Modify a text file

[christa]

Hi

I have a txt file as this:

[section1]
parameter1:2345|parameter2:goal|parameter3:other

[section2]
parameter1:444|parameter2:val|parameter3:gold

 

Now, i have to edit only one section (section1 or section2 or sectionN...) and edit the values of parameters via form. Then, update the file with new values.

The values are (in the above example): 2345, goal, other....

 

How can I do? please, also post a few of code and example, because i'm a newbie of php.

 

Thanks

someone can help me, please?

Open the file and read it line by line to place it in a new structure:

 

<pre>
<?php
$data = <<<DATA
[section1]
parameter1:2345|parameter2:goal|parameter3:other

[section2]
parameter1:444|parameter2:val|parameter3:gold
DATA;

	$lines = explode("\n", $data);
	$section = 'none';
	foreach ($lines as $line) {
		if (preg_match('/\[([^]]+)\]/', $line, $matches)) {
			$section = $matches[1];
		}
		if (strpos($line, 'parameter') !== FALSE) {
			$array[$section] = preg_split('/parameter\d+:|\|/', $line, -1, PREG_SPLIT_NO_EMPTY);
		}
	}
	print_r($array);

?>
</pre>

thanks. But i've edit your code in order to obtain this (view image):

 

 

I use this code:

<form>
<?php
$filename = "file.txt";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));

$lines = explode("\n", $contents);
	$section = 'none';
	foreach ($lines as $line) {
		if (preg_match('/\[([^]]+)\]/', $line, $matches)) {
			$section = $matches[1];
		echo "<input type='text' name='$section' value=$section><br />";
		}
		if (strpos($line, 'parameter') !== FALSE) {
			$array[$section] = preg_split('/parameter\d+:|\|/', $line, -1, PREG_SPLIT_NO_EMPTY);
			echo "<input type='text' name='$line' value=$array><br />";	
		}

	}

	//print_r($array);

fclose($handle);
?>
</form>
