php常用方法汇总 1. PHP可阅读随机字符串
此代码将创建一个可阅读的字符串,使其更接近词典中的单词,实用且具有密码验证功能。
/************** *@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 $password; } 2. PHP生成一个随机字符串 如果不需要可阅读的字符串,使用此函数替代,即可创建一个随机字符串,作为用户的随机密码等。 /************* *@l - length of random string */ function generate_rand($l){ $c= "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"; srand((double)microtime()*1000000); for($i=0; $i<$l; $i++) { $rand.= $c[rand()%strlen($c)]; } return $rand; } 3. PHP编码电子邮件地址 使用此代码,可以将任何电子邮件地址编码为 html 字符实体,以防止被垃圾邮件程序收集。 function encode_email($email='info@domain.com', $linkText='Contact Us', $attrs ='class="emailencoder"' ) { // remplazar aroba y puntos $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 = ''; $part4 = ''; $encoded = ' |
