Returns the decimal equivalent of the hexadecimal number
|
|
represented by the <parameter>hex_string</parameter> argument.
|
|
<function>hexdec</function> converts a hexadecimal string to a
|
|
decimal number. The largest number that can be converted is
|
|
7fffffff or 2147483647 in decimal.
|
|
As of PHP 4.1.0, this function can also convert larger numbers. It returns
|
|
<type>float</type> in that case.

</para>
|
|
<para>
|
|
<function>hexdec</function> will ignore any non-hexadecimal
|
|
characters it encounters.
