PHP, gets a string between two strings in a string of characters

Br-lan Link encap:ethernet HWaddr f0:b4:29:55:6c:2e
inet addr:192.168.8.9 bcast:192.168.8.255 mask:255.255.255.0

In the above string, I want to remove the IP address between the inet addr:192.168.8.9 bcast, can I ask you how to write the positive expression of PHP? Thank you.
$return _array is the string array above.

foreach ($return _array as $value) {//if (Preg_match ("/inet addr:/i", $value, $temp _array)) if (Preg_match ("\binet addr : \b.*\bbcast\b ", $value, $temp _array)) {echo '

';p rint_r ($temp _array);//var_dump ($temp _array);}}

Up, online and more.

if (Preg_match ("[0-9]{1,3}[.] [0-9] {1,3} [.] [0-9] {1,3} [.] [0-9] {1,3} ", $value, $temp _array))//Put in the code, this line has errors, use the tool to test OK. {echo '

';//print_r ($temp _array); Var_dump ($temp _array);}

\b[0-9]{1,3}[.] [0-9] {1,3} [.] [0-9] {1,3} [.] [0-9] {1,3}\b//if (Preg_match ("/\b[0-9]{1,3}[.] [0-9] {1,3} [.] [0-9] {1,3} [.] [0-9] {1,3}\b/", $value, $temp _array)) if (Preg_match ("/[0-9]{1,3}[. ") [0-9] {1,3} [.] [0-9] {1,3} [.] [0-9] {1,3}/", $value, $temp _array))//Ok{echo '

';//print_r ($temp _array); Var_dump ($temp _array);}

if (Preg_match ("/inet addr: (. +?) \s+bcast:/", $value, $temp _array))    {        echo '

';        Print_r ($temp _array);        Var_dump ($temp _array);    }
