求一个正则表达式 去除小数点后面的000

比如
8.38370000
要结果为 8.3837


8.0038370000
要结果为 8.3837


8.38370010
要结果为 8.3837001

回复讨论(解决方案)

$s =<<< TXT8.383700008.00383700008.38370010TXT;echo preg_replace('/(?<=\d)0+\b|(?<=\.)0+/', '', $s);

$string = "8.38370010";echo (float)$string;

preg_replace('/[^0]0+$/','',$s);8.0038370000 要变成 8.3837 应该是无理要求

preg_replace('/[^0]0+$/','',$s);8.0038370000 要变成 8.3837 应该是无理要求

打错了.
