[PHP] array_unique() workaround?
I'm working on a script that needs array_unique() but my host is using 4.0.4 and it's broken in that build. Does anyone have a good workaround for this? I can wait for my host to upgrade but if I release this code, it would be better to have the workaround... I just need a good way to check for dups in an array and remove them. I can't get my brain around it...

Re: [PHP] array_unique() workaround? SOLUTION!
Thanks everyone for the ideas,
Here's what I came up with...
I forgot to mention that I needed to preserve the original array's keys.
Here is a replacement I wrote that seems to work. Let me know if you see
errors in it or have improvements.
function my_array_unique($somearray)
{
asort($somearray);
reset($somearray);
$currentarrayvar = current($somearray);
foreach ($somearray as $key=$var)
{
if (next($somearray) != $currentarrayvar)
{
$uniquearray[$key] = $currentarrayvar;
$currentarrayvar = current($somearray);
}
}
reset($uniquearray);
return $uniquearray;
}

[PHP] is_null misses spaces... another solution?
I need to check variables for blank values but it appears that is_null and == return true if there is a space. Any other suggestions?

[PHP] variable gets lost in function problem again...
Sorry all but I really need to figure this out. Here's a recap of my problem: I have an two dimensional array that is returned from code from an included file. I'm assigning parts of the array to variables ( $variable = $array[key][value]; ). This works fine and can be printed until I send it through a function eg. ( ereg_replace( , _, $variable); ). After this, $variable is blank. I don't think it's my code because substituting a text string for the array data (eg. $variable = this is some text;) works just fine. It has something to do with the assigning array data to a variable or perhaps that the data comes from an included file... This could be a bug in PHP? Does this sound familiar to anybody? I can't figure it out! Any help would be much appreciated.

[PHP] passing a multi dimensional associative array...
Pardon me if I've been smoking too much crack but I can't seem to figure
this one out...
How do I pass an argument to a function that contains a value from multi
dimensional associative array?
or... How do I pass an variable as an argument that contains value taken
from an array?
or... Why doesn't the following work? The following (barring any typos)
works for me if the variable $newstring is passed with a value of Some
Random Text (it is returned with spaces replace by underscores) but does
not work when passing the $newstring = $somearray[thing][data] line.
I'm missing something here...
TIA,
Spunk
?php
function RemoveWeirdChars($stringtoreplace)
{
// Removes spaces that could cause problems.
$replacedstring = (ereg_replace( , _, $stringtoreplace));
return $replacedstring;
}
//$newstring = Some Random Text; //This works...
//value comes from an multi-assoc-array
$newstring = $somearray[thing][data]; //doesn't work
//$finishedstring = (ereg_replace( , _, $newstring));
$finishedstring = (RemoveWeirdChars($newstring));
echo $finishedstring;
?

[PHP] argument variable gets lost in function
I'm assigning a variable a value from an associative array. $variable = $array[key][value]; Then passing the $variable to a function. SomeFunction($variable) The variable exists (can be printed) until a built-in function (within the original function) is called. echo $variable; //prints out fine $variable2 = ereg_replace( , _, $variable); echo $variable; //prints out NOTHING... Why is this and how can I get around it?

Re: [PHP] Re: argument variable gets lost in function
hmm...weird! is that the code?
if you show us your real code...maybe you're missing a small detail...
Sorry about the variable names... I can print the variable inside the
function until it goes through ereg_replace. Then it's gone. The code works
fine if I replace the line '$song = $id3info[TIT2][data];' with '$song =
some text string;' Since it's getting the variables value from an included
file's functions that return and assoc. array... it's a bit confusing. I
everything is fine up till the built-in function (inside my function) is
called. Weird is right...
?php
include(getid3.php);
function RemoveSpaces($shittoreplace)
{
// Removes spaces and other characters that could cause problems.
$shittoreplace = ereg_replace( , _, $shittoreplace);
return $shittoreplace;
}
$id3info = (getID3(music.mp3));
$song = $id3info[TIT2][data];
$newsong = RemoveSpaces($song);
echo $newsong;
?

[PHP] Change the filename sent via html header
I've got a script that returns a smil file in a header but I'd like to change the name of the file. The file is sent as blah.php (even though it is a smil file) but I'd like to be able to name it something like blah.sml. Is there a way to do this?

Re: [PHP] Change the filename sent via html header
Okay,
So here's what it looks like now:
header("Content-type: application/x-quicktimeplayer");
header("Content-Disposition: attachment; filename=blah.qtl" );
print(GenerateSMILAlbum($baseURL, $directory, $mp3Array, $albumCover));
This gets me two download dialogs on windows machines if I select "Open in
Place" and does not rename the file to blah.qtl when downloaded on a Mac...
Any suggestions? Thanks for the comments...

Re: [PHP] Getting a header without ANY mime type
This would be part of a test tool I'd like to create in order to test conditions of an application. I want to send a request and ensure that the response has no set type or known length if possible (eg return some media that is undefined and see how the app handles the response). Anyone? Spunk On Thursday 22 March 2001 02:32, you wrote: I've got a situation where I'm interested in returning a header without ANY mime type specified. It looks like the default Mime type is set by the server (plain text)? Or at least when I don't specify the type It's set by PHP (text/html) that's what my server is returning. I'd also like to ensure that there is no content length returned. Is this possible? So you want to give the browser something and make really sure that it has no chance of interpreting it correctly? Perhaps I miss something, but unless your visitors are masochists with too much time on their hands that's a sure way to lose them really quickly. -- 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]
