There are much better ways to print variable s value in PHP  One of them is to use buildin var dump   function  If you want to use var dump    I would also suggest to install Xdebug  from https   xdebug org  since it generates much more readable printouts   The idea of printing values to browser console is somewhat bizarre  but if you really want to use it  there is very useful Google Chrome extension  PHP Console  which should satisfy all your needs  You can find it at consle com It works well also in Vivaldi and in Opera  though you will need  Download Chrome Extension  extension to install it   The extension is accompanied by PHP library you use in your code

This will work with either an array  an object or a variable and also escapes the special characters that may break your JS     function debugToConsole  msg             echo   lt script gt console log   json encode  msg     lt  script gt        Edit   Added json encode to the echo statement  This will prevent your script from breaking if there are quotes in your  msg variable
