二十一个实用便利的PHP代码摘录（Twenty-one practical handy PHP code extracts）
Twenty-one practical handy PHP code extracts
1. PHP can read random strings
This code creates a readable string that makes it closer to the word in the dictionary, practical and has password authentication capabilities.
/**************
*@length - length, of, random, string (must, be, a, multiple, of, 2)
**************/
Function readable_random_string ($length = 6) {
$conso=array (B, C, d, F, g, H, J, K, L),
M, n, P, R, s, t, V, W, X, Y, Z);
$vocal=array (a, e, I, O, U);
$password=;
Srand ((double) microtime () *1000000);
$max = $length/2;
For ($i=1; $i=$max; $i++)
{
$password.=$conso[rand (0,19)];
$password.=$vocal[rand (0,4)];
}
Return $password;
}
2. PHP generates a random string
If you do not need a readable string, instead of using this function, you can create a random string that serves as the users random password.
/*************
*@l - length of random string
* /
Function generate_rand ($l) {
$c= ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789;
Srand ((double) microtime () *1000000);
For ($i=0; $i$l; $i++) {
$rand.=, $c[rand (),%strlen ($c)];
}
Return $rand;
}
3. PHP encode email address
With this code, you can encode any e-mail address into a HTML character entity to prevent collection by spam programs.
Function, encode_email ($email=info@, $linkText=Contact, Us, $attrs, =class=, emailencoder)
{
Aroba y Puntos / / remplazar
$email = str_replace (@ , @ , $email);
$email = str_replace (. ,. , $email);
$email = str_split ($email, 5);
$linkText = str_replace (@ , @ , $linkText);
$linkText = str_replace (. ,. , $linkText);
$linkText = str_split ($linkText, 5);
$part1 =a href= Ma;
$part2 =ilto:;
$part3 = $attrs . ;
$part4 =/a;
$encodedscript type= = text/javascript ;
$encoded = document.write ($part1);;
$encoded = document.write ($part2);;
Foreach ($email, as, $e)
{
$encoded = document.write ($e);;
}
$encoded = document.write ($part3);;
Foreach ($linkText, as, $l)
{
$encoded = document.w
