I think the title itself is pretty self-explanatory. Is there any function 开发者_开发百科in powerbuilder which is equivalent to PHP's "explode" function?
For PHP's "explode", see the following link : PHP explode
Not built-in but the PFC String Service has of_parse_to_array()
which does the same thing as PHP's explode()
, except for limit. If you're not using PFC you could just lift of_parse_to_array()
(keeping the copyright notice, of course), or you could grab pfc_n_base, n_base, pfc_n_cst_string, and n_cst_string and have the whole string service. If you really need limit, it's easy to add an overloaded version of of_parse_to_array()
that implements limit.
Powerbuilder being used almost exclusively for database-intensive applications, it may be more expedient to use your database system for that.
If you're using Sybase SQL Anywhere, a runtime of which ships with Powerbuilder, you could use the sa_split_list
system procedure
Or you can build your own. The PFC includes this function you could use
//////////////////////////////////////////////////////////////////////////////
//
// Function: of_ParseToArray
//
// Access: public
//
// Arguments:
// as_Source The string to parse.
// as_Delimiter The delimeter string.
// as_Array[] The array to be filled with the parsed strings, passed by reference.
//
// Returns: long
// The number of elements in the array.
// If as_Source or as_Delimeter is NULL, function returns NULL.
//
// Description: Parse a string into array elements using a delimeter string.
