[RESOLVED] Break the string

tnylsej

Hi all..

I have a variable called $partno. It is in the form of abc1-DEF234. I want to retrieve only 1, DEF and 234(without leading zero if there is any) from the variable. How should I do it?

For example,

$partno ='USG2-PTR010';

I should get the output of 2, PTR and 10.

mjax

if(preg_match('/^.*([1-9]?[0-9]+)\-([A-Z]+).*$/i', $partno, $matches)) {
   echo $matches[1]."<br/>";
   echo $matches[2]."<br/>";
}

Is the part number always the exact same number of characters in that pattern, or can it vary?

clairence

preg_match('/^{.([1-9]?[0-9]+)-([A-Z]+).$/i'}

can you explain that in english, please?

My eyes always glaze over when I see these character combinations.

Regex solution if it's not fixed length:

$partno ='USG2-PTR010';
if(preg_match('/^[a-z]+(\d+)-([a-z]+)(\d+)$/i', $partno, $matches))
{
   echo "<p>Result for $partno:<br>".
        $matches[1]." - ".$matches[2]." - ".(int)$matches[3]."</p>\n";
}
else
{
   user_error("Pattern match failed on part no. '$partno'");
}

If it is fixed length, just use the substr() function to pull out the different parts of the string, and cast the last 3 digits as an integer (as I did in my preg example) so that there's no leading zero.

Yes, it's fixed length..

Thanks for all the help
