array emptying...

[Shai-Hulud]

I have got this script:

<?php
$filename = 'test.txt';
$handle=fopen ('board/' . $filename, "r");
$contents=explode("'", fread ($handle, filesize ('board/' . $filename)));
?>

say I want to remove $content[3] from the array and rwrite the file, what would be the best way to do this? is there maybe a special command for this?

thanks 🙂

i'd just use [man]file_put_contents[/man] to overwrite the old data with the amended data...

I actually ment how I can remove the contents[3] from the array and that the rest of the array will move to the empty place

there isn't a function that will do it but you could write some code to handle it, basically a for loop that starts out on the index you want to erase (3) and move the next index into the previous one until you reach the end of the array, and then use array_pop to get rid of the last element.

You could look into [man]array_splice/man, actually.

I found it!

unsset($contents[3])

and the array automatically moves.

all I need now is the command to delete the file... 😃
