Checking string with only one digit

[web4]

Hi i've been thinkign this in 1 day already and i think i need some help

 

Here's a code that need to be revised

 

<?php

/*** a simple string ***/
$string = 'samples7';

/*** try to match letters with single number in it but limited to 8 characters and not less than 5 characters ***/
if(preg_match("/([a-zA-Z]+?=\d){5,8}$/", $string))
        {
        /*** if we find the word white, not followed by house ***/
        echo 'Found a match';
    }
else
        {
        /*** if no match is found ***/
        echo 'No match found';
        }
?>

 

How could i revised that code to work correctly? Thanks

Something like this ought to work...

 

$pattern = '#^(?=[a-z]*[0-9][a-z]*$).{5,8}$#i';

Try this pattern:

$pattern = '/(.[^\d]{4,7}\d)/';

[cags]

That will match a pattern that start with anything, followed by 4 - 7 non-numbers followed by a number, meaning it will allow it to start and end with a number but have no other numbers (i.e. have two in, which is not what was requested), or only one number which must be at the end.

web4, did you get this sorted out? Of the two patterns offered, I'd go with cags' (since, it would work as you want).
