将var_dump保存到文本文件中

Question

我有sql查询的PHP代码

<?
$server = "127.0.0.1";
$username = "root";
$password = "1";

$link= connecttodb($server,$username,$password);

function connecttodb($server,$username,$password)
{

    $rez=fopen("test.txt","ab");
    if ($link=mysql_connect ("$server","$username","$password",TRUE))
    {
        fwrite($rez,"".$server." \r\n");
	    echo "Connected successfully to >> " .$server ;
		
		$result = mysql_query('SHOW DATABASES');
        echo "<br>";
        while ($row = mysql_fetch_array($result))
        {
            var_dump ($row); }
	    }
    }
    ini_set('max_execution_time', 10);
    return $link;
?>

此代码在浏览器上打印我的数据库名称如何将数据库名称保存到文本文件中

Connected successfully to >> 127.0.0.1
array(2) { [0]=> string(18) "information_schema" ["Database"]=> string(18) "information_schema" } array(2) { [0]=> string(2) "db" ["Database"]=> string(2) "db" } array(2) { [0]=> string(5) "mysql" ["Database"]=> string(5) "mysql" } array(2) { [0]=> string(10) "phpmyadmin" ["Database"]=> string(10) "phpmyadmin" } array(2) { [0]=> string(4) "test" ["Database"]=> string(4) "test" }

Answer 1

您可以使用输出缓冲功能捕获输出并将其写入文件.

ob_flush();
ob_start();
while ($row = mysql_fetch_assoc($result)) {
    var_dump($row);
}
file_put_contents("dump.txt", ob_get_flush());

Answer 2

不要为此使用var_dump,使用serialize如下:

<?php
$fp = fopen('vardump.txt', 'w');
fwrite($fp, serialize($myobj));
fclose($fp);
?>

要恢复它,可以使用unserialize($ filecontents); 通过从文件中读回来.
