Grab Random Line from .txt then delet the line

Question

So here is basically what i want to do, say var.txt is = :

bar
foo
smooth
green

then say i run a code like this in php to grab a random line:

$mineloc = file("var.txt");
$mineacc = $mineloc[array_rand($mineloc)];

what would i do then to remove the line that shows up in $mineacc from var.txt which will result in var.txt being this if the word smooth was generated:

bar
foo
green

Does this answer your question? [how to delete a single line in a txt file with php](https://stackoverflow.com/questions/48490252/how-to-delete-a-single-line-in-a-txt-file-with-php) — domsson, Jan 19 '20 at 09:07
Naive approach: read every line from file, then overwrite the file with the lines you read, minus the one that you picked. See the possible duplicate question for more details. — domsson, Jan 19 '20 at 09:09

I hope this will solve your problem....

$content = file_get_contents('var.txt');
$contentArray = explode('
',$content);

unset($contentArray[rand(0, count($contentArray))]);

file_put_contents('var.txt', implode('
',array_values($contentArray)));

have you executed it ? – Ronak Dhoot Jan 19 '20 at 09:43
doesnt work, when i try to echo out $contentArray it just echos array and then when i check var.txt it is empty. – BlazeNoxxer Jan 19 '20 at 10:00
idk then do you have any other method that might work with the line like – BlazeNoxxer Jan 19 '20 at 10:21
$mineacc = $mineloc[array_rand($mineloc)]; – BlazeNoxxer Jan 19 '20 at 10:21
