Yeah, me too -- here are three routines I use for cutting the right, left
and middle portions of strings. These were keyword routines I used in
FutureBasic -- they seemed to make sense to me so I carried them into php.
?php
// == returns the right-most number of characters from a string
// $string = 123456789
// right($string, 3) returns 123
function right($string, $length)
{
$str = substr($string, -$length, $length);
return $str;
}
// == returns the left-most number of characters from a string
// $string = 123456789
// left($string, 3) returns 789
function left($string, $length)
{
$str = substr($string, 0, $length);
return $str;
}
// == returns the middle number of characters from a string starting
from the left
// $string = 123456789
// mid($string, 3, 4) returns 4567
function mid($string, $left_start, $length)
{
$str = substr($string, $left_start, $length);
return $str;
}
?

Just because I'm a nit-picker, your comments are wrong. Exchange the right

[PHP] need pop-up in progress alert
Greetings, I'm relatively new to PHP and I've been lurking for a while on the list, but now I need a pointer or two. I have an application which has one function that does a lengthy process (installing a piece of software) and I don't want the user to panic thinking nothing is going on. So I want to put up a 'working' box or a progress bar. I have no idea how to do that. I haven't dipped my toes into pear yet. I don't even know how to install or use a pear module. If there is something available that doesn't require pear knowledge so much the better, I guess, but if this is the straw that gets me into pear, so be it. So if someone could point me in the right direction I'd really appreciate it. Thanks, Steve Holmes Purdue University

So if someone could point me in the right direction I'd really appreciate it. Thanks, Steve Holmes Purdue University It might be a better idea to have this installation happen via some other means such as a cron job that isn't influenced by the browser. Then just keep refreshing the page or doing an ajax poll until the job has returned success. Internet connections get dropped, people hit refresh, or whatever and that shouldn't break what is going on (in an ideal world ;)). Thanks for the suggestion, but I'm pretty far along in this project and the idea is that the software install happens on demand. What we are trying to do is get the student/faculty population (tens of thousands of users) to keep their blog/bb/etc. software up to date by giving them a point and click method of updating them (wordpress, phpBB, drupal, etc). We can't *force* them to update, that's against policy, but they keep getting hacked and don't know/care enough to bother doing the update. If you can't figure that out at least put in an ignore_user_abort to prevent the user from hitting stop and messing up the installation process. Just make sure to create some way of knowing that an installation has been started and check a session value/flat file to see if the installation is still going in case the user does request the page again. Once everything is done make sure your script unsets the session variable/flat file to know you can proceed to the next step. Great suggestion. I will have to do this at a minimum. Good luck! Thanks.Steve.

Re: [PHP] Database abstraction?

A free beer (Or beverage of choice)* for everyone who has helped me over the years! I would prefer hard (or soft) cash... :-) Here's my question... I have a program, where I want to take out the field names in a database table and display them... In other words instead of writing: $Query =SELECT First, Last, Middle, Add1 FROM mytable order by $order; I want to write something more like: $Query =SELECT $FIELDNAMES FROM mytable order by $order; So I need to know how to get the field names from the database so that I can populate $FIELDNAMES. I played a little bit and it looks like I might be able to get what I want by doing 2 queries... $QueryFieldNames = DESCRIBE $table; And then some sort of a foreach or maybe a while to populate $FIELDNAMES? Maybe an array so I could do $FIELDNAMES['First'] if I needed to later. then I can use my SELECT $FIELDNAMES FROM $table order by $order query to do my query... Am I on the right path? Way off base? Not even in the ball park? Hopefully it makes sense... Cause it's right on the edge of my knowledge so I'm not totally sure how to ask it right yet :) You could do it adequately with a DESCRIBE, but there might be something that's better.
