[PHP] Variables within variable names
I want to do something along the lines of: $type = basic; $$type_user = jaxn; echo $basic_user; and have the output be jaxn. I have tried everything I can think of, and I have looked in all my books. I know how to: $type = basic; $$type = jaxn; echo $basic; but this won't do what I need. I need the name of the variable to be a variable plus some. I can probably reach my goals using arrays, but I just thought I would ask first. -Jackson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Rather than tying yourself in knots, plus the fact that code using variable variables are mostly harder to debug, you are strongly advised to use arrays. -- Jason Wong - Gremlins Associates - www.gremlins.com.hk Open Source Software Systems Integrators * Web Design Hosting * Internet Intranet Applications Development * /* Your love life will be... interesting. */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Variables in variable names
Hello, I need some help (newbie). I have some variable names with the form: $name_1 $name_2 $name_3 $name_4... I want to access them by doing something like this: $i=0 $name_$i This doesn't work, how do I include another variable in the name of a variable?.

Maybe an array would be more appropriate. e.g. $name[$i] = . . -Stewart -Original Message- From: seriousj [mailto:[EMAIL PROTECTED]] Sent: 09 May 2001 12:09 To: [EMAIL PROTECTED] Subject: [PHP] Variables in variable names Hello, I need some help (newbie).

Re: [PHP] Variables in variable names
The info is stored in the variables intitally by information entered by a user on a webpage, can you have the browser store the info in an array and have it passed by a form post command?

RE: [PHP] Variables in variable names
As an alternative you can use associative arrays $i = 0; $i = 1; $i = 2; $i = 3; $name[$i]; -Original Message- From: seriousj [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 09, 2001 4:09 AM To: [EMAIL PROTECTED] Subject: [PHP] Variables in variable names Hello, I need some help (newbie).

RE: [PHP] Variables in variable names
Yes! Add '[]' to the end of the name. This will inform php that all fields with that name should be put into an array after submission. e.g. FORM... INPUT TYPE=TEXT NAME=name[] INPUT TYPE=TEXT NAME=name[] INPUT TYPE=TEXT NAME=name[] ... After submit php will have created an array called $name with 3 entries. -Stewart -Original Message- From: seriousj [mailto:[EMAIL PROTECTED]] Sent: 09 May 2001 12:20 To: [EMAIL PROTECTED] Subject: Re: [PHP] Variables in variable names The info is stored in the variables intitally by information entered by a user on a webpage, can you have the browser store the info in an array and have it passed by a form post command?

What you´re looking for is variable variables, Try this:
for ($i=0; $i $max_var_count;$i++)
{
$tmp=name_.$i;
$show_var_name_content=$$tmp;
}

RE: Re[2]: [PHP] Variables in variable names
or even try input type=text name=name[] input type=text name=name[] This should AFAIK result in an Array, but I'm not sure if empty fields are put in. You will get the empty fields except for checkboxes. For checkboxes only the checked elements come through so you need values that determine which box was checked. So say you have: input type=checkbox name=box[] value=box_1 input type=checkbox name=box[] value=box_2 checked input type=checkbox name=box[] value=box_3 checked $box[0] == box_2 $box[1] == box_3 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
