Hello!,
I work in another language mostly and often develop while displaying
variables (post,get,and defined) and their values at the bottom of the
page or in specific places. So, I thought I'd forward my PHP version as
an effort of good Karma to the list perhaps! ;-)
Below is 2 simple functions that are helpful for troubleshooting while
developing. Just place this code into a .php file and require it at the
top of any PHP page. Then, at the bottom of the page, or in a specific
(more pertinent) location, call the functions with something like this:
------------
<?PHP
//troubleshooting code
print '<br /><b>Testing:</b><p>';
print htmlentities(list_formvars());
print htmlentities(list_vars(get_defined_vars()));
print '</p>';
?>
-------------
Optionally, you can call only specific naming conventions of your
variables (if you use them).. ie:
print htmlentities(list_vars(get_defined_vars(),'t_'));
The above will display all defined vars such as:
t_name=<value>
t_city=<value>
t_address=<value>
etc..
Code:
-----------------------------------
/*
FUNCTION NAME: list_formvars
INPUT: optional <begins with> var
OUTPUT: <Name> = <Value> <br />
<Name> = <Value> <br />
USE: For troubleshooting code
Example Use:
list_formvars();
list_formvars('f_a');
*/function list_formvars($pmatch = null) {
print "<br /><b>'get' Vars:</b><br />";
foreach ($_GET as $key => $value) {
if (isset($pmatch)) {
if (substr($key,0,strlen($pmatch)) == $pmatch) {
print "$key = $value<br />";
}
} else {
print "$key = $value<br />";
}
}
print "<br /><b>'post' Vars:</b><br />";
foreach ($_POST as $key => $value) {
if (isset($pmatch)) {
if (substr($key,0,strlen($pmatch)) == $pmatch) {
print "$key = $value<br />";
}
} else {
print "$key = $value<br />";
}
}
}/*
FUNCTION NAME: list_vars
INPUT: get_defined_vars(),<begins with> match
OUTPUT: <Name> = <Value> <br />
<Name> = <Value> <br />
USE: For troubleshooting code
Example Use:
list_vars(get_defined_vars());
list_vars(get_defined_vars(),'t_');
*/function list_vars($a_vars,$pmatch = null) {
print "<br /><b>'defined' Vars:</b><br />";
foreach ($a_vars as $key => $value) {
if (isset($pmatch)) {
if (substr($key,0,strlen($pmatch)) == $pmatch) {
print "$key = $value<br />";
}
} else {
print "$key = $value<br />";
}
}
}
------------------------------------------------

Donovan
P.S. Always open to good criticism if you peeps see something that can
be written better.. this is about my 3rd PHP project only... so, still
heavily learning ;-)
