php - Separated commas array as different string -

i have separated commas array, , needed separate each word separate construction.

for example:

author1, author2, author3 

to:

<meta content="author1"> <meta content="author2"> <meta content="author3"> 

trying this:

<?php $ex = explode(',', $input); foreach ($ex $authorc) { echo '<meta content="$ex">'; } 

recieved this:

<meta content="$ex"><meta content="$ex"> 

thanks in advance!

replace

echo '<meta content="$ex">'; 

with

echo '<meta content="'.$authorc.'">';
