Executing a user Function in a array with php

Question

I have an array containing much more items than just this one. This is just an example of an item.

[0] => Array
        (
            [id] => 6739380664
            [created_at] => 1260991464
            [text] => @codeforge thx for following
            [source] => web
            [user] => Array
                (
                    [id] => 90389269
                    [name] => Lea@JB
                    [screen_name] => Lea_JB
                    [description] => Fan of JB and Daourite singers!! (:
                    [location] => Germany
                    [url] => 
                    [protected] => 
                    [followers_count] => 33
                    [profile_image_url] => http://a3.01/Usher_und_JB_normal.jpg
                )

            [truncated] => 
            [favorited] => 
            [in_reply_to_status_id] => 
            [in_reply_to_user_id] => 18055539
        )

And I have a function

function parseLink($text)
{
  $text = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]","<a href=\"\\0\">\\0</a>", $text);
  return $text;
}

How can I apply my function parseLink($text) for the array item text , without having to go through an loop?

that it returns the whole array containing all all fields as it was, but with the modiefied array field text ? its not just the item $myarray[0]; there are more items like $myarray[1],$myarray[2] and soon, I hope I could explain my question clearly.

Thanks

Answer 1

You can accomplish this in 2 different ways:

1) You could use the return value of parseLink() and re-assign the variable in the array:

$myText = parseLink($myArray[0]['text']);
$myArray[0]['text'] = $myText;

2) You can modify your parseLink() function to accept the argument by reference which would cause it to be modified in place:

function parseLink(&$text)
{
    $text = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]","<a href=\"\\0\">\\0</a>", $text);
    return $text;
}

parseLink($myArray[0]['text']);

Answer 2

Edit: my mistake, try this:

$myFunction = function parseLink($text) { /* do stuff with $text */ };

array_map($myFunction,$myArray);

Answer 3

// assume your array is stored in $myArray
parseLink($myArray[0]['text']);

You should change your function to pass by reference as well:

function parseLink(&$text)
{
  $text = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]","<a href=\"\\0\">\\0</a>", $text);
}

Please note that you had a bug in your parseLink() function as well that I fixed.

Answer 4

function parseLink($data)
{
  if(is_array($data) && isset($data['text']))
  {
    $data['text'] = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]","<a href=\"\\0\">\\0</a>", $data['text']);
  } elseif(is_string($data))
  {
     $data = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]","<a href=\"\\0\">\\0</a>", $data);
  }


  return $data;
}

array_map('parseLink', $myArray);
