I would suggest that the patterns from Hammadi dali are slightly wrong. The first finds lines that have 31 at position 5, the second at position 6, however if you want the characters "31" to start in either position 4 or position 5, you can merge the suggestion from Hammadi dali to be just:-
This is explained as the ^ marking the start of a line and the . being any single character. The | is a logical or so it will find either a line starting with any three characters then 31 or a line starting with any four characters then 31.
I hope that this helps

strspn
STRSPN(3) 1 STRSPN(3)strspn - Finds the length of the initial segment of a string consisting entirely of characters contained within a given mask.SYNOPSIS
int strspn (string $subject, string $mask, [int $start], [int $length])
DESCRIPTION
Finds the length of the initial segment of $subject that contains only characters from $mask.
If $start and $length are omitted, then all of $subject will be examined. If they are included, then the effect will be the same as call-
ing strspn(substr($subject, $start, $length), $mask) (see "substr" for more information).
The line of code:
<?php
$var = strspn("42 is the answer to the 128th question.", "1234567890");
?>
2 to $var, because the string "42" is the initial segment of $subject that consists only of characters contained within "1234567890".
PARAMETERS
o $subject
- The string to examine.
o $mask
- The list of allowable characters.
o $start
- The position in $subject to start searching. If $start is given and is non-negative, then strspn(3) will begin examining $sub-
ject at the $start'th position. For instance, in the string ' abcdef', the character at position 0 is ' a', the character at posi-
tion 2 is ' c', and so forth. If $start is given and is negative, then strspn(3) will begin examining $subject at the $start'th
position from the end of $subject.
o $length
- The length of the segment from $subject to examine. If $length is given and is non-negative, then $subject will be examined for
$length characters after the starting position. If $length is given and is negative, then $subject will be examined from the
starting position up to $length characters from the end of $subject.
RETURN VALUES
Returns the length of the initial segment of $subject which consists entirely of characters in $mask.
EXAMPLES
Example #1
strspn(3) example
<?php
// subject does not start with any characters from mask
var_dump(strspn("foo", "o"));
// examine two characters from subject starting at offset 1
var_dump(strspn("foo", "o", 1, 2));
// examine one character from subject starting at offset 1
var_dump(strspn("foo", "o", 1, 1));
?>
The above example will output:
int(0)int(2)int(1)NOTES
