Update  After further tests  I don t recommend using this any more  It caused a problem for me when using the updated string in a MySQL query  and changing to substr fixed the problem  I thought about deleting this answer  but comments suggest it is quicker somehow so someone might have a use for it  You may find trimming the updated string resolves string length issues     Sometimes you don t need a function    str 0          For example    str    AHello    str 0        echo  str      Hello    This method modifies the existing string rather than creating another
