RENDERING AND OUTPUT
The following functions generate output. When the script is referenced by
the WebServer this output becomes part of the HTML stream. When the script
is used in the command line batch file the output is then interpreted as a
command line entry. In program execution this is simply just output.
int print ( mixed $var )
Outputs the
$var as a string. It is the functional equivalent of the
ECHO statement. This always returns 1.
int puts ( mixed $var )
Outputs the
$var as a string followed by the "\r\n" sequence. In addition
to generating a newline for formatting general output this appends the
ENTER termination needed for command execution in batch use. This always
returns 1.
string printf ( string $format [, mixed $param ] )
Outputs the formatted string defined by $format. This uses the Standard
C Library format specifiers. A variable number of
$param values may be
supplied. The formatted string is also returned. The
sprintf() function
is available for only formatting the string.
void header(string hdrline)
Adds the supplied $hdrline to HTTP response headers when rendering HTML
through the WebServer.
var_dump ( var1 [ , var2 [ , ... ] ] )
Outputs a useful description of each variable. If
var_dump() is issued
without a parameter it will dump ALL of the local variables excluding
the predefined arrays.
