 |
|
Hiding details of a word is important sometimes. For example unauthenticated visitors of a service should not see the full details of a owner's name.
Inspired by google's behavior in hiding user names, I am publishing this code to suspense a word. It randomly replaces some letters of a word with a dot (.) making it somewhat harder to guess.
You may download modifier.suspense.php here
| Code: | function smarty_modifier_suspense($word='')
{
# suspense using this set of character(s)
$suspense_character = '_';
$letters = str_split($word, 1);
if(count($letters) <= 2)
{
# Hide all characters when the total length is too small.
foreach($letters as $l => $letter)
{
$letters[$l] = $suspense_character;
}
}
else
{
foreach($letters as $l => $letter)
{
if($l%3==mt_rand(0, 2))
{
# Randomly hide some letters
$letters[$l] = $suspense_character;
}
}
# Make sure to suspense, even if mt_rand() genrated all zeros.
$letters[1] = $suspense_character;
}
return implode('', $letters);
} |
Usage examples
| Code: | | {$username|suspense} |
if you take the below words to suspense:
| Code: | $words = array(
'',
'a',
'kp',
'jil',
'jack',
'jackie',
'william',
); |
it will produce unpredictable set of word in return. Here are the samples:
= _
a = _
kp = __
jil = j_l
jack = ___k
jackie = j__kie
william = w___iam
