I find the quickest and easiest way to work with a PHP array in Javascript is to do this:

PHP:

$php_arr = array('a','b','c','d');

Javascript:

//this gives me a JSON object
js_arr = '<?php echo JSON_encode($php_arr);?>';


//Depending on what I use it for I sometimes parse the json so I can work with a straight forward array:
js_arr = JSON.parse('<?php echo JSON_encode($php_arr);?>');

It can be done in a safer way   If your PHP array contains special characters  you need to use rawurlencode   in PHP and then use decodeURIComponent   in JS to escape those  And parse the JSON to native js  Try this   var data   JSON parse          decodeURIComponent                lt   rawurlencode json encode  data     gt                     console log data

I m going to assume that the two arrays you ve given for PHP and JS are not related  and they re just examples of how arrays look in the two languages  Clearly you re not going to be able to convert those sequences of letters and numbers into those city names   PHP provides a function to convert PHP arrays into Javascript code  json encode     technically  it s JSON format  JSON stands for JavaScript Object Notation   Use it like this    lt script type  text javascript  gt   lt  php  php array   array  abc   def   ghi     js array   json encode  php array   echo  var javascript array       js array      n     gt   lt  script gt    See also the manual page I linked above for more information   Note that json encode   is only available in PHP 5 2 and up  so if you re using an older version  you ll need to use an existing one -- the PHP manual page also includes comments with functions written by people who needed it   but that said  if you re using anything older than PHP 5 2 you should upgrade ASAP

For a multidimensional array in PHP4 you can use the following addition to the code posted by Udo G   function js str  s       return     addcslashes  s    0   37               function js array  array   keys array      foreach   array as  key   gt   value         new keys array    keys array       new keys array      key      if is array  value                     echo  javascript array         foreach  new keys array as  key            echo       key                     echo     new Array             js array  value   new keys array         else         echo  javascript array         foreach  new keys array as  key            echo       key                     echo       js str  value                                             echo  var javascript array   new Array      js array  php array  array

so simple       use this method    lt  php echo json encode  your array     gt      in laravel blade        use this method      str replace   amp quot        json encode  your array         working for associated and unassociated array

User · Answer

You do not have to call parseJSON since the output of json encode is a javascript literal  Just assign it to a js variable    lt script type  text javascript  gt        Assign php generated json to JavaScript variable     var tempArray    lt  php echo json encode  php array     gt         You will be able to access the properties as      alert tempArray 0  Key    lt  script gt

If you need a multidimensional PHP array to be printed directly into the html page source code  and in an indented human-readable Javascript Object Notation  aka JSON  fashion  use this nice function I found in http   php net manual en function json-encode php 102091 coded by somebody nicknamed  bohwaz     lt  php  function json readable encode  in   indent   0   from array   false          myself     FUNCTION          escape   function   str                return preg replace      b t n r f                  1    str                out            foreach   in as  key  gt  value                 out    str repeat   t    indent   1            out           escape  string  key                   if  is object  value     is array  value                          out      n                out      myself  value   indent   1                     elseif  is bool  value                          out     value    true     false                     elseif  is null  value                          out     null                     elseif  is string  value                          out             escape  value                           else                        out     value                      out       n              if   empty  out                  out   substr  out  0  -2               out   str repeat   t    indent       n     out       out      n    str repeat   t    indent              return  out       gt

Spudley s answer is fine      Security Notice  The following should not be necessary any longer for you   If you don t have PHP 5 2 you can use something like this   function js str  s        return       addcslashes  s    0   37                 function js array  array         temp   array map  js str    array       return       implode       temp            echo  var cities      js array  php cities array
