<?php
$tvPrograms = array('Simpsons', 'Southpark', 'Disney Time');
$data = '<tr><td>%col%</td><td>%col%</td><td>%col%</td></tr>';
$htmlDoc = preg_replace_callback('/%col%/', function($item) use(&$tvPrograms) {
return array_shift($tvPrograms);
}, $data);
print $htmlDoc;
?>
# Result:
<tr><td>Simpsons</td><td>Southpark</td><td>Disney Time</td></tr>

I meant to say "pass it an array of matches and an array of replacements"

First of all, using preg_replace here is a sin! You should be using
str_replace, and if you were using str_replace you would not have to worry,
since it has this feature. But, assuming that you did need to match a regular
expression, well, then just do array_fill for your search and pass it an array
of matches and an array of keys and you will be good to go. So no, you don't
really need this feature.

''If pattern is an array and replacement is a string; then this replacement
string is used for every value of pattern. The converse would not make sense,
though.'' (http://www.php.net/manual/function.preg-replace.php)
I don't agree. The converse is a feature that I would like to be available.
Have a look at the following example:
<?php
$tvPrograms = array ( 'Simpsons', 'Southpark', 'Disney Time' );
$data = '<tr><td>%col%</td><td>%col%</td><td>%col%</td></tr>';
$htmlDoc = preg_replace ( '/%col%/', $tvPrograms, $data );
print $htmlDoc;
?>
This will not work. But wouldn't it be nice if it did?
That is, replace match number n with $tvPrograms[n] in $data.
Thanks in advance for any comments.
Best regards, Joel Jacobson
