[PHP] Re: Creating file & file permissions
Hi All
I'm trying to create temp files with my script.
I'm using the line
$fp = fopen("users/temp123", "w+");
which produces the follow error
Warning: fopen("users/temp123", "w+") - Permission denied in
/webSite/signup.php on line 71
How do I get around this??
Make sure the 'users' directory is chmod'd correctly (777) so your PHP
script has the ability (ie: permissions) to write/create files inside.

[PHP] Re: dynamic arraynames
Please can someone offer an idea.
I am trying to generate arrays to hold inputs to columns. Column
titles are input to a table as needed. They are read by the program
and placed across the page. Then an array goes under each column name
to collect the inputs to the various rows. Everything works except to
dynamically change the name of the array.
while($foo=mysql_fetch_array($mysql_result)){
print "";}
I can't see how to change the name of the array on the fly.
Or maybe their is a better way?
Still trying to grasp what you're doing, but I think what you need falls
under the category of variable variables.
For instance:
${"this"} = "some value";
...is the same as...
$this = "some value";
...which is the same as...
$text = "this";
${$text} = "some value";
So dynamic arrays could be generated simply by...
${$name} = array(".

Might help too...

[PHP] Re: Newbie: element index array
If I declared an element indexed array and put some values into it:
$a['element1'] = array('btime' => '19D', 'etime' => '22D', 'dayname' => 4);
$a['element2'] = array('btime' => '12D', 'etime' => '20D', 'dayname' => 2);
$a['element3'] = array('btime' => '15D', 'etime' => '17D', 'dayname' => 3);
I would like to ask that how can I completely delete the $a['element2'] in
the array? That's mean I will get 'false' in 'isset($a['element2']) after
the delete process is taken place.
Thanks for your help.
Use unset()

Re: [PHP] does //commenting reduce performance?
I have always had the opinion that the more comments you put into php scripts, the slower they will run because there is more data to be read... Can someone tell me if there is any truth in this or whether commenting has absolutely 'no' impact on the performance of a script? The comments are ignored, except the characters that initiate the actual comment. //some comment $somevar="va"; "some comment" wouldn't even be looked at. PHP sees the //, and goes to the next line. I suppose on a large scale this could reduce performance, but the performance that is lost in standard applications is minuscule. One thing you might want to avoid is using comments inside loops. -- Kyle Gibson admin(at)frozenonline.com http://www.frozenonline.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: deleting a record.
".$myrow['id']." ".$myrow['company']."";
printf("(DELETE)",
$PHP_SELF, $myrow["id"]);
}?>
There's an easier way to display this. It should make your life
easier...made mine.
Take a look:
// get the list of resellers from the db
$res = mysql_query("SELECT * FROM resellers ORDER BY id");
// print all records in the DB
while ($myrow = mysql_fetch_array($res)): ?>
(DELETE)
now when I click on delete it just reloads the page and doesn't delete the
record. I have this code before anything else on the page to handle the
delete...
if($delete){
$res= mysql_query("DELETE FROM resellers WHERE id=$id");
header("Location: admin2.php?op=resellers");
}
What you should do here is check to see if $res is failing, simply by
doing the following:
if(!$res) echo "error";
Then, place an 'exit;' after the header(...) command to see if the
$delete variable is actually being passed.

Re: [PHP] Passing arguments to the same script
Thanks for responding. I think I'm still doing something wrong. Take a

}
elseif(isset($_GET['samples'])) {
echo "Samples link content will go here";
}
elseif(isset($_GET['rates'])) {
echo "Rates link content will be here";
}
elseif(isset($_GET['contact'])) {
echo "Contact information will go here.";
} else {
echo "Main content goes here.";
}
The only thing that EVER gets displayed is the final else. (Main content
goes here.) What am I doing wrong? Once again, the links are in this
format:
This string merely filles the $HTTP_SERVER_VARS["QUERY_STRING"] variable.
So you should rather check to see if $HTTP_SERVER_VARS["QUERY_STRING"]
equals 'questions', 'samples', etc...
$_GET['var'] requires that the link look like this:
You could then call $_GET['page'], which would contain the value samples.

I believe the problem occurs here. $p becomes a reference to the

This *should* work:
function createParent()
{
//the lack of the '()' might have caused other problems
return &new Parent();

$p = createParent();
That way $p equals the value that is returned by the function
createParent, which is a reference to the Parent object.

[PHP] SSH
I am curious as to how I would go about executing SSH command line operations through PHP. Say for instance the command "ftpwho", which would return a list of users connected to a FTP server, along with what they are doing, etc. I've tried to open a socket to my SSH server, along with the functions system(), shell_exec(), and exec().

That is how I know of WREFERER. Do you know what it is? If you want, you can look at my phpinfo page here: http://php.plaguenet.com/MyAdmin/phpinfo.php.

My firewall prevented me from seeing the variable in action. Ignore this. -Kyle -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: HTML to mysql - from msql to html
You entered data into a text area field that was entered into a mysql
row. Then you tried to print it out.
Try this:
$content = str_replace("\n","",$row["row_name"]);
echo $content;

I've tried this,
$cmd = `ftpwho`;
echo $cmd;
and/or
$cmd = shell_exec("ftpwho");
echo $cmd;
But I get this error:
Warning: Cannot execute using backquotes in safe mode in test.php on line 2

In the php.ini file, safe mode is off.
