Question

I have this string: “4702819 – 09” (without the quotes) and i want to make a pattern to change it to :
“094702819”. So basically to remove the space-space completely and to cut what came after it
to be at the beginning. So another example would be:

“5502819 – 098” to “0985502819” etc. How do i do that? do i use preg replace?

Answer 1

$string = "4702819 - 09";
$pattern = '/(\d+) - (\d+)/i';
$replacement = '$2$1';
print preg_replace($pattern, $replacement, $string);

The above will output 094702819. See the PHP manual on preg_replace() for additional examples.
