An expression that specifies the regular expression string that is the pattern for the search. The expression must return a value that is a built-in character string, graphic string, numeric, or datetime data type.

The compiled program takes two arguments. The first is a regular expression. The second is the text to match. When run, it matches the regular expression against the text until no more matches can be found.

For information about the language elements used to build a regular expression pattern, see Regular Expression Language - Quick Reference. The regexec() function compares the null-ended string against the compiled regular expression preg to find a match between the two. The nmatch value is the number of substrings in string that the regexec() function should try to match with subexpressions in preg .
