【PHP】POSTで画像アップロード

キーボードを新調したので、だいぶご機嫌です。
やっと家と会社で同じのが使えるー♪
キーボード届くから仕事放置でさっさと帰ってきました♪

ちょっと前にiOSとASP .NETのやつ晒しましたが、今日はPHPですねー
今日も手抜きでまたまた昔書いたやつからの抜粋です。
これ書いたの何年前だろう。。。

common.php

<?php
class common {
    public function path_to_url($path, $default_port = 80){
            $document_root_url = $_SERVER['SCRIPT_NAME'];
            $document_root_path = $_SERVER['SCRIPT_FILENAME'];
            while(basename($document_root_url) === basename($document_root_path)){
                $document_root_url = dirname($document_root_url);
                $document_root_path = dirname($document_root_path);
            }
            if($document_root_path === '/')  $document_root_path = '';
            if($document_root_url === '/') $document_root_url = '';

            $protocol = ($_SERVER['HTTPS'] && $_SERVER['HTTPS'] !== 'off')? 'https': 'http';
            $port = ($_SERVER['SERVER_PORT'] && $_SERVER['SERVER_PORT'] != $default_port)? ':'.$_SERVER['SERVER_PORT']: '';
            $document_root_url = $protocol.'://'.$_SERVER['SERVER_NAME'].$port.$document_root_url;

            $absolute_path = realpath($path);
            if(!$absolute_path)
                return false;
            if(substr($absolute_path, -1) !== '/' && substr($path, -1) === '/')
                $absolute_path .= '/';

            $url = str_replace($document_root_path, $document_root_url, $absolute_path);
            if($absolute_path === $url)
                return false;
            return $url;
        }
}

uploadPhoto.php

<?php
    include 'common.php';
    $common = new common();
    
    $uploaddir = '../../photo/';
    $arr = split("_", basename($_FILES['file']['name'][0]));
    $uploadfile = $uploaddir . $arr[0] . "/" .  $arr[1];
    if (move_uploaded_file($_FILES['file']['tmp_name'][0], $uploadfile)) {
        $result = array();
        $result["url"] = $common->path_to_url($uploadfile);
        print(json_encode($result));
    }
    else {
        print(0);
    }
?>
