If you re going to do PHP in the command line  I recommend you install phpsh  a decent PHP shell  It s a lot more fun  Anyway  the php command offers two switches to execute code from the command line  -r  lt code gt         Run PHP  lt code gt  without using script tags  lt      gt  -R  lt code gt         Run PHP  lt code gt  for every input line  You can use php s -r switch as such  php -r  echo function exists  quot foo quot      quot yes quot     quot no quot     The above PHP command above should output no and returns 0 as you can see   gt  gt  gt  php -r  echo function exists  quot foo quot      quot yes quot     quot no quot    no  gt  gt  gt  echo      print the return value of the previous command 0  Another funny switch is php -a  -a               Run as interactive shell  It s sort of lame compared to phpsh  but if you don t want to install the awesome interactive shell for PHP made by Facebook to get tab completion  history  and so on  then use -a as such   gt  gt  gt  php -a Interactive shell  php  gt  echo function exists  quot foo quot      quot yes quot     quot no quot   no php  gt   If it doesn t work on your box like on my boxes  tested on Ubuntu and Arch Linux   then probably your PHP setup is fuzzy or broken  If you run this command  php -i   grep  API   You should see  Server API   gt  Command Line Interface  If you don t  this means that maybe another command will provides the CLI SAPI  Try php-cli  maybe it s a package or a command available in your OS  If you do see that your php command uses the CLI  command-line interface  SAPI  Server API   then run php -h   grep code to find out which crazy switch - as this hasn t changed for year- allows to run code in your version setup  Another couple of examples  just to make sure it works on my boxes   gt  gt  gt  php -r  echo function exists  quot sg load quot      quot yes quot     quot no quot    no  gt  gt  gt  php -r  echo function exists  quot print r quot      quot yes quot     quot no quot    yes  Also  note that it is possible that an extension is loaded in the CLI and not in the CGI or Apache SAPI  It is likely that several PHP SAPIs use different php ini files  e g    etc php cli php ini vs   etc php cgi php ini vs   etc php apache php ini on a Gentoo Linux box  Find out which ini file is used with php -i   grep ini

If you re using Laravel  you can use php artisan tinker to get an amazing interactive shell to interact with your Laravel app  However  Tinker works with  quot Psysh quot  under the hood which is a popular PHP REPL and you can use it even if you re not using Laravel  bare PHP      Bare PHP   gt  gt  gt  preg match  quot  hell  quot    quot hello quot      gt  1     Laravel Stuff   gt  gt  gt  Str  slug  quot How to get the job done      quot    quot   quot      gt   quot how to get the job done quot   One great feature I really like about Psysh is that it provides a quick way for directly looking up the PHP docs from the command line  To get it to work  you only have to take the following simple steps  apt install php-sqlite3  And then get the required PHP documentation database and move it to the proper location  wget http   psysh org manual en php manual sqlite mkdir -p  usr local share psysh   amp  amp  mv php manual sqlite  usr local share psysh   Now for instance

You can use   echo   lt  php if function exists  quot my func quot    echo  quot function exists quot       php  The short tag  quot  lt     quot  can be helpful too   echo   lt    function exists  quot foo quot      quot yes quot     quot no quot      php  echo   lt    8 7 9      php  The closing tag  quot   gt  quot  is optional  but don t forget the final  quot   quot
