PHP template string replace

Question

just wondering what's the best approach for template String replace.

preg_replace('/{%(\S+)%}/', 'bill', $tableOutput);

With the preg_replace, if there are lots of string needs to be replace, the function will be called many times depend on the number of string needs to be replace. Just wondering if there is a way can look though string once and replace accordingly?

Thanks

As per the fine PHP manual, you can supply preg_replace with array arguments. So, no. It won't be called many times. — user895378

Use the array syntax of preg_replace...?

preg_replace(array('/pattern1/', '/pattern2/'), array('replacement1', ...), ...)

But can you actually find the replace string and match with replacement. eg <td>{%itemname%}</td>, find the {%itemname%} and doing a match in the array['itemname'], and replace with the value?

Yes, you can use lookahead and lookbehind then replace the match. (?<=\<td\>){%item%}(?=\<\/td\>). If you need finer control using capturing groups you can capture the tag contents and replace on that using preg_replace_callback.

A simpler way would be to just use the backreference $1 in the replacement string of preg_replace however.
