This is one lousy solution but hey - it's a solution after all; you
can simply remove all  tags containing href before doing the
preg_match_all()-call, something like this below should do it I think.

$src = preg_replace('/]*?href=[^>]*?>/is', '', $src);

VB defaults to pass by reference while PHP defaults to pass by

Hi Tony,

the date() function in PHP does _only_ take UNIX timestamps as an argument
which means that you can not run such a timestamp as the above.

I recommend that you have a look at
http://www.mysql.com/doc/D/a/Date_and_time_functions.html which describes
the built-in functions for date-handling in MySQL. A function to look at
could be DATE_FORMAT().

That depends on the type of license (of course). Some licenes are pretty
hard to understand and you may have to ask a lawyer. However, there is an
easy way: just ask the author of the script you're thinking about including
in your product. He can probably tell you real quick (and free of charge) if

[Jome]

The most important reason in my humble opinion is that users may use the
same password for serveral sites and therefor he or she can feel safe that
his password isn't abused, even if a hacker grabs the database. For
passwords under 128 chars, md5() is a pretty good solution.

This can be more or less resolved, there's almost impossible to fully
protect your site from abuse but you could for example implement something
like max one new password per day. Another way could be to add an additional
detail, like postal code or something which is easy for user to determine
but (probably) not for other people.

This is the way it should be, and it's like that for a reason - if you have
other tables with relations to the ID in the original table, you may cause
some headaches when the holes are filled up by new rows and they become
related to those other tables.

You may find the function mysql_insert_id() useful. If you'd like to count
the number of rows in a table you can SELECT COUNT(*) FROM table;

> 1) Can the next auto_increment value be 'set' by a SQL query

That's done automagically, and it's probably best to leave it that way.

It's possible but not recommended, you can just search through the rows and
see where there's a hole.

If you're using MySQL - I don't know if COUNT() is a part of SQL'92 - you
can use SELECT COUNT(*) FROM table like this:



The two zeros at the end means that mysql_result is to fetch the first row,
the first column of the result.

(Also, it'll be much faster than mysql_num_rows(mysql_query("SELECT * FROM
table"))

[PHP] Speeding up MySQL querys

[Jome]

Hello,

for the moment I'm trying to write searchengine kind-of-thing in PHP using MySQL, 
however MySQL tend to be very slow when searching.

My table is about 100 mb and the query is SELECT * FROM search WHERE search.content 
LIKE '%$keyword%' OR search.filnamn LIKE '%$keyword%'

I've tried setting INDEX but it didn't work out since I'm using BLOB-fields. Is there 
any other way than using INDEX?

Re: [PHP] IMAP and Attachments

[Jome]

I've been working on a webmail for POP3 but I guess the idea is about the same.

To check if a an email has attachments you use the function imap_fetchstructure() and 
then you can do something like this:

$struc = imap_fetchstructure();
count($struc->parts);
if ($no_of_parts > 0) {
echo "the message has attachments.";
}

This is my way of doing it, the 'bad' thing with this kind of code is that it also 
includes HTML-messages. This can be prevented with some extra code though.

For downloading you use the same kind of thing, I guess it slightly more advanced and 
you have to do some decoding of the message.

Re: [PHP] Sending alots of mail

[Jome]

I have done this, and it's not a bad idea as long as you aren't sending spam.

It's rather easy to do this, just do a mysql_query() from the database where you 
select the subscribers field and then do a while which sends out emails via the 
mail()-function.

You may experience problem with max execution time if you're using a bad mailserver 
but it can be solved by simply extending the max execution time in php.ini or in just 
the specific script.
