他用PHP函数在服务器上创建文件

Question

How to Make this script rewrite content in Output Files , Now it's only merge a new content with a previous content (in the same files)

Here is my code

<?php
    $filename = 'test.php';
    $somecontent = "<?php $jdst_xx = 'HELLO'; ?>
";

    // Let's make sure the file exists and is writable first.
    if (is_writable($filename)) {

        // In our example we're opening $filename in append mode.
        // The file pointer is at the bottom of the file hence
        // that's where $somecontent will go when we fwrite() it.
        if (!$handle = fopen($filename, 'a')) {
             echo "Cannot open file ($filename)";
             exit;
        }

        // Write $somecontent to our opened file.
        if (fwrite($handle, $somecontent) === FALSE) {
            echo "Cannot write to file ($filename)";
            exit;
        }

        echo "Success, wrote ($somecontent) to file ($filename)";

        fclose($handle);

    } else {
        echo "The file $filename is not writable";
    }
    ?>

Answer 1

try to change your

if (!$handle = fopen($filename, 'a')) { // open in append mode

to

if (!$handle = fopen($filename, 'w')) {  // open in write mode
