how do I write to the end of the first line of a flat text file

[husslela03]

Hello,

 

I would like to write to the end of the first line of flat text file.

 

The text I would like to append is text that is entered from a text box on a form.

 

How would i do this?

 

I read the flat file into an array, but I wasn't sure if I need to do a loop to write to the first line or?

 

Please help...

Yes you can use the file function to grab the contents of each line into an array. But you wouldn't need to use a loop to append some text to the first line. You'd use $var[0] eg

$contents = file('filename.txt');

// append something to Line 1
$content[0] .= " whatever you want to put here";

 

Now to save the changes you'd use

// convert the array to a string using implode()
$text = implode($content);

// rewrite the file
file_put_contents("filename.txt", $text);

I'm getting a fatal error regarding file_put_contents.

 

Fatal error: Call to undefined function: file_put_contents() in C:\xampp\htdocs\SASI\add_assignment.php on line 56

What version of PHP are you using? run phpversion or phpinfo to find out.

file_put_contents is only available in PHP 5+, instead you'll have to use fopen, fwrite and fclose.

 

$fp = fopen('somefile.txt', 'w');
fwrite($fp, $text);
fclose($fp);

or upgrade to the latest version, which would be the more ideal solution.  keep with the times.
