POST does not work

[phpllama]

cash.php

<?php
$file = file('./file.txt');
$line = $file[array_rand ($file)];
$split = explode(",", $line);
$name = $split[0];
$number = $split[1];
if($_POST['numbers'] == $number){
    echo 'True';
} else {
    echo 'False';
}
?>
<form action="cash.php" method="post">
<?php echo "$name: "; ?><input name="numbers" type="text" /><input 

type="submit" />
</form>

 

file.txt

banana,1
orange,2
grape,3
lemon,4

 

The PHP reads the text file, chooses a random line, splits it up by comma into $name and $number. The form basically checks $number is correct. But it does not work correctly and comes up false.

find out exactly what isnt working

 

before the IF statement,

 

echo "number = ".$number."<br /> post numbers = ". $_POST['numbers'];

This line

$file = file('./file.txt');

Needs to be

$file = array_map('trim', file('./file.txt'));

 

Now your code will work as you expected.
