Sorting Arrays

[mark_and_co]

Hey,

I have looked for ages for something so simple, yet I always find complicated answers :mad:

I have an array like 'admin', 'rich', 'alex'
which I have listed in a drop down box, but I want it sorted alphabetically so the results would be:
<select>
<option>admin</option>
<option>alex</option>
<option>rich</option>
</select>

Any simple answers would be greatly appreciated...

Thanks
Mark Baker

Hi,

you can use one of the sort functions:

http://www.php.net/manual/en/ref.array.php

e.g.

$theArray = array('admin', 'rich', 'alex');
sort($theArray);
reset($theArray);

This is my code for testing purposes
$xusermatch = eregi_replace("::", ":', ':", $users);
$xusermatch = eregi_replace("^:", "':", $xusermatch);
$xusermatch = eregi_replace(":$", ":'", $xusermatch);
echo"$xusermatch<br>";
sort($xusermatch);
echo"$xusermatch";

This is the result of the above code:
':admin:', ':rich:', ':alex:'

Warning: Wrong datatype in sort() call in /home/sites/site10/web/item.php on line 97
':admin:', ':rich:', ':alex:'

Any-one else come across this??

Hi,

$xusermatch isn't an array at all. You might need to do the following:

$xusermatch = eregi_replace("::", ":', ':", $users); 
$xusermatch = eregi_replace("^:", "':", $xusermatch); 
$xusermatch = eregi_replace(":$", ":'", $xusermatch); 
echo"$xusermatch<br>"; 
$arrUsermatch = explode(",",$xusermatch);
sort($arrUsermatch); 
echo implode(",",$arrUsermatch);
reset($arrUsermatch);
// now populate the select

Use the array to populate the options of your select.

This is bizarre :eek:

This is what happens with the above code:

'admin', 'rich', 'alex'
'alex', 'rich', 'admin'

The top line is the original order, and the bottom is after it has sorted it, although all its done is turned it backwards

Help please

try this

$arrUsermatch = explode(",",$xusermatch);

print_r($arrUsermatch);

sort($arrUsermatch);
reset($arrUsermatch);

print_r($arrUsermatch);

does it give the same output ??

Hey,

This gives the output:

'admin', 'rich', 'alex'
Array ( [0] => 'admin' [1] => 'rich' [2] => 'alex' ) Array ( [0] => 'alex' [1] => 'rich' [2] => 'admin' )

Hi,

there are three problems:

1) the ":', ':" with the space after the , will have an affect on the sort because the space will be included in the sort
2) same for the '
3) same for the :

This should work:

<?PHP
$users=":alex::blubb::alex2:";
$xusermatch = str_replace("::",",",$users);
$xusermatch = str_replace(":","",$xusermatch);
//$xusermatch = eregi_replace("::", ":,:", $users); 
//$xusermatch = eregi_replace("^:", "", $xusermatch); 
//$xusermatch = eregi_replace(":$", "", $xusermatch); 
//$xusermatch = str_replace(":","",$xusermatch);
echo"$xusermatch<br>"; 
$arrUsermatch = explode(",",$xusermatch);
asort($arrUsermatch); 
reset($arrUsermatch);
echo implode(",",$arrUsermatch);

// now populate the select
?>
