Use wordwrap   to truncate the string without breaking words if the string is longer than 50 characters  and just add     at the end    str    input  if  strlen   input   gt  50         str   explode    n   wordwrap   input  50         str    str 0              echo  str    Otherwise  using solutions that do substr   input  0  50   will break words

I use this solution on my website  If  str is shorter  than  max  it will remain unchanged  If  str has no spaces among first  max characters  it will be brutally cut at  max position  Otherwise 3 dots will be added after the last whole word   function short str  str   max   50         str   trim  str       if  strlen  str   gt   max             s pos   strpos  str                 cut    s pos     false     s pos  gt   max           str   wordwrap  str   max         cut            str   explode        str            str    str 0                     return  str
