Explode Spilt & Arrays

[wwfc_barmy_army]

Hey Guys,

 

I've got this code:

while($row = mysql_fetch_array($result))
	{
		 $tagstringarray[]=$row['mycolumn'];

	}
 }

 foreach ($tagstringarray as $tag) {
	$pieces[] = explode(",", $tag);
 }

  foreach ($pieces as $tag) {
	echo $tag . "<br/>";
 }
	print_r ($pieces);

 

My database has a number of records which are tags, so are seperated by commas. eg. "tag1, tag2, tag3", but some just contain 1 tag eg "tag1".

 

This seems to put it as (presumably) a multi dimensional array, any ideas how I can return it all to one single dimensional array?

 

Thanks.

Opposite of explosion is implosion

 

implode

I'm getting error:

 

implode() [function.implode]: Invalid arguments passed in C:\wamp\www\myfile.php  on line 14

 

just swapped explode for implode. Any ideas?

 

Thanks.

Why would you swap one for the other? If you don't wan't to explode this string, just don't use explode...

 

while($row = mysql_fetch_array($result)) {
  $tagstringarray[]=$row['mycolumn'];
}

foreach ($tagstringarray as $tag) {
  echo $tag."<br/>";
}

the record contains either "tag1" or multiple tags "tag1, tag2, tag3". I want it to get all the individual tags and put them into an array. See what i mean?

[Mchl]

That's what your original code does...

It produces a multidimenstional array rather than a single array

[Mchl]

How about:

 

$pieces = array();
foreach ($tagstringarray as $tag) {
  $pieces = array_merge($pieces,explode(",", $tag));
}

var_dump($pieces);

That got it. Cheers.

$tagString = '';
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
   $tags       = explode(',', $row['mycolumn']);
   $tagString .= implode('<br />', $tags) . '<br />';
}

echo $tagString;
var_dump($tagString);   

 

That work ok?
