Print array to a file

Question

I would like to print an array to a file   I would like the file to look exactly similar like how a code like this looks   print r   abc   assuming  abc is an array   Is there any one lines solution for this rather than regular for each look   P S - I currently use serialize but i want to make the files readable as readability is quite hard with serialized arrays

I just wrote this function to output an array as text   Should output nicely formatted array   IMPORTANT NOTE   Beware of user input    This script was created for internal use    If you intend to use this for public use you will need to add some additional data validation to prevent script injection   This is not fool proof and should be used with trusted data only   The following function will output something like    var   array     primarykey    gt  array       test    gt  array         var    gt  array          1   gt  99          2   gt  500                       abc    gt   d             here is the function  note  function is currently formatted for oop implementation      public function outArray  array   lvl 0        sub    lvl 1       return           if  lvl  null          return     t  var   array  n                 foreach  array as  key   gt   mixed            key   trim  key           if  is array  mixed               mixed   trim  mixed                     if empty  key   amp  amp  empty  mixed   continue           if  is numeric  key   amp  amp   empty  key              if  key                        key   null              else                key       addslashes  key                                      if  mixed     null              mixed    null             elseif  mixed     false              mixed    false             elseif  mixed     true              mixed    true             elseif  mixed                     mixed                               CONVERT STRINGS  true    false  and  null  TO true  false and null           uncomment if needed           elseif  is numeric  mixed   amp  amp   is array  mixed   amp  amp   empty  mixed                if  mixed     false   amp  amp   mixed     true   amp  amp   mixed     null                   mixed       addslashes  mixed                                           if is array  mixed              if  key     null                return      t  str repeat   t    sub    key   gt  array  n                return     this- gt outArray  mixed   sub                return      t  str repeat   t    sub      n               else                return      t  str repeat   t    sub   array  n                return     this- gt outArray  mixed   sub                return      t  str repeat   t    sub      n                                     else             if  key     null                return      t  str repeat   t    sub    key   gt   mixed  n               else                return      t  str repeat   t    sub   mixed    n                                   if  lvl  null          return      t   n             return  return        Alternately you can use this script I also wrote a while ago   This one is nice to copy and paste parts of an array     Would be near impossible to do that with serialized output    Not the cleanest function but it gets the job done   This one will output as follows    array  key    key2      value    array  key    key3      value2    array  x     7   array  y    z      abc     Also take care for user input  Here is the code   public static function prArray  array   path false   top true         data            delimiter                 p   null      if is array  array          foreach  array as  key   gt   a           if  is array  a     empty  a              if is array  a                 data     path      key      array      delimiter              else                data     path      key          htmlentities addslashes  a          delimiter                        else              data    self  prArray  a   path      key      false                                   if  top          return             foreach explode  delimiter   data  as  value           if  empty  value               return      array   value   lt br gt                             echo  return            return  data

Either var export or set print r to return the output instead of printing it   Example from PHP manual   b   array        m    gt   monkey         foo    gt   bar         x    gt  array   x    y    z       results   print r  b  true       results now contains output from print r   You can then save  results with file put contents  Or return it directly when writing to file   file put contents  filename txt   print r  b  true

Here is what I learned in last 17 hours which solved my problem while searching for a similar solution   resources    http   php net manual en language types array php  Specific Code        The following is okay  as it s inside a string  Constants are not looked for    within strings  so no E NOTICE occurs here print  Hello  arr fruit            Hello apple   What I took from above   arr fruit  can go inside      double quotes  and be accepted as string by PHP for further processing   Second Resource is the code in one of the answers above   file put contents  file  print r  array  true   FILE APPEND    This is the second thing I didn t knew  FILE APPEND   What I was trying to achieve is get contents from a file  edit desired data and update the file with new data but after deleting old data   Now I only need to know how to delete data from file before adding updated data   About other solutions   Just so that it may be helpful to other people  when I tried var export or Print r or Serialize or Json Encode  I either got special characters like    or   or   or    in the file or some kind of error  Tried too many things to remember all errors  So if someone may want to try them again  may have different scenario than mine   they may expect errors   About reading file  editing and updating   I used fgets   function to load file array into a variable   array  and then use unset  array x    where x stands for desired array number  1 2 3 etc  to remove particular array  Then use array values   to re-index and load the array into another variable and then use a while loop and above solutions to dump the array  without any special characters  into target file    x 0   while   x  lt    lines-1     lines is count  array  i e  number of lines in array  array                txt    array  x            file put contents  file txt    txt  FILE APPEND            x

Just use print r     Read the documentation       If you would like to capture the output of print r    use the return parameter  When this parameter is set to TRUE  print r    will return the information rather than print it    So this is one possibility    fp   fopen  file txt    w    fwrite  fp  print r  array  TRUE    fclose  fp

You can try this   myArray as the Array   filename    mylog txt    text       foreach  myArray as  key   gt   value         text     key        value   n      fh   fopen  filename   w   or die  Could not open log file     fwrite  fh   text  or die  Could not write file     fclose  fh
