PHP爆炸和内爆字符串

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.

Answer 1

$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) . "'";
