Preg_match_all pattern

[AAb]

I have a template string that contains a set of tags that follow this schema:

$template = '
[[begin_Credit_payment]]
text1
[[end_Credit_payment]]

              [[begin_COD_payment]]
              text2
              [[end_COD_payment]] ';

if ( preg_matchl("/[{2}begin(.+)payment]{2}(.+)[{2}end(\$1)payment]{2}/" , $template ) ) {

echo "OK";
}

I assume the problem is with my $1, as I have not used PHP's pattern matching that much (used to Perl). The only requirement for the matching is that the middle word (Credit or COD) is the same in both the begin and end tags.

Can someone help me fix my pattern?

if ( preg_matchl("/[{2}begin(.+)payment]{2}[a-zA-Z0-9]+[{2}end(\$1)payment]{2}/" , $template ) ) {

try that and let me know.

This still won't work, but if I do

preg_match("/[{2}begin(Credit)payment]{2}.+[{2}end_Credit_payment]{2}/" )

this works ok.

I just need to know how to match the first parenthesized object in the pattern properly. \$1 doesn't seem to work properly.
