Been Using this Function for some time and works real well with two
exceptions
1. if the title line has a CR in it it will no get the title
Example: <title>This is a bad
Title</title>
2. If there are any other < > tags in the title it will fail.
<?
function title($file)
{
$loc = "/path/to/file";
if(is_file("$loc/$file"))
{
$open=fopen("$loc/$file","r");
while(!feof($open))
{
$line=fgets($open,1000); // this is set large due to some of
the long title we have
$string = $line;
while ( eregi( '<headline>([^<]*)</headline>(.*)', $string,
$regs ) )
{
$string = $regs[2];
}
}
return $regs[1];
}
}
?>

Subject: [PHP] I suck at regular expressions!
I am trying to get the title of an html file... you know, the string
between the < title > and < /title > tags...
Here is the function I've got so far:
function fileTitle($fileName) {
$myFile = fopen($fileName, "r");
$myText="";
while (!feof($myFile)) {
$myText .= fgets($myFile,255);
}
fclose($myFile);
if (eregi("<TITLE>(.+)</TITLE>",$myText,$theTitle)) return
$theTitle[0];
else return "(No Title)";
}
The trouble is, it always returns "(No Title)", regardless of whether
the
file has a title defined in the header or not.
I suspect I'm doing something fundamentally wrong. Can anyone set me
straight?
Sliante,
