Making PHP var dump values display one line per value

Question

When I echo var dump   variable   I get one long  wrapping line with all varable s and values like    kt login user    gt   string 8   teacher1    kt login id    gt   string 3   973    kt campusID    gt   string 4   9088    kt positionID    gt   string 1   5     Is there a way I can make each value display on its own line for ease of reading  Something like this     kt login user    gt   string 8   teacher1     kt login id    gt   string 3   973     kt campusID    gt   string 4   9088     kt positionID    gt   string 1   5

I ve also researched this issue and not found the right answer   This doesn t work for me   echo   lt pre gt     var dump  variable      lt  pre gt      This will not provide a nice display of the array for me  with line breaks  I m using Firefox 31 3 0   However  after some experimentation  this solved the problem  notice the php is closed at first          gt   lt pre gt  lt  php echo var dump  variable    gt  lt  pre gt   lt  php       This solves the problem and displays a nice  easy-to-read array for me on my browser   You see how the  tags are not wrapped in PHP  only the echo var dump part is

For devs needing something that works in the view source and the CLI  especially useful when debugging unit tests   echo vd    foo   gt 1   bar   gt 2      function vd  in      ob start       var dump  in     return   n    preg replace     gt   r n s         gt     ob get clean         Yields   array 1       0    gt  array 2         foo    gt  int 1       bar    gt  int 2

If you got XDebug installed  you can use it s var dump replacement  Quoting      Xdebug replaces PHP s var dump   function for displaying variables  Xdebug s version includes different colors for different types and places limits on the amount of array elements object properties  maximum depth and string lengths  There are a few other functions dealing with variable display as well    You will likely want to tweak a few of the following settings      There is a number of settings that control the output of Xdebug s modified var dump   function  xdebug var display max children  xdebug var display max data and xdebug var display max depth  The effect of these three settings is best shown with an example  The script below is run four time  each time with different settings  You can use the tabs to see the difference     But keep in mind that XDebug will significantly slow down your code  even when it s just loaded  It s not advisable to run in on production servers  But hey  you are not var dumping on production servers anyway  are you

I didn t wanna stop using var dump  variable  die    and using pre tags and loops seems overkill to me  so since I am looking at the dump in a browser  I just right click the page and choose Inspect  I use Chrome   The Elements section of the Developer Tools show the variable in a very readable format

var export will give you a nice output  Examples from the docs    a   array  1  2  array   a    b    c     echo   lt pre gt     var export  a  true      lt  pre gt      Will output   array     0   gt  1    1   gt  2    2   gt     array       0   gt   a       1   gt   b       2   gt   c

Use output buffers  http   php net manual de function ob-start php   lt  php     ob start        var dump   SERVER         dump   ob get contents        ob end clean         echo   lt pre gt   dump  lt  pre gt      gt    Yet another option would be to use Output buffering and convert all the newlines in the dump to  lt br gt  elements  e g   ob start    var dump   SERVER    echo nl2br ob get clean

I really love var export    If you like copy paste-able code  try   echo   lt pre gt     var export  data  true      lt  pre gt      Or even something like this for color syntax highlighting   highlight string   lt  php n  data   n    var export  data  true       n  gt

I usually have  a nice function to handle output of an array  just to pretty it up a bit when debugging   function pr  data        echo   lt pre gt        print r  data      or var dump  data       echo   lt  pre gt        Then just call it  pr  array       Or if you have an editor like that saves snippets so you can access them quicker instead of creating a function for each project you build or each page that requires just a quick test   For print r   echo   lt pre gt    print r  data  1     lt  pre gt      For var dump     echo   lt pre gt    var dump  data     lt  pre gt      I use the above with PHP Storm  I have set it as a pr tab command

Personally I like the replacement function provided by Symfony s var dumper component  Install with composer require symfony var-dumper and just use dump  var   It takes care of the rest  I believe there s also a bit of JS injected there to allow you to interact with the output a bit

Wrap it in  lt pre gt  tags to preserve formatting

For me the right answer was   echo   lt pre gt     var export  var  true      lt  pre gt      Since var dump  var  and var export  var  do not return a string  you have to use var export  var  true  to force var export to return the result as a value
