Carved in mystic runes upon the very living rock, the last words of ImOk
of comp.lang.php make plain:
I have this PHP statement which works fine and breaks down a string of
lines delimited with a \r into an array.
$arrList=split("\r", $strList);
But what I really want is to be able to tell it to split out only the
strings that start with the letter "b".
E.g. I thought this would work "b\W\r"
I tried every regular expression but cant figure it out. I could use
some other function combinations to achive this but I though if there
is a way to do it with just spli()
Since split() deletes the delimiter string that it's splitting on, I
don't think that function is going to give you what you want, regardless
of regex.
Try the preg_match_all() function.
An alternative would be to convert the appropriate \r characters to
something else unlikely to be in the string (such as a \3, for example),
and split on that:
$strList = preg_replace("/(b.+)\r/U", "\\1\3", $strList);
$arrList = explode("\3", $strList);
