任意の数値を整形し、数文字列を取得します。

文字列 = number_format( 数値 [, 精度 [, 小数点文字, 桁区切文字]] );

$a = 10000000; $b = 1000.124; $c = 1000.125; print number_format( $a, 3, ".", "," ) . "<br>¥n"; print number_format( $a, 2, "_", "-" ) . "<br>¥n"; print "<br>¥n"; print number_format( $a ) . "<br>¥n"; print number_format( $a, 2 ) . "<br>¥n"; print number_format( $a, 2, "_", "-" ) . "<br>¥n"; print "<br>¥n"; print number_format( $b, 2, ".", "," ) . "<br>¥n"; print number_format( $c, 2, ".", "," ) . "<br>¥n"; print "<br>¥n"; print number_format( $a, 3, "点", "千" ) . "<br>¥n"; print number_format( $a, 3, "." , "千" ) . "<br>¥n"; print number_format( $a, 3, "点", "," ) . "¥n";
