PHP: Extracting a certain set of characters from a string

Hello,

I'm trying to extract a certain number regardless of where it is at in a string returned in PHP from a SMTP reply. Some examples are:

sent (250 2.0.0 Ok: queued as EC81CCC9B0)
sent (Error 5.1.1 Hard Bounce: queued as EC81CCC9B0)

etc. The number I need extracted in these two cases are the 2.0.0 and 5.1.1 for example. The number will always be 5 in length, have 2 dots and 3 numeric numbers in it as provided.


Does anyone have any suggestions on how I can extract this easily, regardless of where it is at? Thanks!

try like this if the format is fixed with space,

<?php

$str1 = "sent (250 2.0.0 Ok: queued as EC81CCC9B0)";

$pieces = explode(" ", $str1);

//print_r ($pieces);

echo $pieces[2];


// ------------------------


$str2 = "sent (Error 5.1.1 Hard Bounce: queued as EC81CCC9B0)";

$pieces1 = explode(" ", $str2);

//print_r ($pieces1);

echo "<br>".$pieces1[2];

//

?>

Is there any chance that there would be other dots in the string?

If not, then use this:

$string = "sent (250 2.0.0 Ok: queued as EC81CCC9B0)";
$array = explode(".",$string);
$first=substr( $array[0], strlen($array[0])-1, 1);
$second = $array[1];
$third = substr($array[2], 0, 1);
$newstring = $first.".".$second.".".$third;
echo $newstring;

If there might be other dots in the string, then  you will need to add checks to $first, $second, and $third to ensure they are single digit integers.
