TP3.2框架中如何使用多个mysql函数 如FIND_IN_SET 和 !FIND_IN_SET 数据查询中可能会用到数据表中的多个字段去做匹配 可能会用到多个FIND_IN_SET 也可能需要拼接多个条件$user_ids = [1,2,3]; //获取需要匹配的值 if ($user_ids ){ foreach ($user_ids as $val){ $map[] = " FIND_IN_SET($val,show_user_id) "; } } $where['_string'] = implode(" OR ",$map); # 预览sql效果： WHERE FIND_IN_SET('1', show_user_id) OR FIND_IN_SET('2', show_user_id) OR FIND_IN_SET(3, show_user_id) 但是如果我们想除了这个函数还有其他函数要使用的时候并且$where['_string']已经被使用的时候怎么拼接？ $where['_logic'] = 'or';//and 或者 OR 就是看你的需要 $map['_string'] = " !FIND_IN_SET(4,show_user_id) "; $where['_complex'] = $map; # 预览sql效果： WHERE FIND_IN_SET('1', show_user_id) OR FIND_IN_SET('2', show_user_id) OR FIND_IN_SET(3, show_user_id) AND ( ( !FIND_IN_SET(4, show_user_id) //就是与FIND_IN_SET相反的意思 ) ) -
【laravel】 操作文件上传 1、获取上传的文件$file=$request->file('file');2、获取上传文件的文件名（带后缀，如abc.png）$filename=$file->getClientOriginalName();3、获取上传文件的后缀（如abc.png，获取到的为png）$fileextension=$file->getClientOriginalExtension();4、获取上传文件的大小$filesize=$file->getClientSize();5、获取缓存在tmp目录下的文件名（带后缀，如php8933.tmp）$filaname=$file->getFilename();6、获取上传的文件缓存在tmp文件夹下的绝对路径$realpath=$file->getRealPath();7、将缓存在tmp目录下的文件移到某个位置，返回的是这个文件移动过后的路径$path=$file->move(path,newname);move()方法有两个参数，第一个参数是文件移到哪个文件夹下的路径，第二个参数是将上传的文件重新命名的文件名8、检测上传的文件是否合法，返回值为true或false$file->isValid()

【PHP】RSA非对称加密解密 PHP服务端与客户端交互或者提供开放API时，通常需要对敏感的数据进行加密，这时候rsa非对称加密就能派上用处了。举个通俗易懂的例子，假设我们再登录一个网站，发送账号和密码，请求被拦截了。密码没加密，那攻击者就直接拿到了密码，这是最搓的。密码加密了，是不可逆加密，那攻击者只需要模拟那个请求即可登录。密码加密了，是可逆加密，其中携带有时间等参数，后台可以根据时间等参数来判断是否有效，但因为是在前端加密，其加密方式也能在代码中找到，找到加密方式就可以得出解密方式。但是如果我们使用非对称加密就可以避免以上问题。非对称加密算法需要两个密钥来进行加密和解密，这两个秘钥是公开密钥（public key，简称公钥）和私有密钥（private key，简称私钥）。工作过程如下，甲乙之间使用非对称加密的方式完成了重要信息的安全传输。 乙方生成一对密钥（公钥和私钥）并将公钥向其它方公开。得到该公钥的甲方使用该密钥对机密信息进行加密后再发送给乙方。乙方再用自己保存的另一把专用密钥（私钥）对加密后的信息进行解密。乙方只能用其专用密钥（私钥）解密由对应的公钥加密后的信息。在传输过程中，即使攻击者截获了传输的密文，并得到了乙的公钥，也无法破解密文，因为只有乙的私钥才能解密密文。 同样，如果乙要回复加密信息给甲，那么需要甲先公布甲的公钥给乙用于加密，甲自己保存甲的私钥用于解密。在非对称加密中使用的主要算法有：RSA、Elgamal、背包算法、Rabin、D-H、ECC（椭圆曲线加密算法）等。下面我们通过一个例子来说明如何用PHP来实现RSA的加密解密。<?php class Rsa { public $privateKey = ''; public $publicKey = ''; public function __construct() { $resource = openssl_pkey_new(); openssl_pkey_export($resource, $this->privateKey); $detail = openssl_pkey_get_details($resource); $this->publicKey = $detail['key']; } public function publicEncrypt($data, $publicKey) { openssl_public_encrypt($data, $encrypted, $publicKey); return $encrypted; } public function publicDecrypt($data, $publicKey) { openssl_public_decrypt($data, $decrypted, $publicKey); return $decrypted; } public function privateEncrypt($data, $privateKey) { openssl_private_encrypt($data, $encrypted, $privateKey); return $encrypted; } public function privateDecrypt($data, $privateKey) { openssl_private_decrypt($data, $decrypted, $privateKey); return $decrypted; } } $rsa = new Rsa(); echo "公钥：\n", $rsa->publicKey, "\n"; echo "私钥：\n", $rsa->privateKey, "\n"; // 使用公钥加密 $str = $rsa->publicEncrypt('hello', $rsa->publicKey); // 这里使用base64是为了不出现乱码，默认加密出来的值有乱码 $str = base64_encode($str); echo "公钥加密（base64处理过）：\n", $str, "\n"; $str = base64_decode($str); $pubstr = $rsa->publicDecrypt($str, $rsa->publicKey); echo "公钥解密：\n", $pubstr, "\n"; $privstr = $rsa->privateDecrypt($str, $rsa->privateKey); echo "私钥解密：\n", $privstr, "\n"; // 使用私钥加密 $str = $rsa->privateEncrypt('world', $rsa->privateKey); // 这里使用base64是为了不出现乱码，默认加密出来的值有乱码 $str = base64_encode($str); echo "私钥加密（base64处理过）：\n", $str, "\n"; $str = base64_decode($str); $pubstr = $rsa->publicDecrypt($str, $rsa->publicKey); echo "公钥解密：\n", $pubstr, "\n"; $privstr = $rsa->privateDecrypt($str, $rsa->privateKey); echo "私钥解密：\n", $privstr, "\n"; 大家执行一下可以看到公钥加密的数据，只有私钥能解密，反之亦然，私钥加密的数据只有公钥能解码。这是PHP端的实现，可用在第三方跟平台之间的数据传输，但如果是前端传到后端该怎么办呢，搜索了一下，发现了这个库https://github.com/travist/jsencrypt使用jsencrypt加密解密的例子如下：<!DOCTYPE html> <html> <head> <title>JSEncrypt Example</title> <base id="basetag" href="/jsencrypt-2.3.0/"> <meta http-equiv="Content-Type" content="text/html;

【Typecho】Typecho 添加是否被百度收录 我们是否经常在一些网友的博客内容页看到 "百度已收录" 等字样？其实这样加上去有多少效果也没有多少，但是对于有些个人来说他喜欢的，或者可以在考核编辑的时候可以看看他们的文案是否达到有效的收录率。如果你有使用 Typecho 程序，可以通过下面的方法实现。第一、添加脚本/** * 提示文章百度是否收录 * */ function baidu_record() { $url='http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; if(checkBaidu($url)==1){ echo "百度已收录"; }else{ echo "<a style=\"color:red;\" rel=\"external nofollow\" title=\"点击提交收录！\" target=\"_blank\" href=\"http://zhanzhang.baidu.com/sitesubmit/index?sitename=$url\">百度未收录</a>";} } function checkBaidu($url) { $url = 'http://www.baidu.com/s?wd=' . urlencode($url); $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $rs = curl_exec($curl); curl_close($curl); if (!strpos($rs, '没有找到')) { //没有找到说明已被百度收录 return 1; } else { return -1; } } 将脚本添加到当前 Typecho 主题中的 Functions.php 文件中。第二、调出效果<?php echo baidu_record() ?>在合适的位置调出即可，如果我们有特定样式可以用一个 span 标签包含处理。
