使用uniqid生成:可以使用uniqid()函数来生成一个唯一的ID,然后通过substr函数截取前8位作为生成的8位字符串。```php// 生成8位随机字符串function generateRandomString() { $characters = uniqid('', true); $randomString = substr($characters, 0, 8); re
function generateRandomString($length = 6) { $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'; $randomString = ''; for ($i = 0; $i < $length; $i++) { $randomString .= $characters[rand(0, strlen($characters) - 1)]; } return $randomString; } echo gene...
$str .= genRandomString(25); $str .= ""; $str .= genRandomString(25); echo $str; ?> 例子2: 复制代码 代码如下: <?php /* Generate Password * Length : 8 */ $str = "0123456789abcdefghijklmnopqrstuvwxyz"; // 输出字符集 $n = 8; // 输出串长度 $len = strlen($str)-1; for...
90)); // 生成65到90之间的ASCII码对应的字符(大写字母) $randomString .= $randomChar; // 将生成的字符拼接到字符串上}echo $randomString; // 输出生成的随机字符```方法二:使用array_rand()函数生成随机字符```php$length = 10; // 生成字符的长度$characters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJ...

This includes any functionality requiring access at a specific index, since random access is not possible in a string whose number of bytes will not necessarily match the number of characters. Affected functions include: mb_substr(), mb_strstr(), mb_strcut(), mb_strpos(), etc.up down ...
