sort($data);

[Matt79]

I have created a page that I place all of the acronyms that I come across.  I have them sorted in alphabetical order using the sort command. It sorts most of them correctly, but there are some that are in incorrect places. I have tried deleting the ones that are in the wrong place, but then new ones appear in their place. If anyone could give me some help that would be great. :-)

Below is the code that I created. I have all of the acronyms contained in the $raw_data variable.

$split=explode("1234567890",$raw_data);
sort($split);
$num=0;
$count=count($split);

while($num < $count)
{
echo $split[$num].'<br/>';
$num++;
}

It would help to get a sample of the $raw_data variable and as well the obvious problem entries (that you claim are in the wrong places).

 

It's hard to predict an error, Without the error..

Ok you can see how it is being sorted here http://snyderit.info/test/acc.php

 

How I have the $raw_data setup is like this:

 

<?php
$raw_data="
customer premises equipment (CPE)1234567890
Service provider (SP)1234567890
virtual circuits (VC)1234567890
Point to Point Tunneling Protocol (PPTP)1234567890
Layer 2 Tunneling Protocol (L2TP)1234567890
IP security (IPsec)1234567890";


$split=explode("1234567890",$raw_data);
sort($split);
$num=0;
$count=count($split);

while($num < $count)
{
echo $split[$num].'<br/>';
$num++;
}
?>

Try using natsort() to sort your array. That should fix it.

[Matt79]

That changes the way it is sorted, but it is much worse using natsort(). It almost appears random.

U do know that uppercase characters proceed lowercase characters?

I think a sample of the sort of what you are seeing and what you expected should be included

[Matt79]

It is included in my previous posts. I tried strtoupper() and it did not change anything.

I want it to be in alphabetical order on the webpage. You can see how it is coming out here:

http://snyderit.info/test/acc.php Please note the DES near the bottom of the page.

 

The script I am using is here:

<?php
$raw_data="
customer premises equipment (CPE)&
Service provider (SP)&
virtual circuits (VC)&
Point to Point Tunneling Protocol (PPTP)&
Layer 2 Tunneling Protocol (L2TP)&
IP security (IPsec)&";


$split=explode("&",$raw_data);
sort($split);
$num=0;
$count=count($split);

while($num < $count)
{
echo $split[$num].'<br/>';
$num++;
}
?>

 

I did remove some of the acronyms before I posted it on the form since there are 188 of them. But the number should not matter.

 

[laffin]

I still don't see the problem, all values are returned by their ascii sorting order, Upcase first, lcase second

My 2cents

$raw_data="a customer premises equipment (CPE)
z Service provider (SP)
y virtual circuits (VC)
A Point to Point Tunneling Protocol (PPTP)
B Layer 2 Tunneling Protocol (L2TP)
6 IP security (IPsec)";

$split=explode("\n",$raw_data);
natcasesort($split);
foreach($split as $str){
echo "$str<br/>";
}

 

6 IP security (IPsec)

a customer premises equipment (CPE)

A Point to Point Tunneling Protocol (PPTP)

B Layer 2 Tunneling Protocol (L2TP)

y virtual circuits (VC)

z Service provider (SP)

It almost appears random.

Almost random, except for the extraneous space characters attached to the 'malfunctioning' values. Get rid of that whitespace and I'd hazard a guess that the problem will go away.

 

[ot]Why are you splitting on 1234567890 rather than something more usual like... a line break?[/ot]

[Matt79]

Thanks MadTechie. I used the code you created and it worked, although I do not quite understand the differences. And I do not know why the a, z, y, A etc, are in your code. I am assuming it is to explain something but do not get it.

a customer premises equipment (CPE)
z Service provider (SP)
y virtual circuits (VC)
A Point to Point Tunneling Protocol (PPTP)
B Layer 2 Tunneling Protocol (L2TP)
6 IP security

 

 

My final script that works thanks to MadTechie:

 

 

<?php

$raw_data="
customer premises equipment (CPE)
Service provider (SP)
virtual circuits (VC)
Point to Point Tunneling Protocol (PPTP)
Layer 2 Tunneling Protocol (L2TP)
IP security (IPsec)
Provider Core (P)
";

$raw_data=strtoupper($raw_data);
$split=explode("\n",$raw_data);
natcasesort($split);
foreach($split as $str){



echo "$str<br/>";
}

?>

 

Thanks guys for all the help

 

[MadTechie]

as a note you don't need to convert it to upper case if your using natcasesort

[Matt79]

ok thanks for the info. I used upper case to make the page layout look better since I did not fallow the correct English writing rules when I created the page  I mixed the lower and upper case.
