经测试代码如下:
/**
* 通过print输出不同格式的字符串
*
* @param
* @arrange (编程之家) jb51.cc
**/
// report all errors:
error_reporting(E_ALL);
// the full path to the current file
print __FILE__;
// print the current line
print __LINE__;
// print the current class name
print __CLASS__;
// print the current method name
print __METHOD__;
// the current directory
print dirname(__FILE__);
// directory separator of the current
// system (windows = \ and linux = /)
print DIRECTORY_SEPARATOR;
// server variables:
print $_SERVER[HTTP_HOST];
print $_SERVER[REQUEST_URI];
// more: HTTP_REFERER,SCRIPT_NAME,SERVER_URL
// output all:
print_r($_SERVER);
// constants:
if (!defined('SOMETHING')) {
define(SOMETHING,foobar);
}
print SOMETHING;
// special syntax for long strings:
// the variable goes till it finds
// the closing word EOF; (it can also be renamed)
$test =<<<EOF
This is an example of an <b>long</b> variable.
You can also put {$some_variables} in here :-)
EOF;
// ^ do not use any spaces in the line above (just EOQ;)
// sprintf usage:
print sprintf(here you see var1: %s and var2: %s,$var1,$var2);
// this function prints it's own name (test):
function test(){
print __FUNCTION__;
}
// more reserved constants at:
