PHP Explode and Implode a String

Question

I am half way done and struck at imploding on the output.

I have a string as

$text = "test | (3), new | (1), hello | (5)";
$text = explode(",", $text);
foreach ($text as $t){
    $tt = explode(" | ", $t);
    print_r($tt[0]);
}

When I print the above array, it gives me test new hello as needed, now, I need to put a comma like this test, new, hello

I searched and could not achieve hence posting here to get help.

$text = "test | (3), new | (1), hello | (5)";
echo preg_replace('# \| \(.*?\)#', '', $text);

EDIT: to reach result like 'test',' 'new', 'hello'

$text = "test | (3), new | (1), hello | (5)";
$text = preg_replace('# \| \(.*?\)#', '', $text);
echo "'" . preg_replace('#,#', "', '", $text) . "'";

Cool, thanks, your final edit worked. Can you please explain within the preg_replace, how have you done? I will accept this answer.

@sammry, this is matching (and then substituting with empty string) using RegEx, also known as Regular Expressions. Here's quickly googled-up something that should help you get the idea and learn how to use them: regexone.com/cheatsheet .

by the way, if I have to quote it like this, 'test',' 'new', 'hello'?

It matches " | (X)" pattern, just escaping | symbol, because unescaped means OR, exaping ( and ) because it is also symbols, .*? this means everything inside will be matched "non greedy". # this is start stop signs

Don't you think regex is a bit overkill? Some simple php methods could do this eg implode?

Yes, you can push them to array and implode later on

$text = "test | (3), new | (1), hello | (5)";

$text = explode(",", $text);

$arr = array();

foreach ($text as $t){
    $tt = explode(" | ", $t);
    $arr[] = $tt[0];
}

echo implode(", ", $arr);

Go for the $arr[] = "'".$tt[0]."'";

1- Implode is a function in php where you can convert a array into string Ex-

$arr = array('Hello','World!','Beautiful','Day!');

echo implode(" ",$arr);

?>

2- Explode is a function in php where you can convert a string into array

Ex-

$str = "Hello world. It's a beautiful day.";

print_r (explode(" ",$str));

?> `
