How to implement this?

[raysefo]

Hi,

I am new to PHP.So any help would be great. I would like to display a drop down list and a textbox on a page. This dropdown data will be populated from a textbox. What I would like to know is, 

how to:

• parse a file and extact some data from a txt file which is on a server.
• populate this dropdown on the page with the data
• also I would like to display another data on the textbox according to the data selected on the drop down list 

and of couse how to test this script etc.

Best Regards.

No idea what you mean for the last one.

 

I appreciate your new but this applies to life. Go and do your own research and put the effort in yourself and you'll learn a lot more. Come back with a specific problem and we can assist.

 

If you want to know what a specific PHP function does, go to http://php.net/function_name where function_name is any function or even something similar and it'll explain everything.

 

To get you started on your first task:

1. http://php.net/read
2. http://php.net/fopen
3. http://php.net/file_get_contents

Lots of options and ways you can do it. Each one will essentially get you to 1) Open the file, 2) Loop through its contents populating the dropdown.

Hi cpd,

 

Thank you for your reply. Do I need to install something in order to work on php? or just a file editor is OK to write and run it.

 

Best Regards.

If you want to develop locally, which is generally what I do, you'll need to install a web server, PHP and potentially MySQL.

 

Just get the latest releases for each; each can be found at their respective home sites. Alternatively, you can install a package such as WAMP or XAMPP although they often take a while to update so you wont necessarily have the most recent version.

hi cpd,

 

I installed WAMP and wrote some script like below;

<?php
$homepage = file_get_contents('d:\php\test.txt');


$kw = explode("\n", $homepage);
$totalNumRow = 0;
$totalAmount = 0;
 
for($i=0;$i<count($kw);$i++){
	
	
	if(substr($kw[$i], 0, 1) == "5")
	{
		echo $kw[$i];
		// echo "<br>";
		$totalNumRow = $totalNumRow + 1;
		
		$originalstring = $kw[$i];
        $delimiter = ",";
        if(strpos($originalstring,$delimiter) > 0){
                $outarray = explode($delimiter,$originalstring);
                // $variable1 = $outarray[0];
                $amount = $outarray[1];
				echo $amount;
				$totalAmount = $totalAmount + $amount;
        }
		
		echo "<br>";
	}
	
	
}
echo "<br>";
echo "Total records: ".$totalNumRow;
echo "<br>";
echo "Total amount: ".$totalAmount;

?>

It works OK for local file. But the problem is I couldn't manage to get the contents of the file which is on FTP. Is there a way to use file_get_contents on ftp files? 

 

Best Regards.

Yes, you give it an ftp url, like ftp://myusername:mypassword@myserver/dir/file, it should work.

[raysefo]

But how, the port number is different (not 21). How can I add this port number to the url?

[boompa]

ftp://myusername:mypassword@myserver:port/dir/file

 

That should do it

thank you.
