Problems when Reading Vars from File

[Anon]

I have variables stored in a text file. They work like varibale name (with out a $) = than the value. I need to read these variables into my php script as the names that they are stored as in the text file with the value that comes after the equal sign. Could somebody give me a quick snipet of code for this problem? Below is an Example of one of the text files:

author_name = Robin Liss

title = Test Article

keywords = keywords, here

summary = summary here

content = content here

notes = notes here

[rodif_bl]

I think this should work
<?
$file = file($filename);
foreach($file as $line)
{
if(trim($line) != "")
{
$pos = strpos($line,"=");
$var = trim(substr($line,0,$pos));
$val = trim(substr($line,$pos+1));
${$var} = $val;
}
}
