  • In glob, ? matches any single character, and in regex . does the same.
  • In glob, * matches any 0-max characters, and in reges .* doees that.
  • In glob you can match any character in a list, with ranges, like characters legal for C variable names: [a-zA-Z0-9_] Regex does the same, the same way but can also do negative lists, like not a number: [^0-9].
  • In regex you have * for any count, but not in glob.
  • Extended regex, like egrep or grep -E, has + for count 0 or one, \{##\} for specific count, and \{##-##\} for ranges of count.
  • Extended regex has parentheses and OR operator | for lists of alternatives, and glob in case does the same: From (Tom|Dick|Harry).
  • Extended regex has morphed in ways that make old scripts break, like for beginning of word \< disappeared and \b came in its place for the position at the edge of a word. One friend speculates that the PERL lovers had their way over traditional UNIX thought.
  • Apparently bash has extended globbing available, too. As I recall, the context can be switched between regex and glob with different wrapping operators in if/while tests.

SQLSRV_FREE_STMT(3)													       SQLSRV_FREE_STMT(3)

sqlsrv_free_stmt - Frees all resources for the specified statement

SYNOPSIS
bool sqlsrv_free_stmt (resource $stmt) DESCRIPTION
Frees all resources for the specified statement. The statement cannot be used after sqlsrv_free_stmt(3) has been called on it. If sql- srv_free_stmt(3) is called on an in-progress statement that alters server state, statement execution is terminated and the statement is rolled back. PARAMETERS
o $stmt - The statment for which resources are freed. Note that NULL is a valid parameter value. This allows the function to be called multiple times in a script. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 sqlsrv_free_stmt(3) example <?php $serverName = "serverNamesqlexpress"; $connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password"); $conn = sqlsrv_connect( $serverName, $connectionInfo); if( $conn === false ) { die( print_r( sqlsrv_errors(), true)); } $stmt = sqlsrv_query( $conn, "SELECT * FROM Table_1"); if( $stmt === false ) { die( print_r( sqlsrv_errors(), true)); } /*------------------------------- Process query results here. -------------------------------*/ /* Free the statement resources. */ sqlsrv_free_stmt( $stmt); ?> NOTES
The main difference between sqlsrv_free_stmt(3) and sqlsrv_cancel(3) is that a statement resource cancelled with sqlsrv_cancel(3) can be re-executed if it was created with sqlsrv_prepare(3). A statement resource cancelled with sqlsrv_free_statement(3) cannot be re-executed. SEE ALSO
