Hi,
Is there really a difference between these two, std::hex and ios::hex??
I stumbled upon reading a line, "std::ios::hex is a bitmask (8 on gcc) and works with setf(). std::hex is the operator". Is this true?
Thanks (0 Replies)

I need to change it so it contains a hex value of '0D0A0A'

ini_get
INI_GET(3) 1 INI_GET(3)ini_get - Gets the value of a configuration optionSYNOPSIS
string ini_get (string $varname)
DESCRIPTION
Returns the value of the configuration option on success.
PARAMETERS
o $varname
- The configuration option name.
RETURN VALUES
Returns the value of the configuration option as a string on success, or an empty string for null values. Returns FALSE if the configura-
tion option doesn't exist.
EXAMPLES
Example #1
A few ini_get(3) examples
<?php
/*
Our php.ini contains the following settings:
display_errors = On
register_globals = Off
post_max_size = 8M
*/
echo 'display_errors = ' . ini_get('display_errors') . "
";
echo 'register_globals = ' . ini_get('register_globals') . "
";
echo 'post_max_size = ' . ini_get('post_max_size') . "
";
echo 'post_max_size+1 = ' . (ini_get('post_max_size')+1) . "
";
echo 'post_max_size in bytes = ' . return_bytes(ini_get('post_max_size'));
function return_bytes($val) {
$val = trim($val);
$last = strtolower($val[strlen($val)-1]);
switch($last) {
// The 'G' modifier is available since PHP 5.1.0
case 'g':
$val *= 1024;
case 'm':
$val *= 1024;
case 'k':
$val *= 1024;
}
return $val;
}
?>
The above example will output something similar to:
display_errors = 1
register_globals = 0
post_max_size = 8M
post_max_size+1 = 9
post_max_size in bytes = 8388608
NOTES
Note
When querying boolean values
A boolean ini value of off will be returned as an empty string or "0" while a boolean ini value of on will be returned as "1". The
function can also return the literal string of INI value.
Note
When querying memory size values
Many ini memory size values, such as upload_max_filesize, are stored in the php.ini file in shorthand notation. ini_get(3) will
return the exact string stored in the php.ini file and NOT its integer equivalent. Attempting normal arithmetic functions on these
values will not have otherwise expected results. The example above shows one way to convert shorthand notation into bytes, much like
how the PHP source does it.
