When you meet scientific notation

The solution is to

Use the PHP formatting number function:number_format()

number_format() function formats numbers by grouping thousands.

Note: This function supports one, two or four parameters (not three).

Syntax:

number_format(number,decimals,decimalpoint,separator)

• number Required. The number to format. If no other parameters are set, the number is formatted without a decimal point and with a comma (,) as the thousands separator.

• decimals Optional. Specify the number of decimals. If this parameter is set, numbers are formatted using a period (.) as the decimal point.

• decimalpoint Optional. Specifies the string used as the decimal point.

• separator Optional. Specifies the string used as thousands separator. Only the first character of the parameter is used. For example, "xxx" only outputs "x".

  Note: If this parameter is set, all other parameters are required.

The usage method is as follows:

echo number_format("5000000")."<br>";
//5,000,000
echo number_format("5000000",2)."<br>";
//5,000,000.00
echo number_format("5000000",2,",",".");
//5.000.000,00

There is also a chestnut online:

//举个例子
echo '1869879738796128';
//默认结果为：1.8698797387961E+15

//解决办法
echo number_format(‘1869879738796128’, 0, '', '');
//输出结果为：1869879738796128
