Php convert string to bigint

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

$test="99999977706";

I tried:

echo [int]$test;
echo [integer]$test;
echo intval[$test];

But they are all returning me 2147483647.

How do i convert the above string to a number or bigint?

Many many thanks for all suggestions.

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";

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.

For arbitrary length integers use GMP.

You can treat the string as string without converting it.

Just use a regex to leave only numbers:

$test = "99999977706";
$test = preg_replace['/[^0-9]/', '', $test];

Problem :

In PHP, you want to convert[cast] a string to become big integer value.

Solution :

Use GNU Multiple Precision's gmp_intval[] function to convert the string to a big integer value.

For example :

Output :

123456789123456789

Notes :

See //php.net/manual/en/gmp.installation.php on how to get GMP installed on your server.

Reference :

//php.net/manual/en/book.gmp.php

//php.net/manual/en/function.gmp-intval.php
