Get contents from a text file and save its values

Question

I need to get the contents of a text file called file.txt. The contents of that file are:

word1,word 2,word 3 1,another word 1,

I have a config.php which includes:

$file = "file.txt";
$value = explode(",", $file);

And script.php file which will execute other commands based on $value which includes:

if (count(explode($value, $chat))>1) {

After that, it will execute a command if the $value was detected in $chat. So, I need the $value to be a separate word in file.txt.

How can I do this?

If you're looking for more flexibility, you might want to try using preg_split rather than explode, which splits on a regular expression. For example, to split on newlines and commas, you could use this:

$text = file_get_contents('text.txt');    
$values = preg_split('/[\n,]+/', $text);

Testing it out:

$s = "word1,word 2\n word 3";     
print_r(preg_split('/[\n,]+/', $s));

Output:

Array
(
    [0] => word1
    [1] => word 2
    [2] =>  word 3
)

Putting that into your script:

$file = "file.txt";
$text = file_get_contents($file);
$values = preg_split('/[\n,]+/', $text);

Then $values is an array, which you can loop over in the other script:

foreach ($values as $value) {
    // do whatever you want with each value
    echo $value;
}
