创建安装程序脚本

我正在尝试使用 fwrite 和表单的组合来创建一个安装程序。这是我的代码：

<?php
$myFile = "db_config.php";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, "$host = " . $_POST['host'] . ";\n $username = " . $_POST['username'] . ";\n     $password = " . $_POST['password'] . ";\n $name = " . $_POST['name']";" ;);
fwrite($fh, 'mysql_connect("{$host}", "{$db_username}", "{$db_password}")\n or     die(mysql_error());\n mysql_select_db("{$db_name}")\n or die(mysql_error()); ?>' ;);
fclose($fh); 
?>

这是错误：

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home2/runetyco/public_html/ballpointradio/new/install_action.php on line 4

I'm trying to create an installer, using a combination of fwrite and forms. Here's my code:

<?php
$myFile = "db_config.php";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, "$host = " . $_POST['host'] . ";\n $username = " . $_POST['username'] . ";\n     $password = " . $_POST['password'] . ";\n $name = " . $_POST['name']";" ;);
fwrite($fh, 'mysql_connect("{$host}", "{$db_username}", "{$db_password}")\n or     die(mysql_error());\n mysql_select_db("{$db_name}")\n or die(mysql_error()); ?>' ;);
fclose($fh); 
?>

Here's the error:

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home2/runetyco/public_html/ballpointradio/new/install_action.php on line 4

您在行尾缺少 .

[...]. $_POST['name'] . [<--] ";" ;)

You are missing a .at the end of the line

[...]. $_POST['name'] . [<--] ";" ;)

相当多的问题 tbh.. 排序

<?php
$myFile = "db_config.php";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, '<?php' . PHP_EOL . '$host = "' . $_POST['host'] . '";' . PHP_EOL . '$username = "' . $_POST['username'] . '";' . PHP_EOL . '$password = "' . $_POST['password'] . '";' . PHP_EOL . '$name = "' . $_POST['name'] . '";' . PHP_EOL );
fwrite($fh, 'mysql_connect($host, $db_username, $db_password)' . PHP_EOL . 'or die(mysql_error());' . PHP_EOL . 'mysql_select_db($db_name) or die(mysql_error());' . PHP_EOL);
fclose($fh);

注意：我不建议这样做，通常最好只写出一个简单的配置文件并保持所有代码静态，但上面回答了您关于所得到的错误的问题。

quite a few problems tbh.. sorted

<?php
$myFile = "db_config.php";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, '<?php' . PHP_EOL . '$host = "' . $_POST['host'] . '";' . PHP_EOL . '$username = "' . $_POST['username'] . '";' . PHP_EOL . '$password = "' . $_POST['password'] . '";' . PHP_EOL . '$name = "' . $_POST['name'] . '";' . PHP_EOL );
fwrite($fh, 'mysql_connect($host, $db_username, $db_password)' . PHP_EOL . 'or die(mysql_error());' . PHP_EOL . 'mysql_select_db($db_name) or die(mysql_error());' . PHP_EOL);
fclose($fh);

note: i wouldn't recommend doing it this way, typically much better to only write out a simple config file and keep all code static, but the above answers your question about the error you get.

问题可能出在 ?> 中。你必须逃避它。另外，您没有将 放在 conf 文件的开头。

为什么你想要它是 php 文件呢？为什么不使用 ini 文件和 parse_ini_file() 或 xml或许？

它给出错误的原因是因为它正在第 4 行查找变量 $host - 如果将双引号更改为单引号，它应该可以解决问题 - 见下文：

<?php
$myFile = "db_config.php";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, '$host = ' . $_POST['host'] . ';\n $username = ' . $_POST['username'] . ';\n $password = ' . $_POST['password'] . ';\n $name = ' . $_POST['name'] . ';\n\n';
fwrite($fh, 'mysql_connect("{$host}", "{$db_username}", "{$db_password}")\n or die(mysql_error());\n mysql_select_db("{$db_name}")\n or die(mysql_error()); ?>' ;);
fclose($fh); 
?>

The reason it's giving an error is because it's looking for the variable $host on line 4 - if you change the double quotes to single it should fix the problem - see below:

<?php
$myFile = "db_config.php";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, '$host = ' . $_POST['host'] . ';\n $username = ' . $_POST['username'] . ';\n $password = ' . $_POST['password'] . ';\n $name = ' . $_POST['name'] . ';\n\n';
fwrite($fh, 'mysql_connect("{$host}", "{$db_username}", "{$db_password}")\n or die(mysql_error());\n mysql_select_db("{$db_name}")\n or die(mysql_error()); ?>' ;);
fclose($fh); 
?>
