# PHP base_convert() function (with example)

Hi everyone,

I am currently working on a PHP project and I came across the base_convert() function. I have read the PHP documentation about it, but I would like some clarification and maybe a practical example to better understand how it works.

From what I understand, the base_convert() function is used to convert a number from one base to another. But I am not quite clear on how to use it correctly. Can someone provide me with a simple example that demonstrates how to use the base_convert() function?

## All Replies Hey there,

I've actually used the base_convert() function in one of my previous projects, so I can definitely help shed some light on it. The function is indeed useful for converting a number from one base to another.

Let me provide you with a simple example to illustrate how it works. Let's say we want to convert the number "10" from base 10 (decimal) to base 2 (binary). We can use the base_convert() function for this.

```php```\$decimalNumber = 10;
\$binaryNumber = base_convert(\$decimalNumber, 10, 2);
echo \$binaryNumber; // Output: 1010
``````

In this example, we pass the decimal number "10" as the first argument to base_convert(). The second argument represents the current base, which is 10 in this case. Finally, the third argument is the target base, which is 2 for binary.

The base_convert() function will convert the decimal number "10" to its binary representation "1010" and store it in the \$binaryNumber variable. When we echo \$binaryNumber, it will output "1010".

Remember to adjust the arguments of base_convert() based on the actual bases you want to convert between.

I hope this clears things up and helps you understand how to use the base_convert() function effectively. Let me know if you have any further questions!

Best regards,

## Related Topics Howdy everyone,

I'm jumping in here to share my personal experience with the base_convert() function. I recently had a project where I needed to convert a number from base 2 (binary) to base 16 (hexadecimal). The base_convert() function came to the rescue, and I'd like to walk you through an example.

Consider the binary number "1101" that we want to convert to its hexadecimal equivalent:

```php```\$binaryNumber = '1101';
\$hexNumber = base_convert(\$binaryNumber, 2, 16);
echo \$hexNumber; // Output: D
``````

In this example, we pass the binary number "1101" as the first argument to the base_convert() function. The second argument denotes the current base, which is 2 for binary. Finally, we set the target base as 16 for hexadecimal.

When we execute the code, the base_convert() function handles the conversion of the binary number "1101" to its hexadecimal representation, which is simply "D". The echoed result is "D".

Make sure to adjust the arguments of base_convert() based on your specific base conversion requirements.

I hope this personal example helps you grasp the base_convert() function better. If you have any further questions or need more assistance, feel free to ask!

Best regards, Hey folks,

I've also worked on a project where I had to utilize the base_convert() function, and I'd be glad to share my experience and provide you with another example.

So, let's suppose we want to convert a number from base 16 (hexadecimal) to base 8 (octal). In this case, we can leverage the base_convert() function to accomplish the conversion.

Here's a sample snippet to give you a clear picture:

```php```\$hexNumber = 'FF';
\$octalNumber = base_convert(\$hexNumber, 16, 8);
echo \$octalNumber; // Output: 377
``````

In the above example, we have the hexadecimal number "FF" passed as the first argument to the base_convert() function. The second argument indicates the current base, which is 16 for hexadecimal. Lastly, we set the target base, 8 for octal, as the third argument.

Upon execution, the base_convert() function will convert the hexadecimal value "FF" to its octal representation, resulting in "377". When we echo the \$octalNumber, the output will be "377".

Remember to adjust the arguments accordingly based on the specific base conversions you require.

I hope this adds to your understanding of how the base_convert() function works and helps you in your PHP project. Feel free to reach out if you have any further queries!

Warm regards,
