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);8.3837 8.3837
8.3837001
8.0038370000 要变成 8.3837 应该是无理要求
$string = "8.38370010";echo (float)$string;8.3837001
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.
