Explode based on "\n"

[fufaso]

I'm hoping someone can shed a bit of light on what is wrong with my code here as I've been playing around with it for a few hours and haven't solved the riddle!

 

$fp=@fopen("test.txt","r") or die ("Cannot open the file, not there!");

while ($line=@fgets($fp, 1024)) {
$list = explode("\n", trim($line)); 
sort($list);
$count = count($list);
for($i=0;$i<$count;$i++){
print "<option>".$list[$i];
}}
@fclose($fp) or die ("Still open!!!");
?>
</select>
</form>

 

my text file looks like this

Canada
Brazil
US
Mexico

 

I'm trying to explode that text file into an array, sort it, and populate the options box. This isn't working, and all the different iterations I've tried are yielding no success either...  :-\

Your code is working just fine for me. I only modified the print statement to close the option field.

 

Output:

<select>
    <option>Canada</option>
    <option>Brazil</option>
    <option>US</option>
    <option>Mexico</option>
</select>

really? it's working? sorting the countries by name and inserting them??

i'm getting a blank space as my first dropdown option, then canada, then another blank space, then brazil and so on until the end of the file.

You could use file() if you wanted.

 

<select>
<?php
$file = file('t1.txt');
sort($file);
foreach($file AS $country){
    echo "<option>".$country."</option>\n";
}
?>
</select>

that worked wonderfully, but for some reason when i plug that php code into the <select> tags, the second form disappears?

 

nvm, i just removed the close file and it worked...

ok, so I have it all working now, but I have one last question.

when I insert a new value and append it to my file, I am submitting back to the test.php page, however my new value is not being populated in the dropdown when i do that. I have to hit the reload button on the web browser to have it show up. Is there a way to have it repopulate when I hit submit??
