一、发送请求头

//发送地址
$url = 'http://127.0.0.1/2.php';
//请求头内容
$headers = array(
    'Authorization: '.$basic,
    'suibianzhi: '.$basic,
);
//使用curl发送
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
curl_close($ch);
echo $result;

二、接收并打印请求头

$headers = array();
foreach ($_SERVER as $key => $value) {
    if ('HTTP_' == substr($key, 0, 5)) {
        $headers[str_replace('_', '-', substr($key, 5))] = $value;
    }
}    
echo '<pre>';
print_r($headers);

PHP判断访问终端，电脑或手机访问
函数代码：

//判断电脑或手机访问
function is_mobile(){
    $user_agent = $_SERVER['HTTP_USER_AGENT'];
    $mobile_agents = Array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi","android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio","au-mic","avantogo","becker","benq","bilbo","bird","blackberry","blazer","bleu","cdm-","compal","coolpad","danger","dbtel","dopod","elaine","eric","etouch","fly ","fly_","fly-","go.web","goodaccess","gradiente","grundig","haier","hedy","hitachi","htc","huawei","hutchison","inno","ipad","ipaq","ipod","jbrowser","kddi","kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo","mercator","meridian","micromax","midp","mini","mitsu","mmm","mmp","mobi","mot-","moto","nec-","netfront","newgen","nexian","nf-browser","nintendo","nitro","nokia","nook","novarra","obigo","palm","panasonic","pantech","philips","phone","pg-","playstation","pocket","pt-","qc-","qtek","rover","sagem","sama","samu","sanyo","samsung","sch-","scooter","sec-","sendo","sgh-","sharp","siemens","sie-","softbank","sony","spice","sprint","spv","symbian","tablet","talkabout","tcl-","teleca","telit","tianyu","tim-","toshiba","tsm","up.browser","utec","utstar","verykool","virgin","vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce","wireless","xda","xde","zte");
    $is_mobile = false;
    foreach ($mobile_agents as $device) {
        if (stristr($user_agent, $device)) {
            $is_mobile = true;
            break;
        }
    }
    return $is_mobile;
}

调用方式：

//返回true或false
is_mobile();

PHP取当前年、月、日开始时间戳和下年、月、日开始时间戳函数
函数代码：

/**
 * 获取时间戳
 * $Ymd = Y 年
 * $Ymd = m 月
 * $Ymd = d 日
 * $Ymd = NULL 当前时间戳
 * $xia = true 是否取下次开始时间戳：取下年开始时间戳 或者下月开始时间戳  或者明日开始时间戳
 */
function getTime($Ymd=NULL,$xia=false){
    if($Ymd=='Y' && $xia==true){
        //取下个年度开始时间戳
        return strtotime((date('Y',time())+1).'-01-01 00:00:00');
    }
    else if($Ymd=='Y'){
        //取本年度开始时间戳
        return strtotime(date('Y',time()).'-01-01 00:00:00');
    }
    else if($Ymd=='m' && $xia==true){
        //取下个月度开始时间戳
        $xiayue_nianfen    =    date('Y',time());
        $xiayue_yuefen    =    date('m',time());
        if($xiayue_yuefen==12){
            $xiayue_nianfen    +=    1;    //如果月份等于12月，那么下月年份+1
            $xiayue_yuefen    =    1;    //如果月份等于12月，那么下月月份=1月
        }
        else{
            $xiayue_yuefen    +=    1;    //如果月份不是12月，那么在当前月份上+1
        }
        return strtotime($xiayue_nianfen.'-'.$xiayue_yuefen.'-01 00:00:00');
    }
    else if($Ymd=='m'){
        //取本月度开始时间戳
        return strtotime(date('Y-m',time()).'-01 00:00:00');
    }
    else if($Ymd=='d' && $xia==true){
        //取明日开始时间戳
        return strtotime(date('Y-m-d',time()).' 00:00:00')+86400;
    }
    else if($Ymd=='d'){
        //取今日开始时间戳
        return strtotime(date('Y-m-d',time()).' 00:00:00');
    }
    else{
        //取当前时间戳
        return time();
    }
}

调用代码：

getTime('Y');        //当前年的时间戳
getTime('m');        //当前月的时间戳
getTime('d');        //当前日的时间戳
getTime('Y',true);    //明年的时间戳
getTime('m',true);    //下月的时间戳
getTime('d',true);    //明日的时间戳
getTime();            //当前的时间戳

PHP生成验证码图片

<?php
// 创建画布
$width = 120;   // 规定画布的宽高
$height = 45;
$image = imagecreatetruecolor($width, $height);  // 创建一幅真彩色图像
// 添加一些即将用到的颜色
$white = imagecolorallocate($image, 0xf2, 0xec, 0xe0);
$orange = imagecolorallocate($image, 0xff, 0xa5, 0x4c);
// 对画布背景填充颜色
imagefill($image, 0, 0, $white);

//mt_rand  获取随机数 mt_rand(min, max);
    function  str_rand(){
        $str="abcdefghijkmnpqrstuvwxyz0123456789ABCDEFGHIGKLMNPQRSTUVWXYZ";
        $rand="";
        for($i=0; $i<5; $i++){//获取5个随机的字符串
            $rand .= $str[mt_rand(0, strlen($str)-1)];  //如：随机数为30  则：$str[30]
        }
        return $rand;
    }
$verifyCode=str_rand();
// 画一串字符串在画布上
imagestring($image, 10, 10, 10, "$verifyCode", $orange);
// 通知浏览器输出的是图像（png类型）
header('Content-Type: image/png');
// 输出到浏览器
imagepng($image);
// 释放图像资源

备注：建议大家用mt_rand()，而不是rand()，前者效率更高
