Taking an array and inserting the data into a new array

[WatsonN]

I am working on a script that will take the data of one array and put it into a new one.

All I'm sure about as of now it I will need a while loop. (Maybe?)

 

I have a form where you would post a list of search terms

<?php 
if (isset($_POST['songs'])) {
$list = $_POST['songs'];
$list = htmlentities($list);
$list = str_replace(" ", "%20", $list);
$list = explode("\n", $list);
print "<pre>";
print_r($list);
print "</pre>";
} else {
?>
<form method="post">
<input type="submit" value="submit" />
<textarea name="songs" id="songs" />
</form>
<?php
}
?>

 

Then it needs to go into this array

$feed_url = array(
'feed://gdata.youtube.com/feeds/api/videos?q=$list[0]',
'feed://gdata.youtube.com/feeds/api/videos?q=$list[1]',
'feed://gdata.youtube.com/feeds/api/videos?q=$list[2]',
'feed://gdata.youtube.com/feeds/api/videos?q=$list[3]',
'feed://gdata.youtube.com/feeds/api/videos?q=$list[4]', 
        // So on and so forth
);

 

The problem is this first array can be as short as one or possibly up to 1000 and I just want to see if you can do it dynamically or not

 

I know it's possible but I just can't figure it out on my own.

[denno020]

Can't you just use count() to see the size of the second array, and then use that value as the terminating value for a for loop.

 

Something like:

for($i = 0 ; $i <= count($arrayOne); $i++){

$arrayTwo = $arrayOne;

}

 

Please excuse any syntax mistakes, it's been a little while since I've done PHP programming, so I may have written that in a Java type format by mistake.. But that should be the general idea I would think.

 

Hope that helps

do is for echoing something and you did write it correctly

I tried a while loop but it used all my memory trying to do it. . .

while ($data = $list) 
{ 
  $SongList .= 'feed://gdata.youtube.com/feeds/api/videos?q='; 
  $SongList .= $data; 
  $SongList .= '&orderby=relevance\n'; 
} 

[premiso]

$SongList = array();
foreach ($list as $data) {
    $SongList[] = 'feed://gdata.youtube.com/feeds/api/videos?q=' . $data . '&orderby=relevance';
}

var_dump($SongList);

 

Something like that?

[denno020]

I think you need a double equals? ($data == $list)

 

Otherwise you're saying "move contents of $list into $data", and that doesn't really make sense as the condition of a while loop..

@premiso That was exactly it

@denno020 Mo, that didn't make sense, I didn't think that through
