将浮点数转换为int或字符串

Question

I am retrieving a Facebook ID and I am getting a float:

float(1.1262850591603E+16)

How could I convert it to int (or string) to use it here?

I tried intval function, but it returns a wrong result:

<?php
intval(1.1262850591603E+16); // returns -1062487752
?>

Thank you!

Answer 1

I found the problem and the solution reading the comments :)

The problem: I was retrieving data from a webservice via curl and json_encoding the result. At this point, json_encode converts bigints into floats.

I solved it passing JSON_BIGINT_AS_STRING argument to json_encode.

It's documented in PHP documentation: http://php.net/manual/es/function.json-decode.php

您可以使用strval将其转换为字符串strval : //php.net/manual/zh/function.strval.php

strval($your_float_variable);
