If your goal is output your array to a string for debbuging  you can use the print r   function  which receives an expression parameter  your array   and an optional boolean return parameter  Normally the function is used to echo the array  but if you set the return parameter as true  it will return the array impression   Example         We create a 2-dimension Array as an example      ProductsArray   array          row array  Qty     20       row array  Product      Cars        array push  ProductsArray  row array         row array2  Qty     30       row array2  Product      Wheels        array push  ProductsArray  row array2          We save the Array impression into a variable using the print r function      ArrayString   print r  ProductsArray  1          You can echo the string     echo  ArrayString         or Log the string into a Log file      date   date  Y-m-d H i s   time          LogFile    Log txt        fh   fopen  LogFile   a   or die  can t open file         stringData    --   date   n   ArrayString   n       fwrite  fh   stringData       fclose  fh     This will be the output   Array        0    gt  Array                        Qty    gt  20              Product    gt  Cars                 1    gt  Array                        Qty    gt  30              Product    gt  Wheels

Is there any other way to convert that array into string     You don t want to convert the array to a string  you want to get the value of the array s sole element  if I read it correctly    lt  php    foo   array  18   gt   Something        value   array shift   foo      echo  value      Something      gt    Using array shift you don t have to worry about the index   EDIT  Mind you  array shift is not the only function that will return a single value  array pop     current     end     reset     they will all return that one single element  All of the posted solutions work  Using array shift though  you can be sure that you ll only ever get the first value of the array  even when there are multiple

For completeness and simplicity sake  the following should be fine    str   var export  array  true     It does the job quite well in my case  but others seem to have issues with whitespace  In  that case  the answer from ucefkh provides a workaround from a comment in the PHP manual

A For   loop is very useful  You can add your array s value to another variable like this    lt  php      dizi array  mother   father   child      This is array       sayi count  dizi       for   i 0   i lt  sayi   i               dizin      dizi  i         Now it is string                   echo substr  dizin 0 -1     Write it like string  D   gt    In this code we added  dizi s values and comma to  dizin    dizin      dizi  i        Now   dizin    mother    father    child     It s a string  but it has an extra comma     And then we deleted the last comma  substr  dizin  0  -1    Output       mother   father   child

implode or join  they re the exact same thing  would work here  Alternatively  you can just call array pop and get the value of the only element in the array

Since the issue of whitespace only comes up when exporting arrays  you can use the original var export   for all other variable types  This function does the job  and  from the outside  works the same as var export      lt  php  function var export min  var   return   false        if  is array  var              toImplode   array            foreach   var as  key   gt   value                 toImplode     var export  key  true     gt   var export min  value  true                      code    array   implode       toImplode               if   return  return  code          else echo  code        else           return var export  var   return              gt    http   www php net manual en function var-export php 54440
