As of PHP 7 1 0  negative string offsets are also supported  So  if you keep up with the times  you can access the last character in the string like this    str -1    DEMO  At the request of a  mickmackusa  I supplement my answer with possible ways of application    lt  php   str  abcdef   var dump  str -2         gt  string 1   e    str -3       var dump  str            gt  string 6   abc ef   var dump isset  str -4           gt  bool true   var dump isset  str -10          gt  bool false

A string in different languages including C sharp and PHP is also considered an array of characters   Knowing that in theory array operations should be faster than string ones you could do    foo    bar      lastChar   strlen  foo  -1  echo  foo  lastChar     firstChar   0  echo  foo  firstChar     However  standard array functions like   count      will not work on a string

Remember  if you have a string which was read as a line from a text file using the fgets   function  you need to use substr  string  -3  1  so that you get the actual character and not part of the CRLF  Carriage Return Line Feed    I don t think the person who asked the question needed this  but for me  I was having trouble getting that last character from a string from a text file so I m sure others will come across similar problems

I d advise to go for Gordon s solution as it is more performant than substr      lt  php    string    abcdef    repetitions   10000000   echo   n n   echo  ---------------------------------- n   echo  repetitions     repetitions    n   echo  ---------------------------------- n   echo   n n     start   microtime true   for  i 0   i lt  repetitions   i         x   substr  string  -1    echo  substr   took      microtime true  -  start     seconds n     start   microtime true   for  i 0   i lt  repetitions   i         x    string strlen  string -1    echo  array access took      microtime true  -  start     seconds n    die      outputs something like   ----------------------------------   10000000 repetitions     ----------------------------------   substr   took 2 0285921096802seconds   array access took 1 7474739551544seconds

I can t leave comments  but in regard to FastTrack s answer  also remember that the line ending may be only single character   I would suggest  substr trim  string   -1    EDIT  My code below was edited by someone  making it not do what I indicated   I have restored my original code and changed the wording to make it more clear   trim  or rtrim  will remove all whitespace  so if you do need to check for a space  tab  or other whitespace  manually replace the various line endings first    order   array   r n     n     r     string   str replace  order       string    lastchar   substr  string  -1

Or by direct string access    string strlen  string -1     Note that this doesn t work for multibyte strings  If you need to work with multibyte string  consider using the mb   string family of functions   As of PHP 7 1 0 negative numeric indices are also supported  e g just  string -1

You can find last character using php many ways like substr   and mb substr        If you   re using multibyte character encodings like UTF-8  use mb substr instead of substr   Here i can show you both example    lt  php     echo substr  testers   -1       echo mb substr  testers   -1     gt    LIVE DEMO
