PHP常见方法封装总结
作者：PHP开源社区
这篇文章主要为大家介绍了PHP中常见的几个方法封装，文中的示例代码讲讲详细，对我们学习或工作有一定的参考价值，感兴趣的可以了解一下
1.get请求
function get_curl($url, $timeout = 5) {
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true );
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
$result = curl_exec( $ch );
curl_close($ch);
return $result;
}2.post请求
function post_curl($url, $data, $timeout = 5) {
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true );
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
$result = curl_exec( $ch );
curl_close($ch);
return $result;
}3.随机字符串
function random_str($len=10, $type=1){
switch($type){
case 2:
$chars='0123456789';
break;
case 3:
$chars='abcdefghijklmnopqrstuvwxyz';
break;
case 4:
$chars='ABDEFGHIJKLMNOPQRSTUVWXYZ';
break;
case 5:
$chars='abcdefghijklmnopqrstuvwxyzABDEFGHIJKLMNOPQRSTUVWXYZ';
break;
case 6:
$chars='abcdefghijklmnopqrstuvwxyz0123456789';
break;
default:
$chars='abcdefghijklmnopqrstuvwxyzABDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
break;
}
$str = '';
for ( $i = 0; $i <$len; $i++ ){
$str .= $chars[ mt_rand(0, strlen($chars) - 1) ];
}
return $str;
}4.返回json数据
function json_back($data, $is_exit = true) {
$callback = $_GET['callback'] ?? '';
if ($callback) {
echo '' . $callback . "(" . json_encode($data, JSON_UNESCAPED_UNICODE) . ")";
} else {
echo json_encode($data, JSON_UNESCAPED_UNICODE);
}
if ($is_exit) exit();
}5.数据过滤
function check_data($data){
if(is_array($data)){
foreach($data as $key => $v){
$data[$key] = $this->check_data($v);
}
}else{
$data = trim($data);
$data = strip_tags($data);
$data = htmlspecialchars($data);
$data = addslashes($data);
}
return $data;
}6.重定向
function redirect($url = 'https://blog.csdn.net/weixin_41635750'){
if (!headers_sent()) {
header("Location: {$url}");
exit();
}else{
$str = "<meta http-equiv='Refresh' content='0;URL={$url}'>";
exit($str);
}
}7.获取客户端ip
function get_real_ip() {
if(@$_SERVER["HTTP_ALI_CDN_REAL_IP"]){
$ip = $_SERVER["HTTP_ALI_CDN_REAL_IP"];
}
elseif (@$_SERVER["HTTP_X_FORWARDED_FOR"] ?: false) {
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
$ips = explode(',', $ip);
$ip = $ips[0];
} elseif (@$_SERVER["HTTP_CDN_SRC_IP"] ?: false) {
$ip = $_SERVER["HTTP_CDN_SRC_IP"];
} elseif (getenv('HTTP_CLIENT_IP')) {
$ip = getenv('HTTP_CLIENT_IP');
} elseif (getenv('HTTP_X_FORWARDED')) {
$ip = getenv('HTTP_X_FORWARDED');
} elseif (getenv('HTTP_FORWARDED_FOR')) {
$ip = getenv('HTTP_FORWARDED_FOR');
} elseif (getenv('HTTP_FORWARDED')) {
$ip = getenv('HTTP_FORWARDED');
} else {
$ip = $_SERVER['REMOTE_ADDR'];
}
$ip = str_replace(array('::ffff:', '[', ']'), array('', '', ''), $ip);
return $ip;
