YESSSS!!! That was it!! Thanks for this information. Now everything works! Happy, happy!!

Thanks, guys! Extract() is not working because the array contains various functions. When the array is extract-ed, it echos back the function calls, not the values that they should derive. For example, after extract(), the values are: function trace_log( $a_log ) { if (is_array($a_log)) { extract($a_log); } echo $file . "<br />"; echo $script . "<br />"; echo $func . "<br />"; echo $line . "<br />"; echo $var_name . "<br />"; echo $var_value . "<br />"; ........ Prints out: Notice: Undefined variable: file in E:\Web\HTDOCS\Learnweb\Register_login\includes\inc_functions.php on line 75 script_name() __FUNCTION__ __LINE__ var_name() var_value() As for serialize(), I'm not clear as to how that would be helpful.

I've spent a lot of time on this, thinking I could figure it out, but I'm royally stuck. I have a "debugging" helper function that I call when I need to know what is happening to a variable. The results of the call are inserted into a table, which I then review for problems. Here is an earlier version of my function call to "trace_log()." It worked fine. trace_log( file_name(__FILE__), script_name(), __FUNCTION__, __LINE__, var_name(), var_value()); Now I want to put the function call parameters into an array. Here is my code: $myarray = array( 'myfile' => 'file_name(__FILE__)', 'script' => 'script_name()', 'func' => '__FUNCTION__', 'line' => '__LINE__', 'var_name' => 'var_name()', 'var_value' => 'var_value()' ); Note that script_name(), var_name(), and var_value() are user defined functions. Now, I am trying to make the parameters in $myarray work within the function, but I have not been successful. Here is how I think the code should begin: function trace_log( $myarray ) { /* Connect to db */ if( is_array( $myarray ) ) { foreach( $myarray as $k => $v ) { ... !!!!! CAN'T GET PAST THIS POINT !!!!! Here is the code I use in the function "trace_log()" to insert the items into a table: $sql = "INSERT INTO reg_log_trace( step, file, script, func, line, var_name, var_value ) VALUES ( 0,'{$file}','{$script}','{$func}', {$line}, '{$var_name}', '{$var_value}' )"; How can I resolve this? Thanks for the help!

Thanks! That's what I was thinking, but I wanted to make sure.

Hi -- I have a debugging function that called like this trace_log( file_name(__FILE__), script_name(), __FUNCTION__, __LINE__, var_name(), var_value()); As I use it many times within a script, is there a way to group the parameters in a variable or constant in order to make the line of code less cumbersome? I know the following won't work, but to give an example of what I mean: $paramList= "file_name(__FILE__), script_name(), __FUNCTION__, __LINE__, var_name(), var_value()"; trace_log( $paramList ); Thanks!

Well, actually, in reality I'm not. See, none of my "variable links" were working -- form, redirection, etc. -- and I couldn't figure it out. So, to illustrate my error on the forum, I just copied and posted a link, which happened to be a reference to the CSS file. I didn't even notice that I had done this. Good catch!

Well, thank you very much! I tried everything BUT that!

This works: form action="http://localhost/mysite/css/screen.css" method="post"> This does not work: <?php $link_1 = "http://localhost/mysite/css/screen.css" ; $link_2 = '"' . "http://localhost/mysite/css/screen.css" .'"' ; ?> <form action=<?php echo $link_1;?> method="post"> <form action=<?php echo $link_2;?> method="post"> Why do neither of the PHP variables work? Thanks!

Every time I see it on the screen, there is an error. So, to me it means Trouble.

Ah, so it stands for token. Thanks for the pointer. I read some more about this (http://en.wikipedia.org/wiki/Lexical_analysis) and it is a pretty complicated subject.

Just curious. Why the term "T_STRING?" Looked it up, but all I could find was that it is a very small pair of underwear.

Thank you, requinix!

Hello -- Other than organizational clarity for the developer, is there a particular advantage (e.g., security, file access speed, etc.) for placing web files (php, css, html, etc.) in various folders and sub-folders vs placing all files in the root directory or in one particular folder? Thanks.

Yes, I meant the variable name. Thanks for the answer.

I did a phpfreaks search for this, but didn't find anything specific. How can I echo out an array name? I have a function to return the array contents (for debugging purposes), and I need it to generate the actual name of the array as well. Thanks!

Thanks for the reply. Yeah, the index.php was in the correct folder, but I finally discovered the problem! In the Apache folder, the "httpd.conf" file did not contain "index.php" in the dir_module (about line number 244): # # DirectoryIndex: sets the file that Apache will serve if a directory # is requested. # <IfModule dir_module> DirectoryIndex index.html index.php (<-- I added) </IfModule> Thanks again!

I've installed Drupal 7.1 on my computer and I'm trying to access it via localhost. However, the site does not load the "index.php" file. Instead, I get the list of files and folders in the working directory with the heading "Index of /drupal71" (drupal71 is the temporary site name). The .htaccess file has the following lines, so I'm confused as to why index.php doesn't load automatically. # Set the default handler. DirectoryIndex index.php index.html index.htm Any suggestions?

Gah! I have it installed, but I didn't know it would do that! Thanks very much for pointing that out!!

I'm working with a downloaded open-source CMS on localhost, and trying to learn. Is there a tool that will list the files (php and otherwise) that are accessed (in order) as the CMS does various normal operations? I want to see the order and the repetition of files that are opened, even if it is something minor. Thanks.

Man, that was fast!! Thanks, fellas!

I have a long PHP script that I didn't write. I'd like to get a simple text list of all the unique variables from the script -- all variables within the script that begin with $, such as $_ADMIN $query $category $user $id $result, etc..... Any ideas how a PHP dabbler can go about this? I did a PHPFreaks search, but didn't find a thread on this. Thank you!

Well, that was simple enough. I thought subqueries were always in the WHERE clause. But I looked it up and you are right. Very helpful. Thanks!

Hi -- I'd like to ask about the SQL statement below, which is something that I didn't know about: the second SELECT, after the FROM phrase. My question is, what is this called? Is it a NESTED SELECT, a SUB-SELECT, an EMBEDED SELECT, or what? I want to read more on this type of statement, but don't know how to classify it. Thanks! SELECT t.* FROM table1 t, ( SELECT id FROM table1 ORDER BY id DESC LIMIT 5,1 ) as x WHERE t.id <= x.id ORDER BY RAND() LIMIT 3

Thank you, Pikachu2000...but doesn't your byline suggest that this is bad?

Well, thank you both. Those simple facts and the code help quite a bit!!
