Use the stringInsert function rather than the putinplace function  I was using the later function to parse a mysql query  Although the output looked alright  the query resulted in a error which took me a while to track down  The following is my version of the stringInsert function requiring only one parameter   function stringInsert  str  insertstr  pos         str   substr  str  0   pos     insertstr   substr  str   pos       return  str

Strange answers here  You can insert strings into other strings easily with sprintf  link to documentation   The function is extremely powerful and can handle multiple elements and other data types too    color    green   sprintf  I like  s apples     color     gives you the string  I like green apples

Just wanted to add something  I found tim cooper s answer very useful  I used it to make a method which accepts an array of positions and does the insert on all of them so here that is   EDIT  Looks like my old function assumed  insertstr was only 1 character and that the array was sorted  This works for arbitrary character length   function stringInsert  str   pos   insertstr        if   is array  pos              pos   array  pos         else           asort  pos              insertionLength   strlen  insertstr        offset   0      foreach   pos as  p             str   substr  str  0   p    offset     insertstr   substr  str   p    offset            offset     insertionLength            return  str
