如何从web界面将文本附加到PHP文件中？

我有一个文本文件

name.txt（包含）

这是代码：

<?php

// set file to read
$filename = “name.txt”;
$newdata = $_POST['newd'];

if ($newdata != '') {
    // open file 
    $fw = fopen($filename, 'w') or die('Could not open file!');

    // write to file
    // added stripslashes to $newdata

    $fb = fwrite($fw,stripslashes($newdata)) or die('Could not write to file');
    // close file
    fclose($fw);
}

// print file contents

echo "<h3>DEV: Add/Remove Configurations</h3>
    <form action='$_SERVER[php_self]' method= 'post' >
    <textarea name='newd' cols='90%' rows='50'> $data </textarea>
    <input type='submit' value='Change'>
    </form>";
?>

请告知！Thx

您打开的文件不正确，如果要将数据追加到文件末尾，请使用

a+

参数

a+

=追加，如果文件不存在，则创建它

<?php

// set file to read
$filename = “name.txt”;
$newdata = $_POST['newd'];

if ($newdata != '') {
    // open file 
    //$fw = fopen($filename, 'w') or die('Could not open file!');
    $fw = fopen($filename, 'a+') or die('Could not open file!');

    // write to file
    // added stripslashes to $newdata

    $fb = fwrite($fw,stripslashes($newdata)) or die('Could not write to file');
    // close file
    fclose($fw);
}

// print file contents

echo "<h3>DEV: Add/Remove Configurations</h3>
    <form action='$_SERVER[php_self]' method= 'post' >
    <textarea name='newd' cols='90%' rows='50'> $data </textarea>
    <input type='submit' value='Change'>
    </form>";
?>

从你的双引号看，似乎是在使用Word或类似的东西来编写代码。给自己找一个像样的自由文本编辑器，比如
notepad++
  Sean:”allen”
  Peter:”fletcher”
  Jake:”wilson”
  Tommy: “Johnson”)

<?php

// set file to read
$filename = “name.txt”;
$newdata = $_POST['newd'];

if ($newdata != '') {
    // open file 
    //$fw = fopen($filename, 'w') or die('Could not open file!');
    $fw = fopen($filename, 'a+') or die('Could not open file!');

    // write to file
    // added stripslashes to $newdata

    $fb = fwrite($fw,stripslashes($newdata)) or die('Could not write to file');
    // close file
    fclose($fw);
}

// print file contents

echo "<h3>DEV: Add/Remove Configurations</h3>
    <form action='$_SERVER[php_self]' method= 'post' >
    <textarea name='newd' cols='90%' rows='50'> $data </textarea>
    <input type='submit' value='Change'>
    </form>";
?>
