The entrypoint should belib/random.phpdirectly, not any of the other files in/lib. Usage This library exposes theCSPRNG functions added in PHP 7for use in PHP 5 projects. Their behavior should be identical. try{$string=random_bytes(32); }catch(TypeError$e) {// Well, it's an integer,...
1.说明 string random_bytes( int $length) 生成适合于加密使用的任意长度的加密随机字节字符串,例如在生成salt、密钥或初始化向量时。 2.环境 PHP version >=7 3.参数 length: int类型,生成指定大小的随机字符串(单位:字节) 4.返回值 返回值为ASCII字符串 5.实例 // 一般配合bin2hex()函数使用 // bin2hex...
示例 ¶ 示例#1 random_bytes() example <?php$bytes = random_bytes(5);var_dump(bin2hex($bytes));?> 以上示例的输出类似于: string(10) "385e33f741" 参见 ¶ Random\Randomizer::getBytes() - Get random bytes random_int() - 获取生成加密安全、均匀分布的整数 bin2hex() - 将二进制数据转换...
php $bytes=random_bytes(5);var_dump(bin2hex($bytes));?> The above example will output something similar to: 代码语言:javascript 复制 string(10)"385e33f741" See Also random_int() - Generates cryptographically secure pseudo-random integers openssl_random_pseudo_bytes() - Generate a pseudo-rand...

5. 调用openssl_random_pseudo_bytes()函数,确保不再出现undefined function错误 按照上述步骤操作后,你应该能够成功调用openssl_random_pseudo_bytes()函数而不会遇到“undefined function”错误。 如果问题仍然存在,请检查你的PHP配置文件(如php.ini)是否被正确加载,以及是否有其他配置或权限问题导致OpenSSL扩展无法正常工...
