Operating Systems Linux Issue in inserting null string in array Post 302988562 by RudiC on Wednesday 28th of December 2016 08:18:35 AM

PLEASE DON'T modify posts if people have already answered, pulling the rug from under their feet!

On a vague specification without decent sample input and output data and detailed error description, you can expect very generic replies only:
- How do you tell "null strings" from normal fields - two adjacent field separators?
- What are the field separators - you seem to use awk's default?
- What is the purpose of the piped second awk command, why don't you do that in the first?
- Why do you gsub the entire line in every field's loop?
- Are you aware that the shell concatenates ALL whitespace into one space unless quoted? So, "null strings" might be lost here...

LEARN ABOUT PHP

parse_ini_string

PARSE_INI_STRING(3)							 1						       PARSE_INI_STRING(3)

parse_ini_string - Parse a configuration string

SYNOPSIS

       array parse_ini_string (string  $ini, [bool  $process_sections = false], [int  $scanner_mode = INI_SCANNER_NORMAL])

DESCRIPTION

       parse_ini_string(3) returns the settings in string $ini in an associative array.

	The structure of the ini string is the same as the php.ini's.

PARAMETERS

	      o $ini
		- The contents of the ini file being parsed.

	      o $process_sections
		-  By  setting	the  $process_sections	parameter  to  TRUE, you get a multidimensional array, with the section names and settings
		included. The default for $process_sections is FALSE

	      o $scanner_mode
		- Can either be INI_SCANNER_NORMAL (default) or INI_SCANNER_RAW. If INI_SCANNER_RAW is supplied, then option values  will  not	be
		parsed.   As  of  PHP 5.6.1 can also be specified as INI_SCANNER_TYPED. In this mode boolean, null and integer types are preserved
		when possible. String values "true", "on" and "yes" are converted to TRUE.  "false", "off", "no" and "none" are considered  FALSE.
		"null" is converted to NULL in typed mode. Also, all numeric strings are converted to integer type if it is possible.

RETURN VALUES

	The settings are returned as an associative array on success, and FALSE on failure.

NOTES

       Note

	       There  are  reserved  words which must not be used as keys for ini files. These include: null, yes, no, true, false, on, off, none.
	      Values null, off, no and false result in "", and values on, yes and true result in "1", unless INI_SCANNER_TYPED mode is used. Char-
	      acters ?{}|&~![()^" must not be used anywhere in the key and have a special meaning in the value.
