So the beginning of the retrieval is 4 characters from the end of the string rather than the beginning. Accordingly, using -1 as parameter, makes the last character to be removed and -2 is deleting the last two characters and with passing -4, we are removing of the last four characters from our input string.

It works well when both when $string contains '/' and it does not contain '/' (it does not modify $string in this case). In this case the value of position of the beginning of the retrieval is negative. The negative values ensure that it is counted from behind and the specified number of characters will be removed. Solution #3, using preg_replace(): $string = ' echo(preg_replace('#/*$#', '/', $string)) ĭrawbacks: none.

Solution #1, using substr() + strrpos(): $string = ' $pos = strrpos($string, '/') įunction strrpos() finds the position of the last occurrence of / in the string, substr() extracts the required substring.ĭrawback: if $string does not contain '/', strrpos() returns FALSE and substr() does not return what we want.
