RE: [PHP] I suck at regular expressions! -- not as bad, now

[Richard S. Crawford]

Thanks to everyone who helped me figure this out.

I foolishly didn't realize that I was using the htmlspecialchars() function 
on the string that I was pulling from the file, but not accounting for that 
in the regexp.  So, what I was getting was:

 

but what I was trying to find was:

 < title >BLAH BLAH BLAH< /title >

It's all good now.

RE: [PHP] I suck at regular expressions!

[Brian Paulson]

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: This is a bad
Title

2. If there are any other < > tags in the title it will fail.

([^<]*)(.*)', $string,
$regs ) )
   {
   $string = $regs[2];
}
}  
 return $regs[1];   
}
} 
?>

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($myFile);
 if (eregi("(.+)",$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?
