Question

Hi this is probably really basic but cant do it for the life off me.

i have a foreach outputting values.

$tags = get_the_tags(); 

foreach($tags as $v) {

    echo $v;
}

this will output

php,css,cms,seo

i need to put all those into a single variable so i can do the following.

$keywords = "<meta name='keywords' content='".$tags."'>";
return $keywords;

can someone help i have tried

 $keywords = "<meta name='keywords' content='".foreach($tags as $v) {echo $v;}."'>";
    return $keywords;

obviously getting errors from this and its wrong how is it done???

Thanks

Use implode():

$keywords = "<meta name='keywords' content='".implode(',', $tags)."'>";

You can also achieve the same result if you build a temporary variable using foreach:

$tmp = '';
foreach($tags as $v) {
    $tmp .= $v;
}

$keywords = "<meta name='keywords' content='".$tmp."'>";
