NUMFMT_SET_TEXT_ATTRIBUTE(3)						 1					      NUMFMT_SET_TEXT_ATTRIBUTE(3)

NumberFormatter::setTextAttribute - Set a text attribute

	Object oriented style

SYNOPSIS

       public bool NumberFormatter::setTextAttribute (int  $attr, string  $value)

DESCRIPTION

	Procedural style
       bool numfmt_set_text_attribute (NumberFormatter	$fmt, int  $attr, string  $value)

	Set  a	text  attribute associated with the formatter. An example of a text attribute is the suffix for positive numbers. If the formatter
       does  not  understand  the  attribute,  U_UNSUPPORTED_ERROR  error  is  produced.  Rule-based  formatters  only	understand   NumberFormat-
       ter::DEFAULT_RULESET and NumberFormatter::PUBLIC_RULESETS.

PARAMETERS

	      o $fmt
		-NumberFormatter object.

	      o $attr
		- Attribute specifier - one of the text attribute constants.

	      o $value
		- Text for the attribute value.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      numfmt_set_text_attribute(3) example

	      <?php
	      $fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
	      echo "Prefix: ".numfmt_get_text_attribute($fmt, NumberFormatter::NEGATIVE_PREFIX)."
";
	      echo numfmt_format($fmt, -1234567.891234567890000)."
";
	      numfmt_set_text_attribute($fmt, NumberFormatter::NEGATIVE_PREFIX, "MINUS");
	      echo "Prefix: ".numfmt_get_text_attribute($fmt, NumberFormatter::NEGATIVE_PREFIX)."
";
	      echo numfmt_format($fmt, -1234567.891234567890000)."
";
	      ?>

       Example #2

	      OO example

	      <?php
	      $fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
	      echo "Prefix: ".$fmt->getTextAttribute(NumberFormatter::NEGATIVE_PREFIX)."
";
	      echo $fmt->format(-1234567.891234567890000)."
";
	      $fmt->setTextAttribute(NumberFormatter::NEGATIVE_PREFIX, "MINUS");
	      echo "Prefix: ".$fmt->getTextAttribute(NumberFormatter::NEGATIVE_PREFIX)."
";
	      echo $fmt->format(-1234567.891234567890000)."
";
	      ?>

       The above example will output:

       Prefix: -
       -1.234.567,891
       Prefix: MINUS
       MINUS1.234.567,891
