php converts data For decimal
1, use the bindec() function--binary number to decimal number
bindec() function converts a binary number to a decimal number.

2. Use the octdec() function--octal number to decimal number
octdec() function to convert octal number is a decimal number.
<?php echo octdec("36") . "<br>"; echo octdec("12") . "<br>"; echo octdec("3063") . "<br>"; echo octdec("106"); ?>
3. Use the hexdec() function--hexadecimal number to decimal number
hexdec() function Convert hexadecimal number to decimal number.
<?php echo hexdec("1e") . "<br>"; echo hexdec("a") . "<br>"; echo hexdec("11ff") . "<br>"; echo hexdec("cceeff"); ?>
4. Use the base_convert() function--convert between arbitrary bases
base_convert() function in any base Convert numbers between.
Syntax:
base_convert(number,frombase,tobase);
Parameters | Description |
---|---|
number | Required. Specifies the number to be converted. |
frombase | Required. Specifies the original base of the number. Between 2 and 36 (inclusive). Numbers above decimal are represented by the letters a-z, such as a for 10, b for 11, and z for 35. |
tobase | Required. Specifies the base to be converted. Between 2 and 36 (inclusive). Numbers above decimal are represented by the letters a-z, such as a for 10, b for 11, and z for 35. |
Example: Convert other bases to decimal
<?php echo base_convert("cceeff",16,10) . "<br>";//16进制转10进制 echo base_convert("3063",8,10) . "<br>";//8进制转10进制 echo base_convert("11000110011",2,10);//2进制转10进制 ?>
