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

这应该有效

$file = 'somefile.txt';
file_put_contents($file, $some_var);

您可能希望先序列化变量以使其更具可读性。

但是还有其他几种方法：http://php.net/manual/en/function.file-put-contents.php

Answer 2

不要为此使用 var_dump，像这样使用序列化：

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

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

Answer 3

您可以使用输出缓冲函数来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 4

<?
$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($result))
{
fwrite($rez, $row['DatabaseName']); }

    }

}
ini_set('max_execution_time', 10);
return $link;
    ?>
