PHP base_convert( ) Math Function Last Updated : 22 Jun, 2023 Comments Improve Suggest changes Like Article Like Report The base_convert() function in PHP is used to convert a number given in an arbitrary base to a desired base. Both the base should be between 2 and 32 and bases with digits greater than 10 are represented with letters a-z i.e 10 is represented as a, 11 is represented as b and 35 is represented as z. The case of the letters is not sensitive. Syntax: string base_convert($inpNumber, $fromBase, $desBase) Parameters Used: This function accepts three parameters and are described below: $inpNumber : It is the number to be converted.$fromBase : It is the original base of the number.$desBase : It is the base to which you want to convert. Return Value: It returns a string that represents the number converted to the desired base. Examples: Input : base_convert(B296, 16, 8) Output : 131226 Input : base_convert(B296, 16, 2) Output : 1011001010010110 Input : base_convert(621, 8, 16) Output : 191 Input : base_convert(110011, 2, 16) Output : 33 Below programs illustrate the base_convert() function in PHP: Converting hexadecimal to octal: PHP <?php $hexadec = "B296"; echo base_convert($hexadec, 16, 8); ?> Output: 131226 Converting hexadecimal to binary: PHP <?php $hexadec = "B296"; echo base_convert($hexadec, 16, 2); ?> Output: 1011001010010110 Converting octal to hexadecimal: PHP <?php $octal = "621"; echo base_convert($octal, 8, 16); ?> Output: 191 Converting binary to hexadecimal: PHP <?php $binary = "110011"; echo base_convert($binary, 2, 16); ?> Output: 33 Reference: http://php.net/manual/en/function.base-convert.php Comment More infoAdvertise with us Next Article PHP base_convert( ) Math Function S Shubrodeep Banerjee Follow Improve Article Tags : Misc Web Technologies PHP PHP-math PHP-function +1 More Practice Tags : Misc Similar Reads PHP mb_convert_kana() Function The mb_convert_kana() is an inbuilt function in PHP that is used to convert text into full-width and half-width.
