[SOLVED] explode inside array ...

[doa24uk]

Hi guys,

 

I've used this method before but only on a plain $_POST string rather than an array.

 

Here's my code, why is it returning nothing?

 

What this does is take the multi-line values from a textarea, split them at the newline character \n then place them in an array.

 

eg.

 

http://site1.com

http://site2.com

 

And what I need to get ( which is why the str_replace & explode is in there) is -->

 

site1.com

site2.com

 

 

 

// Takes value from the textarea & splits into individual array elements at the newline character
$textareaname = $_POST['links'];
$str=explode("\n", $textareaname);

// While we're looping through the textarea lines, do the following
for($i = 0; $i < count($str); $i++){

$url = $str[$i];

// Attempt at getting 'site1.com' from something like 'http://site1.com/folder/fgsjosdj2/index.html'

echo $url . "<br><br>";


//Extracts the domain from a URL
echo get_domain( $url ) . '<br />';


function get_domain( $url ) {
    if( strpos( $url, '://' ) !== false ) {
        list( $throwAway, $url ) = explode( '://', $url );
    }
    if( strpos( $url, '/' ) !== false ) {
        $url = explode( '/', $url );
        $url = array_shift( $url );
    }
    if( preg_match( '/^www[^.]*\..*/', $url ) ) {
        $url = explode( '.', $url );
        array_shift( $url );
        $url = implode( '.', $url );
    }

I'm not sure I understand. Your description sounds like you want this?

 

<?php
$textareaname = str_replace("http://", "", $_POST['links']);
$str = explode("\n", $textareaname);

foreach($str as $url) {
  echo $url . '<br />';
}
?>

You want to end up with a string again? You can use parse_url() to get the domain:

 

<?php
$array = explode(PHP_EOL, $_POST['links']);
foreach ($array as &$url) {
$url = parse_url($url, PHP_URL_HOST);
}
unset($url);
echo implode(PHP_EOL, $array);
?>

Hi guys,

 

badbad's code didn't work, cags' did but I need both the original URLs (broken by newline) and the domain only as two seperate variables.

 

I then need to put them into the DB. I can use two of cags' codes to get the relevant parts but I can't deploy them in a single loop...

 

Eg.

 

Text from textarea

 

http://site1.com/mylink.html\nhttp://site2.com/newlink

 

Required output

 

http://site1.com/mylink.html & site1.com -->  INSERT INTO DB

http://site2.com/newlink & site2.com --> INSERT INTO DB

What about it is not working? This should work:

<?php
   $urls = explode("\n", $_POST['links']);
   $domains = array();
   foreach ($urls as $url)
   {
      preg_match("/http:\/\/(.+?)\//", $url, $matches);
      $domains[] = $matches[1];
   }
?>

 

If it doesn't, the input is probably not what you are expecting.

<?php
$text = "http://site1.com/mylink.html\nhttp://site2.com/newlink";
$str = explode("\n", $text);
foreach($str as $k=>$v) {
  $sql = "INSERT INTO `table` (`url`, `domain`) 
       VALUES ('".$v."','".parse_url($v, PHP_URL_HOST)."')";
echo $sql . '<br/>';
}
?>

Gotta love those "didn't work" replies without any further details.

Sorry guys,

 

Both solutions did work, it was just me being an idiot.

 

Cags' second solution is working perfectly. Thank you very much all.

Just noticed a problem.

 

It's adding an underscore onto the end of the parse_url variables

 

eg.

 

http://1.com

http://2.com

 

Gives

 

1.com_

2.com_

Try echo'ing out the urlencode of $_POST['links'] like so.

 

<?php echo urlencode($_POST['bob']); ?>

 

I imagine then problem is that the rows are seperate by \r\n not just \n, so the whitespace character is being converted to an underscore. If thats the case changing the explode function to split on "\r\n" instead of on "\n" should solve the problem.

\r\n that was my problem .... def. all sorted now!!!

 

Damn I love this forum!!!

Guess why I split the string on the PHP_EOL constant?
