writing / reading from a file

Anon

The following code works to an extent...it doesn't read the title from title.txt until the 2nd time the page is loaded. Any idea why?

<?
$filename = "title.txt";
$fd = fopen ($filename, "r");
$title = fread ($fd, filesize ($filename));
echo "<TITLE>$title</TITLE>";
echo "</HEAD>";
echo "<BODY bgcolor=\"#FFFFFF\" link=\"#000000\" vlink=\"#000000\" alink=\"#000000\">";
echo "<table border=\"0\" align=\"center\" cellspacing=\"3\" cellpadding=\"3\" width=\"600\">";
echo "<tr>";
echo "<th colspan=\"2\" width=\"100%\" bgcolor=\"#FFCC00\">";
echo " <font size=\"6\" color=\"blue\" face=\"arial, helvetica\">$title</font> &nbsp";
echo "</th>";
echo "</tr>";
echo "<tr>";
echo "<td colspan=\"2\"><hr></td>";
echo "</tr>";
echo "<tr></table>";
echo "<FORM ACTION=\"$PHP_SELF\" METHOD=\"POST\">";
echo "<INPUT TYPE=TEXT NAME=titlename SIZE=50>";
echo "<INPUT TYPE=SUBMIT NAME=\"SUBMIT\" VALUE=\"Change Title\" METHOD=\"POST\">";
echo "</FORM></BODY>";

function WriteToFile ($titlename)
{
$plain=htmlspecialchars($titlename,ENT_NOQUOTES);
$TheFile = "title.txt";
$Open = fopen ($TheFile, "w+");
if ($Open){

            fwrite ($Open, "$plain");
            fclose ($Open);
            $Worked = True;
    } else {
            $Worked = False;
    }
    return $Worked;

}

if($titlename)
{
$CallFunction = WriteToFile ($titlename);
}
?>

vsego

Since file is first being read and then changed, this behavior makes sense. :-)

Use this:

<?php
function WriteToFile($titlename) {
...
}

if (isset($titlename))
$CallFunction = WriteToFile ($titlename);

$fd = fopen ("title.txt", "r");
$title = fread ($fd, filesize ($filename));
echo "<TITLE>$title</TITLE>";
...
?>

Btw, why all these echoes? It's easier to close PHP block and write plain html:
<TITLE><?= $title ?></TITLE>
</HEAD>
<BODY bgcolor="#FFFFFF" link="#000000" vlink="#000000" alink="#000000">
