在PHP中设置精度

Question

I have installed PHP 5.5 on my laptop, who's running Windows. I'm accessing Smartsheet API, and I supposed to get a column id a number with 18 digits(or sometimes 17). But I get a scientific number:

1.5441916385627E+15, not 1544191638562692

I ran the script, in a Ubuntu server environment, and I see 1544191638562692. The same, a ran in a OS X Maverick environment, and it's the same the integer format.

I was searching for this matter, and seems to be the precision.

If I'm setting in php, the precision 14 for the OS X Maverick environment like this:

<?php
ini_set('precision', 14);

    echo (float)$col->id;
    // 1.5441916385627E+15
?>

I get also the scientific number.

Can anybody help me with an idea?

You can output the numbers in the same way on all machines using the formatted string functions in PHP, see http://nl1.php.net/manual/en/function.sprintf.php for the documentation.

So if you would like the integer as a whole you would use:

printf("%u", $number);
