将var_dump保存到文本文件中 [英] save var_dump into text file

问题描述

我有用于SQL查询的php代码

I have the php code for sql query

<?
$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

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" }

推荐答案

您可以使用输出缓冲功能来捕获输出并将其写入文件.

You can use the output buffering functions to capture output and write it to a file.

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