Question

I have a string abc@123 (hello world) posted 23 July 1990 20:34:00 +000. I want output as hello world abc (abc@123) posted "on" 23 July 1990 "at" 20:34:00 Should it be done with explode or preg() function??

Answer 1

I’d use a regex with preg_replace, here is an example that can likely be improved upon:

$str = 'abc@123 (hello world) posted 23 July 1990 20:34:00 +000';
echo preg_replace( '/([A-Za-z]+)@(\d+) \(([A-Za-z ]+)\) posted (\d+ [A-Za-z]+ \d+) (\d+:\d+:\d+) .*/', '$3 $1 ($1@$2) posted "on" $4 "at" $5', $str);

Output:

hello world abc (abc@123) posted “on” 23 July 1990 “at” 20:34:00
