PHP — Convert string to bigint

Question

I have the following string which i need to convert to integer or bigint.

$test=\"99999977706\";

I tried:

echo (int)$test;
         


        

Answer 1

For arbitrary length integers use GMP.

Answer 2

In your snippet $test is already a number, more specifically a float. PHP will convert the contents of $test to the correct type when you use it as a number or a string, because the language is loosely typed.

Answer 3

MySQL isn't going to know the difference. Just feed the string into your query as though it is a number without first type casting it in PHP.

For example:

$SQL = "SELECT * FROM table WHERE id = $test";

Answer 4

working solution :

<?php
   $str = "99999977706";
   $bigInt = gmp_init($str);
   $bigIntVal = gmp_intval($bigInt);
   echo $bigIntVal;
   ?>

It will return : 99999977706
