php将数组或对象原样写入或保存到文件有三种方法可以实现

2020-5-8 aslronx

来源：https://www.cnblogs.com/ryanzheng/p/9086115.html

第一种方法是使用serialize，

第二种方法是使用print_r，

第三种方法是使用var_export，

本文章向大家介绍这三种方法是如何将数组写入到文件的，需要的朋友可以参考一下。

第一：serialize方法

使用 serialize 将数组序列化，存储在文件中；调用时，再使用 unserialize 还原。

$file = './cache/phone.php';
$array = array(
    'color' => array('blue', 'red', 'green'),
    'size' => array('small', 'medium', 'large')
);
//缓存
if (false !== fopen($file, 'w+')) {
    file_put_contents($file, serialize($array));
    //写入缓存
}
//读出缓存
$handle = fopen($file, 'r');
$cacheArray = unserialize(fread($handle, filesize($file)));

第二：print_r方法

用print_r 将数组打印到txt文件中。

$b = array('m' => 'monkey',
    'foo' => 'bar',
    'x' => array('x', 'y', 'z'));
$results = print_r($b, true);
file_put_contents('filename.txt', print_r($b, true));

第三：var_export方法

用var_export 直接将数组以完整数组的形式存储到文件中。

$file = './cache/phone.php';
$array = array(
    'color' => array('blue', 'red', 'green'),
    'size' => array('small', 'medium', 'large')
);
//缓存
$text = '<?php $rows=' . var_export($array, true) . ';';
if (false !== fopen($file, 'w+')) {
    file_put_contents($file, $text);
} else {
    echo '创建失败';
}

将对象完整的存储并追加到文件末尾

$file = "notic_" . date("Ymd") . ".log";
$ct = date("Y-m-d H:i:s", time());

file_put_contents($file, var_export($object,true)."\r\n", FILE_APPEND);

ps: 正常情况下输出到网页的数组会有限制，

php var_dump函数对数组进行打印时，对多维数组中数组的层级越多越深层，子数组会不显示，只用省略号代替。这样一来不便于程序的调试。

php的var_dump函数是php模块中xdebug模块所支持的，所以接下来我们需要配置这个xdebug即可。

修改 php.ini

;设置显示最大的子节点数
xdebug.var_display_max_children=128 ;设置显示最大的字节数
xdebug.var_display_max_data=512 ;设置显示最大得层级（深度）
xdebug.var_display_max_depth=15

然后重启 php 服务

systemctl reload php-fpm nginx

        $content = curl_exec($ch);
        curl_close($ch);
    } else {
        ob_start();
        readfile($url);
        $content = ob_get_contents();
        ob_end_clean();
    }
    $size = strlen($content);
    //文件大小
    $fp2 = @fopen($save_dir . $filename, 'a');
    fwrite($fp2, $content);
    fclose($fp2);
    unset($content, $url);
    return array(
        'file_name' => $filename,
        'save_path' => $save_dir . $filename
    );
}
$url = "http://www.baidu.com/img/baidu_jgylogo3.gif";
$save_dir = "down/";
$filename = "test.gif";
$res = getFile($url, $save_dir, $filename, 1);
var_dump($res);
