I want to get the part of the string before the last occurance of "-",
for example,
$string1 = 'a-b-c-de-f-gfgh';
I want to get this part returned: a-b-c-de-f. Of course, I don't know the length of the last part.
What is the easy way to do it?
Thank you
echo substr ($string1, 0, strrpos ($string1, '-'));
strrpos() finds the last occurrence of a substring, - in this case, and substr() splits the original string from the 0th character until the nth character as defined by strrpos()
get the last occurrence of - using $x = strrpos($string1,'-');
then use substr() to return the decired string from 0 to $x
echo substr ($string1, 0, $x);
You could remove that last part:
$string = preg_replace("|-[^-]+$|", "", $string);
As an alternative to the other posters:
preg_match('/(.*)-[^-]+/', 'a-b-c-de-f-gfgh', $result);
Result:
Array
(
[0] => a-b-c-de-f-gfgh-a
[1] => a-b-c-de-f-gfgh
)
Though I like Jeroens solution more.
