[PHP] array variables with or without quotes
I recently encountered a situation where I had to retrieve data from a MYSQL
database table with a field named "include". My code looked like this:
$content_result = mysql_query('SELECT * FROM calander') or
die(mysql_error());
$content_row = mysql_fetch_array($content_result);
if ($content_row[include])
{go do something;}
When I tried to run this, PHP treated the word -include- as a control
structure rather than an index name. Understandable. So, I put it in single
quotes ('include') to see what would happen and it works fine. But I don't
understand why!
What is the difference between $content_row [include] and
$content_row['include']? I have been unable to resolve this question in the
php manual, I need enlightenment.

Chuck, you are the man! I decided to reread the manual word for word but
have only gotten through Strings as of last night. Thanks for zeroing me in
on the right spot.

Re: [PHP] Phone number validation
""Paul Goepfert"" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] I didn't realize that those were single quotes. I printed out the email message and it looked like one set of double quotes for the second parameter rather the two single quotes. Is it possible for anyone to tell me what php method is used to grab the first charater of a string? And onece I have it what method removes the characted or number? I know this seems trivial but I am still new to php and I don't have a good understanding of the language yet. The more I do the better I'll get. Thanks Paul check out this page of the php manual for a few ideas.
