Programming PHP

number_format
string number_format(double number[, int precision[, string decimal_separator,
string thousands_separator]])
Creates a string representation of number. Ifprecision is given, the number is rounded to
that many decimal places; the default is no decimal places, creating an integer. If decimal_
separator and thousands_separator are provided, they are used as the decimal-place character
and thousands separator, respectively. They default to the English locale versions (“.”
and “,”). For example:
$number = 7123.456;
$english = number_format($number, 2); // 7,123.45
$francais = number_format($number, 2, ',', ' '); // 7 123,45
$deutsche = number_format($number, 2, ',', '.'); // 7.123,45
If rounding occurs, proper rounding is performed, which may not be what you expect (see
round).
ob_end_clean
void ob_end_clean( )
Turns off output buffering and empties the current buffer without sending it to the client.
See Chapter 13 for more information on using the output buffer.
ob_end_flush
void ob_end_flush( )
Sends the current output buffer to the client and stops output buffering. See Chapter 13 for
more information on using the output buffer.
ob_get_contents
string ob_get_contents( )
Returns the current contents of the output buffer; if buffering has not been enabled with a
previous call to ob_start( ), returns false. See Chapter 13 for more information on using
the output buffer.
ob_get_length
int ob_get_length( )
Returns the length of the current output buffer, or false if output buffering isn’t enabled.
See Chapter 13 for more information on using the output buffer.
