は、以下のコードのようなハンドラを適用します。どこに問題があるかを試してみてください。

<?php 
$filename = 'test.txt'; 
$somecontent = "Add this to the file\n"; 

// 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"; 
} 
?>
