在PHP應(yīng)用中,經(jīng)常會用到將指定的內(nèi)容直接存儲到文件中[少而快],而非數(shù)據(jù)庫中[麻煩慢],比如我們微信開發(fā)經(jīng)常讀取的access_token, 程序員使用的一些基本配置文件等,這里給大家介紹下具體的使用方法
//將json格式的字符串存到指定的php文件中 function set_php_file($filename, $content) { $fp = fopen($filename, "w"); fwrite($fp, "<?php exit();?>" . $content); fclose($fp); } //獲取php文件的內(nèi)容 function get_php_file($filename) { return trim(substr(file_get_contents($filename), 15)); } $filename = "./a.php"; $data = ["names"=>"莊子","age"=>18,"hobby"=>"NBA,足球,乒乓,象棋"]; $content = json_encode($data); set_php_file($filename,$content); $rs = json_decode(get_php_file($filename)); echo $rs->names;
