[PHP] Arrays of strings from regex
Am working through document to collect pieces that match and then insert
them into an array so they can be used to construct another file.
Looking in my doc for lines like this:
{\*\cs43 \additive \sbasedon10 db_edition;}
{\*\cs44 \additive \sbasedon10 db_editor;}
{\*\cs45 \additive \sbasedon10 db_email;}
Wrote this regex to find them:
^\{\\\*\\?(cs[0-9]{1,3}) (.*)\\[a-z0-9]+ (.*);\}$
Now looking for best method for getting the parts in parenthesis () into an
array so it will contain these values by finding the above three lines:
$matches [0][0][0] = cs43 , \additive \sbasedon10, db_edition
$matches [1][1][1] = cs44 , \additive \sbasedon10, db_editor
$matches [2][2][2] = cs45 , \additive \sbasedon10, db_email
Thanks in advance for any pointers.

[PHP] How to obtain unique XML Elements
Anyone have a simple technique for obtaining a unique list of elements from an XML file? Am looking for something that will identify the first opening tag ie thistag and the single tag anothertag/ so that I get an array of tags that I can print out. Having a bit of trouble with regex to get something to work. Basic idea I had is to open file, read through each line with regex, add matches to array, and then do unique elements of array and write to another file. Is there a better way? -- Regards, Dave -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Record Sorting Using Up and Down Arrows
I'm hoping someone can help me solve this problem. I've almost got something
working. Only problem is I am having some difficulty trying to come up
with a case or condition for the single value (ie. devmodfile value = file 3
in example below) that it won't print any arrows up, up/down, or down. It's
a bit of a puzzler and haven't added anything to the case. I have a print_r
and a print with the variables so that anyone can see what is happening. I
put a small array of test values in so that it can be run. The data will
come from an SQL database but this is enough to test. Once this is working,
I'll attach graphics and actions to the up and down arrows. The script is
below:
Thanks in advance for any help.

?php
$items[] = array(devfunctionid = 1, devmodfile = file1);
$items[] = array(devfunctionid = 2, devmodfile = file1);

[PHP] Record Sorting Using Up and Down Arrows
Hi there. I am trying to write a routine to allow me to sort the contents of
a table by clicking on up or down arrows.
The idea is that top record will have down arrow, bottom record up arrow and
records inbetween both an up arrow and down arrow. Clicking the arrow
causes the record to move up or down one row in the table. The hyperlinks
on the arrows would be used to move the record up or down one by switching
the sort order values in the records ie. you want to move a record one up,
the value of the sort order would be switched with the record above.
I have created a numeric sort field that I initialize with the same value
and the id field in my table. I have my database content in an array that I
want to use. So I want to create the table using an array of rows. I can
get something basic to work if I do a count of my array to get the first and
last value. I do a foreach and test the values in a switch
like:
switch($itemcount) {
case 1:
if ($itemtotal == 1) {
$arrows = '';
} else {
$arrows = $downarrow;
}
break;
case $itemtotal:
if ($itemtotal == 1) {
$arrows = '';
} else {
$arrows = $uparrow;
}
break;
default:
$arrows = $uparrow $downarrow;
break;
}
The problem I am having is to come up with a way to make this work when
there is more than one field to sort on. I have a table with a list of
functions and files. There is a many to one relationship between functions
and files and I want the up and down arrows to work for sorting the
functions in the files in the list. So that if a file has say 4 functions
the first would be down arrow, next two records would have both arrows, last
record for file uparrow, next record down arrow if file is different etc.
Could anyone help by giving me some advice on the best way of getting
something like this to work or have an example to follow. This would be
helpful. I have checked the archives first but could not find anything.
Regards,
DAve

[PHP] Storing script in database??
I am creating an application where it would be useful to write and store script in a field in a MySQL database and create a loop to process the array of the code contained in the field. Conceptually, I think it sounds reasonable but I am uncertain of what kind of process I could use to have the code in the field variable read properly within the loop. Somewhat analogous to an include in HTML. The file would be read as though a single script file though the included material has come from a text field. This would be really useful for me since the code could be modified in the database outside a smaller application without changing the files. Any ideas here on how I might do this from anyone that has attempted anything similar? I have set everything up but just can't figure out how to bring the script text in the field into the file properly. Help much appreciated. -- Dave Pratt [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Example safe use of eval()
I am trying to get code that I have saved as a string in a database to evaluate as code within a larger script with a loop. There are obvious security concerns with allowing users to input code into the field if it is not preprocessed before it is evaluated. The eval function appears to be the ticket with PHP 4 since it will return the results as well. Has anyone got an example of an appropriate preprocessing strategy and/or example of eval() being used this way? Thanks to those that replied to my original post. -- Dave Pratt -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Example safe use of eval()
Thanks, Justin. I am really trying to figure something else out instead of eval. It is really too much of a security hole. I really appreciate the community to bounce ideas. Regards, Dave -- From: Justin French [EMAIL PROTECTED] To: David Pratt [EMAIL PROTECTED], [EMAIL PROTECTED] Subject: Re: [PHP] Example safe use of eval() Date: Thu, Aug 1, 2002, 5:35 PM You can't really do much to make sure the execution of eval is safe, it's more than you have to trust the string that you're about to eval(). So, as long as you and your production team were the only ones who put the code into the strings or tables, and tested the code before hand, then 90% there. I'd suggest also reading all the user-contributed notes at http://php.net/eval too.
