP-enabled
webpage. You MUST have read/write permissions on files.

/*----------CONFIG----------*/
// NOTE: If you change any config after using simphp,
// remove the old files.
// Relative URL of text file that holds hit info:
$lf_name = "hits.txt";
// Save new log file each month
// 0 = No
// 1 = Yes
$monthly = 1;
// Path to store old files:
// Default for June, 2012:
// oldfiles/6-12.txt
$monthly_path = "oldfiles";
// Count unique hits or all hits:
// 0 = All hits
// 1 = Unique hits
// 2 = Both
$type = 2;
// Text to display
// before all hits.
$beforeAllText = "Site Visitors: ";
// Before unique hits.
$beforeUniqueText = "Unique Visits: ";
// Display hits on this page:
// 0 = No
// 1 = Yes
$display = 1;
// Only change this if you are recording both values.
// Separator for unique and all hits display - use HTML tags! (line break is default)
$separator = "<br '>";
// Default would output:
// Visits: 10
// Unique Visits: 10

使用 foreach 循环会起作用吗，如下所示：
$array_allHits = explode(" ",$allHits);
foreach ($array_allHits as $display_digits) {
echo $display_digits[0];
}
你可以
使用 for 循环。
for ($i = 0; $i < strlen((string) $allHits); $i++) {
echo '<span>' . $allHits[$i] . '</span>';
}
上面的代码将为命中计数中的每个数字输出<span>{number}</span>。它将遍历字符串中的每个字符，类似于数组索引的处理方式。
$totalHits = 125655;
foreach(str_split((string)$totalHits) as $key => $val) {
echo "<span class='position_{$key}'>{$val}</span>";
}
在 css 中添加样式，如下所示：
.position_0 {
color: red;
}
.position_1 {
color: blue;
}
.position_2 {
color: yellow;
}
