php 科学计数法转换
具体看下面代码: <?php $num = number_format(1.2313223123423E+017,'','','');//后面三个参数为空 echo $num; //输出“123132231234230000” $num = number_format(1.2313223123423E+017); //后面三个参数为默认值 echo $num; //输出“123,132,231,234,230,000” $num = number_format(1.2313223123423E+017,'@','#','$');//后面三个参数为分别为'@','#','$' echo $num; //输出“123$132$231$234$230$000” ?>
