[PHP知识库]php 常用方法封装

文件处理

• 打印输出数据到文件

    function p($data, $force = false, $file = null)
    {
        is_null($file) && $file = env('runtime_path') . date('Ymd') . '.txt';
        $str = ((is_string($data) ? $data : (is_array($data) || is_object($data))) ? print_r($data, true) : var_export($data, true)) . PHP_EOL;
        $force ? file_put_contents($file, $str) : file_put_contents($file, $str, FILE_APPEND);
    }

• 打印log日志

function wx_log($domainname, $filename)
    {
        $years = date('Y-m-d');
        //设置路径目录信息
        $url = $filename . date('Ymd') . 'log.txt';
        $dir_name = dirname($url);
        //目录不存在就创建
        if (!file_exists($dir_name)) {
            //iconv防止中文名乱码
            $res = mkdir(iconv("UTF-8", "GBK", $dir_name), 0777, true);
        }
        $fp = fopen($url, "a");//打开文件资源通道 不存在则自动创建
        fwrite($fp, date("Y-m-d H:i:s") . var_export($domainname, true) . "\r\n");//写入文件
   
    }

• 图片转base64

function base64EncodeImage ($image_file) {
  $base64_image = '';
  $image_info = getimagesize($image_file);
  $image_data = fread(fopen($image_file, 'r'), filesize($image_file));
  $base64_image = 'data:' . $image_info['mime'] . ';base64,' . chunk_split(base64_encode($image_data));
  return urlencode($base64_image);
}

• 获取图片size

function getUriLen($uri,$user='',$pw='')
    {
        ob_start();

        $ch = curl_init($uri);
        curl_setopt($ch, CURLOPT_HEADER, 1);
        curl_setopt($ch, CURLOPT_NOBODY, 1);  //nobody是关键
        if (!empty($user) && !empty($pw))
        {
            $headers = array('Authorization: Basic ' . base64_encode($user.':'.$pw));
            curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        }
        $okay = curl_exec($ch);
        curl_close($ch);

        $head = ob_get_contents();
        ob_end_clean();

        $regex = '/Content-Length:\s+(.+)/';
        preg_match($regex, $head, $matches);

        return $matches[1];
    }

• 获取验证码(通过GD库)$code圖片驗證碼名稱

function getCode($num,$w,$h,$code_name) {
    $code = "";
    for ($i = 0;$i < $num; $i++){
        $code .= rand(0, 9);
    }
    //4位验证码也可以用rand(1000,9999)直接生成
    //将生成的验证码写入session，备验证时用
    Cache::set($code_name,$code,600);
    //创建图片，定义颜色值
    header("Content-type: image/PNG");
    $im = imagecreate($w, $h);
    $black = imagecolorallocate($im, 0, 0, 0);
    $gray = imagecolorallocate($im, 200, 200, 200);
    $bgcolor = imagecolorallocate($im, 255, 255, 255);
    //填充背景
    imagefill($im, 0, 0, $gray);
    //画边框
    imagerectangle($im, 0, 0, $w-1, $h-1, $black);
    //随机绘制两条虚线，起干扰作用
    $style = array ($black,$black,$black,$black,$black, $gray,$gray,$gray,$gray,$gray);
    imagesetstyle($im, $style);
    $y1 = rand(0, $h);
    $y2 = rand(0, $h);
    $y3 = rand(0, $h);
    $y4 = rand(0, $h);
    imageline($im, 0, $y1, $w, $y3, IMG_COLOR_STYLED);
    imageline($im, 0, $y2, $w, $y4, IMG_COLOR_STYLED);
    //在画布上随机生成大量黑点，起干扰作用;
    for ($i = 0; $i < 80; $i++) {
        imagesetpixel($im, rand(0, $w), rand(0, $h), $black);
    }
    //将数字随机显示在画布上,字符的水平间距和位置都按一定波动范围随机生成
    $strx = rand(3, 8);
    for ($i = 0; $i < $num; $i++) {
        $strpos = rand(1, 6);
        imagestring($im, 5, $strx, $strpos, substr($code, $i, 1), $black);
        $strx += rand(8, 12);
    }
    imagepng($im);//输出图片
    imagedestroy($im);//释放图片所占内存
}

        } else {
            return json_encode($value, JSON_UNESCAPED_UNICODE);

    {
        
        $json_str = str_replace('＼＼', '', $json_str);
        
        $out_arr = array();

• json解析

function json_encrypt($str)

    $str = trim($str,'{}');
    $str = str_replace('\"',"^",$str);
    $str = str_replace('"',"",$str);
    $str = '['.str_replace('^','"',$str).']';

    if($callback){
        $data	=	$callback . "(". $data . ")";
    }
    return $data;

• 生成json(不进行转义)

function json_encode_ex($value)
{
	if (version_compare(PHP_VERSION,'5.4.0','<'))
	{
		$str = json_encode($value);
		$str =  preg_replace_callback(

数组处理

• 二维数组转一维数组

    {
        $arrdata = array();
        
        foreach ($data as $key => $value) {

            }
            
        }
        
        return $arrdata;
    }

• 二维数组去重

function arr_duplicate_removal($arr)
    {
        $serializeArrs = array_map('serialize', $arr);
        $uniqueArrs = array_unique($serializeArrs);
        $unserializeArrs = array_map('unserialize', $uniqueArrs);
        return $unserializeArrs;
    }

• 根据指定值获取指定数组

function filter_by_value($array, $index, $value)
    {
        $newarray = array();
        if (is_array($array) && count($array) > 0) {
            foreach (array_keys($array) as $key) {
                $temp[$key] = $array[$key][$index];
                if ($temp[$key] == $value) {
                    $newarray[$key] = $array[$key];
                    foreach ($newarray as $k => $v) {
                        $newarray[$k] = $v;
                    }
                }
            }
        }
        return $newarray;
    }

• 数组切割

/*
$arrF：数组
$user_count：分成几组
$group_num：每组多少个
*/
function array_group($arrF,$user_count,$group_num){
    for($i=0;$i<$user_count;$i++){
        if($i == $user_count-1){
            $arrT[] = array_slice($arrF, $i * $group_num );
        }else{

        }
    }
    return $arrT;
}

• object转数组

function object_array($array) {
    if(is_object($array)) {
        $array = (array)$array;
    }
    if(is_array($array)) {
        foreach($array as $key=>$value) {
            $array[$key] = object_array($value);
        }
    }
    return $array;
}

• 按照键值把数组分类

function group_same_key($arr,$key){
    $new_arr = array();
    foreach($arr as $k=>$v ){
        $new_arr[$v[$key]][] = $v;
    }
    return $new_arr;
}

• 无限极递归分类

function getTree($array, $pid =0, $level = 0)
{
    //声明静态数组,避免递归调用时,多次声明导致数组覆盖
    static $list = [];
 
    foreach ($array as $key => $value) {
        //第一次遍历,找到父节点为根节点的节点 也就是pid=0的节点
        if ($value['pid'] == $pid) {
            //父节点为根节点的节点,级别为0，也就是第一级
            $value['level'] = $level;
            //把数组放到list中
            $list[] = $value;
            //把这个节点从数组中移除,减少后续递归内存消耗
            unset($array[$key]);
            //递归调用
            getTree($array, $value['id'], $level+1);
        }
    }
    return $list;
}

• 根据ip获取地理位置

function get_address($ip){
    $result = json_decode(file_get_contents('http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip='.$ip.'&format=json'));
    $province = isset($result->province) ? $result->province : '';
    $city = isset($result->city) ? $result->city : '';
    return $province.$city;
}

• 根据经纬度计算距离

function getdistance($lng1,$lat1,$lng2,$lat2){//根据经纬度计算距离 单位为公里
    //将角度转为狐度
    $radLat1=deg2rad((float)$lat1);
    $radLat2=deg2rad((float)$lat2);
    $radLng1=deg2rad((float)$lng1);
    $radLng2=deg2rad((float)$lng2);
    $a=$radLat1-$radLat2;//两纬度之差,纬度<90
    $b=$radLng1-$radLng2;//两经度之差纬度<180
    $s=2*asin(sqrt(pow(sin($a/2),2)+cos($radLat1)*cos($radLat2)*pow(sin($b/2),2)))*6378.137;
    return $s;
}

• 获取客户端ip

    {
        $clientip = '';
        if (getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
            $clientip = getenv('HTTP_CLIENT_IP');

            $clientip = getenv('REMOTE_ADDR');
        } elseif (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
            $clientip = $_SERVER['REMOTE_ADDR'];
        }
        preg_match("/[\d\.]{7,15}/", $clientip, $clientipmatches);
        $clientip = $clientipmatches[0] ? $clientipmatches[0] : 'unknown';
        return $clientip;
    }
