/*
|
|
* Format a given string and invoke the given callback on each processed chunk.
|
|
* According to the PHP reference manual.
|
|
* The format string is composed of zero or more directives: ordinary characters
|
|
* (excluding %) that are copied directly to the result, and conversion
|
|
* specifications, each of which results in fetching its own parameter.
|
|
* This applies to both sprintf() and printf().
|
|
* Each conversion specification consists of a percent sign (%), followed by one
|
|
* or more of these elements, in order:
|
|
* An optional sign specifier that forces a sign (- or +) to be used on a number.
|
|
* By default, only the - sign is used on a number if it's negative. This specifier forces
|
|
* positive numbers to have the + sign attached as well.
|
|
* An optional padding specifier that says what character will be used for padding
|
|
* the results to the right string size. This may be a space character or a 0 (zero character).
|
|
* The default is to pad with spaces. An alternate padding character can be specified by prefixing
|
|
* it with a single quote ('). See the examples below.
|
|
* An optional alignment specifier that says if the result should be left-justified or right-justified.
|
|
* The default is right-justified; a - character here will make it left-justified.
|
|
* An optional number, a width specifier that says how many characters (minimum) this conversion
|
|
* should result in.
|
|
* An optional precision specifier in the form of a period (`.') followed by an optional decimal
|
|
* digit string that says how many decimal digits should be displayed for floating-point numbers.
|
|
* When using this specifier on a string, it acts as a cutoff point, setting a maximum character
|
|
* limit to the string.
|
|
* A type specifier that says what type the argument data should be treated as. Possible types:
|
|
* % - a literal percent character. No argument is required.
|
|
* b - the argument is treated as an integer, and presented as a binary number.
|
|
* c - the argument is treated as an integer, and presented as the character with that ASCII value.
|
|
* d - the argument is treated as an integer, and presented as a (signed) decimal number.
|
|
* e - the argument is treated as scientific notation (e.g. 1.2e+2). The precision specifier stands
|
|
* for the number of digits after the decimal point.
|
|
* E - like %e but uses uppercase letter (e.g. 1.2E+2).
|
|
* u - the argument is treated as an integer, and presented as an unsigned decimal number.
|
|
* f - the argument is treated as a float, and presented as a floating-point number (locale aware).
|
|
* F - the argument is treated as a float, and presented as a floating-point number (non-locale aware).
|
|
* g - shorter of %e and %f.
|
|
* G - shorter of %E and %f.
|
|
* o - the argument is treated as an integer, and presented as an octal number.
|
|
* s - the argument is treated as and presented as a string.
|
|
* x - the argument is treated as an integer and presented as a hexadecimal number (with lowercase letters).
|
|
* X - the argument is treated as an integer and presented as a hexadecimal number (with uppercase letters).

|

* Format
|
|
* Properties
|
|
* The basic element contained in an INI file is the property. Every property has a name and a value
|
|
* delimited by an equals sign (=). The name appears to the left of the equals sign.
|
|
* Example:
|
|
* name=value
|
|
* Sections
|
|
* Properties may be grouped into arbitrarily named sections. The section name appears on a line by itself
|
|
* in square brackets ([ and ]). All properties after the section declaration are associated with that section.
|
|
* There is no explicit "end of section" delimiter; sections end at the next section declaration
|
|
* or the end of the file. Sections may not be nested.
|
|
* Example:
|
|
* [section]
|
|
* Comments
|
|
* Semicolons (;) at the beginning of the line indicate a comment. Comment lines are ignored.
|

* specified.
|
|
* Arguments may be left out in order from right to left; any arguments thus omitted will be set to

* the current value according to the local date and time.
|
|
* Parameters
|
|
* $hour
|
|
* The number of the hour relevant to the start of the day determined by month, day and year.
|
|
* Negative values reference the hour before midnight of the day in question. Values greater
|
|
* than 23 reference the appropriate hour in the following day(s).
|
|
* $minute
|
|
* The number of the minute relevant to the start of the hour. Negative values reference

|
* the minute in the previous hour. Values greater than 59 reference the appropriate minute
|

* in the following hour(s).
|
|
* $second
|
|
* The number of seconds relevant to the start of the minute. Negative values reference
|
|
* the second in the previous minute. Values greater than 59 reference the appropriate
|
|
* second in the following minute(s).
|
|
* $month
|
|
* The number of the month relevant to the end of the previous year. Values 1 to 12 reference
|
|
* the normal calendar months of the year in question. Values less than 1 (including negative values)
|
|
* reference the months in the previous year in reverse order, so 0 is December, -1 is November)...
|
|
* $day
|
|
* The number of the day relevant to the end of the previous month. Values 1 to 28, 29, 30 or 31
|
|
* (depending upon the month) reference the normal days in the relevant month. Values less than 1
|
|
* (including negative values) reference the days in the previous month, so 0 is the last day
|
|
* of the previous month, -1 is the day before that, etc. Values greater than the number of days
|
|
* in the relevant month reference the appropriate day in the following month(s).
|
|
* $year
|
|
* The number of the year, may be a two or four digit value, with values between 0-69 mapping
|
|
* to 2000-2069 and 70-100 to 1970-2000. On systems where time_t is a 32bit signed integer, as
|
|
* most common today, the valid range for year is somewhere between 1901 and 2038.
|
|
* $is_dst
|
|
* This parameter can be set to 1 if the time is during daylight savings time (DST), 0 if it is not,
|
|
* or -1 (the default) if it is unknown whether the time is within daylight savings time or not.
|
