Writing to one variable only in a text file

[deefadog]

Hi, I am trying to save one variable from flash, using php to write the variable to a text file.

The text file has 4 variables per row which is first read into flash, but I only want to save to the last variable.

Here is the text file :

&link0=google&url0=http://www.google.com&count0=0
&link1=yahoo&url1=http://www.yahoo.com&count1=0
&link2=realitydesigns&url2=http://www.realitydesigns.co.uk&count2=0
&link3=actionscript.org&url3=http://www.actionscript.org&count3=0
&link4=kirupa&url4=http://www.kirupa.com&count4=0
&finished=okay&

Here is the php file I am using at the moment (which just over writes the whole lot in the text file!)

<?php
$fd = fopen("counter.txt", "w");
fwrite($fd, "count=$count");
fclose($fd);
?>

I have had a little help from one of the flash forums. one guy reccomends using this code, But I don't know how to implement it!

// set filename
$filename = "test.txt";

// read file into array
$contents = file($filename);

// get array length
$length = sizeof($contents);

// display each line with "for" loop
for($counter=0; $counter<$length; $counter++) {
        for ($tmp=0; $tmp<2; $tmp++) {
        // Use preg_replace here  ???
        }
}

This is part of the code - he reccomended this to finish it - "What you now need to do is use a regular expressions search to find antyhing that says "countX=XXX" where the X's are varialbe, and replace it with the appropriate new count."

If this makes sense, can someone help me out!

Thanks

This is what the above code does,

1. It first loads the content of the page into an array.
2. Reads each line in the page.
3. Since there are three variables in each line, it searches among these variables.
4. Since you need only the last variable containing the text count(number)="something" (for example count0=0), it uses a regular expression to search for a text containing count(number)=XXX where XXX can be anything.

Hope this helps..

Thanks for the response!
Yes what you say is correct! So how do I combine the two bits of php code above to work? I am very new to php.

Thanks

<?php
// set filename
//file from which to read the content
$filename = "test.txt";

// read file into array
$contents = file($filename);

// get array length
$length = sizeof($contents);

// display each line with "for" loop
for($counter=0; $counter<$length; $counter++) {
$arr_matches = split("&",$contents[$counter]);
$arr_length = sizeof($arr_matches);
for ($tmp=0; $tmp<=$arr_length; $tmp++) {
//Check to see if the result contains "count(number)=a number"
$bool = preg_match("/count$counter=\d/",$arr_matches[$tmp],$matches);

		if ($bool) {
			//If a match is found, write the value to a text file
			$fd = fopen("counter.txt", "a+");
			fwrite($fd,$arr_matches[$tmp]);
			fclose($fd);
		}
	}

}
?>

This works.. but I am not very confident about the regular expression syntax used. May be there is a better method to write it.
Hope this helps..

Sorry about the indentation. My intended code does not appear as such in phpbuilder.

Thanks, I used the code you kindly created for me but it's not what I need exactly!

This is what I get when I click the google link using your php code(where the google count variable was set to 10 originally)-

&link0=google&url0=http://www.google.com&count=10&
&link1=yahoo&url1=http://www.yahoo.com&count1=11&
&link2=realitydesigns&url2=http://www.realitydesigns.co.uk&count2=12&
&link3=actionscript.org&url3=http://www.actionscript.org&count3=13&
&link4=kirupa&url4=http://www.kirupa.com&count4=14&
&finished=okay&t=11count=12count=11count=15count=countcount=15count0=10count1=11count2=12count3=13count4=14

I din't want the count variables added to the end of the .txt file, I want it to amend the actual number in the variable that is read -i.e

&link0=google&url0=http://www.google.com&count=5&
&link1=yahoo&url1=http://www.yahoo.com&count1=0&
&link2=realitydesigns&url2=http://www.realitydesigns.co.uk&count2=0&
&link3=actionscript.org&url3=http://www.actionscript.org&count3=0&
&link4=kirupa&url4=http://www.kirupa.com&count4=0&
&finished=okay

The above example is what I want to acheive, this shows that the google link has been pressed 5 times (with the original counts set to 0 in the original file!)

Any Ideas on how to acheive this?

Thanks
