How do I separate and style hit counter digits with php methods? - php

Question

I am using this PHP code to get and display the number of visitors to my site (hit counter).
Currently it is set up to display that number in a single block, i.e. - I would like to display each digit in its own html tag in order to style each number differently.
I have experimented with explode, and substr on the $allHits var, but am not getting good results.
Any Ideas?

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

Would using a foreach loop work, like this:
$array_allHits = explode(" ",$allHits);
foreach ($array_allHits as $display_digits) {
echo $display_digits[0];
}

Answer 1

You could use a for-loop.
for ($i = 0; $i < strlen((string) $allHits); $i++) {
echo '<span>' . $allHits[$i] . '</span>';
}
The above code will output <span>{number}</span> for every digit in the hit count.
It will loop through every character in the string, similar as to how array indexes are treated.

Answer 2

$totalHits = 125655;
foreach(str_split((string)$totalHits) as $key => $val) {
echo "<span class='position_{$key}'>{$val}</span>";
}
Add styles in you css as below:
.position_0 {
color: red;
}
.position_1 {
color: blue;
}
.position_2 {
color: yellow;
}
