Question

Ok, Ive had a question on this before.

I found out how to delete lines in a txt file using php based on unix time

this is my current code.

<?php
$output = array();
$lines = file('file.txt');
$now = time();

foreach ($lines as $line) {
  list($content, $time) = explode("|", $line);
  if ($time > $now) {
 $output[] = $line;
 }
 }
 $outstring = implode($output);
file_put_contents("file.txt", $outstring);
print time();
?>

What that code does is every entry in the file will have a time next to it in Unix

So

Its set up like this

Content | Unix Time
Content | Unix Time

What I Want to do is Have a PHRASE or WORD In replace of the unix time, that indicates that line needs to stay there.

Is there a snippet or would this be hard?

Any Help would be appreciated.

Answer 1

Adding

$keepStr = "KEEP";

at the top and replacing the foreach loop with:

foreach ($lines as $line) {
    list($content, $value) = explode("|", $line);
    if ($value == $keepStr || $value > time() ) {
       $output[] = $line;
    }
}

would convert

Content1 | KEEP
Content2 | Somevalue
Content3 | Someothervalue
Content4 | KEEP

To

Content1 | KEEP
Content4 | KEEP

You can define the string to keep as whatever you like by changing the value given to $keepStr
