Print elements of an array and concatenate them in a string

[g_p_java]

Hello i have an array which consists of elements, and i would like to print the array without using vardump but as a string since it contains in every index a character

e.r. ar[1] = 'a';

      ar[2] = ' b';

 

Print Output shall be: ab and NOT

 { [0]=>  string(1) "a" [1]=>  string(1) "b" 

 

Then i would like to store the output in an empty string $str = ' ';

 

Then every time i take the elements of the array i shall concatenate them together using a '_'e.g.

 

         Print_Array                STRING                                     FINAL

1st           ab              $str = $str.concat(ab.concat('_'))         ab_                     

2nd          cd              $str = $str.concat(cd.concat('_'))          ab_cd_               

3nd          ef               $str  = $str.concat(kij)                        ab_cd_ef

 

Is the code fine?

 

May you please help me?

Take a look at the implode() function.

e.g.

$items = array('a','b','c');
// will produce the string a_b_c
print implode("_",$items);

In fact, implode() is even normally faster than concatenation.

Thanks for replying, but is there any function for printing all the elements of the array as a string?

I mean only the array to print.

That is what implode() does. I'm not sure what it is your after. You may need to explain a bit better.

Well thanks for implode, but it's just that firstly i have to print the array and afterwards concatenate that result with _.

Then i have to wait for the second print of the array and concatenate the 2nd output of the array with the previous one.

 

ab_cd (ab 1st print of array)

            (cd 2nd print of the array)

Then i would suggest storing your data back into another array via your loop and then concatenating using implode():

// build up an array so it looks like
$array = array('ab','cd','ef','gh');
// produces ab_cd_ef_gh
print implode("_", $array);

Thanks for replying!

I have the array $charArray and i do print $charArray; and it doesn't print anything!

[JonnoTheDev]

You cannot print an array using print. you can however use print_r();

You must implode the array before it can be printed as a string.

Why not post the code you are using? That way we can specifically show you what to do...

[g_p_java]

$arr_codes = array();

$arr_codes["0"] = 'j';
$arr_codes["1"] = 'a';
$arr_codes["2"] = 'b';
$arr_codes["3"] = 'c';
$arr_codes["4"] = 'd';
$arr_codes["5"] = 'e';
$arr_codes["6"] = 'f';
$arr_codes["7"] = 'g';
$arr_codes["8"] = 'h';
$arr_codes["9"] = 'i';

var_dump($arr_codes);                       //Print arr_codes to see if everything is inserted well

$encoding_ipPart = array();                  //Create new array

echo "NEW NEW NEW NEW CODE" . "<br />";

$ip = $_SERVER["REMOTE_ADDR"];

$splitIp = explode(".", $ip);

foreach($splitIp as $ipPart){

   //echo "SplitIp  :   , $ipPart " . "<br />"; //SplitIP

   for($i=0;$i<strlen($ipPart);$i++){

              //echo "Take each Character :   , $ipPart[$i] " . "<br />"; 

              $charArray[] = $ipPart[$i];

              $int_char = $arr_codes[$ipPart[$i]];     // e.g. int_char maybe '9'

               //echo "Hm... :   , $int_char " . "<br />"; 

             $encoding_ipPart[] = $int_char;
        }

echo "Print $encoding ipPart  .<br />";
var_dump($encoding_ipPart);  //Here prints : e.g. if we have $ipPart = 97 , then $encoding_ipPart  shall print  id

//$array_with_all_ipParts shall store every $encoding_ipPart e.g. it shall look like this $array = array('ab','cd','ef','gh');

$array_with_all_ipParts[] = $encoding_ipPart;  
$encoding_ipPart = array(); //clear array

}

var_dump($charArray);
print implode("_",$array_with_all_ipParts);

//$array_with_all_ipParts shall print di_jk_lo

 

Hope you understand!

 

It's just that my program shall take as input an ip and output a specific string related to the ip that visits the site.

 

Thanks in advance!

Hello, i would like to make a program which is going to take as input the client's IP and output a string related to that IP.

That program has to tokenize every IP and produce a specific and unique string for that IP , that means that i have to produce for every token a specific string.So, i have to convert every number to a string

The algorithm i'm thinking is: have an array of characters like

 

$arr_codes = array();

$arr_codes["0"] = 'j';
$arr_codes["1"] = 'a';
$arr_codes["2"] = 'b';
$arr_codes["3"] = 'c';
$arr_codes["4"] = 'd';
$arr_codes["5"] = 'e';
$arr_codes["6"] = 'f';
$arr_codes["7"] = 'g';
$arr_codes["8"] = 'h';
$arr_codes["9"] = 'i';

 

e.g. input: 97.172.1.2   

Tokenise 97    172  1    2

Output    ig_agb_a_b

 

The code i have is:

 

 

$encoding_ipPart = array();
$array_with_all_ipParts = array();

$j = 0;

$ip = $_SERVER["REMOTE_ADDR"];

$splitIp = explode(".", $ip);

foreach($splitIp as $ipPart){

   for($i=0;$i<strlen($ipPart);$i++){

              $charArray[] = $ipPart[$i];       
              $int_char = $arr_codes[$ipPart[$i]];     
             $encoding_ipPart[] = $int_char;    

        }

   $array_with_all_ipParts[$j] = $encoding_ipPart;

    echo "Array with all ipParts : " . "<br />";
    var_dump($array_with_all_ipParts);
  
    $j = $j + 1;

   $encoding_ipPart = array();
}

echo "PHP PHPH PHPH HELP  " . "<br />";
$new_array = implode(" ",$Whole_String);
print $new_array;

 

May you please help me?

The program has to take the IP of the client and convert it into a string.

But it doesn't output the string as i desire,

Also what about the algorithm?Is it a good choice for converting an IP into a unique string, so that everytime a specific IP visits the site, the same string is going to be generated.
