PHPExcel 出现open_basedir restriction in effect的解决办法

找到函数 sys_get_temp_dir。替换函数内容为一下内容

public static function sys_get_temp_dir()
	 {
		// use upload-directory when defined to make it running on
		// environments having very restricted open_basedir configs
		if (ini_get('upload_tmp_dir')!==false) {
			if($temp = ini_get('upload_tmp_dir')) {
				if (file_exists($temp)) { 
					return realpath($temp); 
				}
			}
		}
 
		// sys_get_temp_dir is only available since PHP 5.2.1
		 // http://php.net/manual/en/function.sys-get-temp-dir.php#94119
 
		if ( !function_exists('sys_get_temp_dir')) {
			if ($temp = getenv('TMP') ) {
				if (file_exists($temp)) {return realpath($temp);}
				if (($temp!='') && file_exists($temp)) {return realpath($temp);}
			 }
			 if ($temp = getenv('TEMP') ) {
				if (file_exists($temp)) {return realpath($temp);}
			 }
		}
	}
