It could mean that you get some (old) php4 code and are supposed to port it to php5.
In that case the code should run with the setting error_reporting(E_ALL|E_STRICT)
without warning messages. Also check the description of each function/method whether it contains a "This function has been DEPRECATED" note/warning somewhere.
Imo likely candidates are: sessions, classes, ereg (posix regular expressions) maybe even register_globals and allow_call_time_pass_reference.
Maybe you're also supposed to spot the usage of "old" workarounds and to replace them with newer functions. E.g.
// $s = preg_replace('/foo/i', 'bar', $input);
// use php5's str_ireplace() instead
$s = str_ireplace('foo', 'bar', $input);
Ama bu kapalı ettik konulara bağlıdır.
Örneğin "Php5 için Port Bu php4 kod":
<?php
class Foo {
var $protected_v;
function Foo($v) {
$this->protected_v = $v;
}
function doSomething() {
if ( strlen($this->protected_v) > 0 ) {
echo $this->protected_v{0};
}
}
}
session_start();
if ( session_is_registered($bar) ) {
$foo = new Foo($bar);
$foo->doSomething();
}
Ve cevap olabilir
<?php
class Foo {
// php5 introduced visibility modifiers
protected $v;
// the "preferred" name of the constructor in php5 is __construct()
// visibility modifiers also apply to method declarations/definitions
public function __construct($v) {
$this->v = $v;
}
public function doSomething() {
if ( strlen($this->v) > 0 ) {
// accessing string elements via {} is deprecated
echo $this->v[0];
}
}
}
session_start();
// session_is_registered() and related functions are deprecated
if ( isset($_SESSION['bar']) ) {
$foo = new Foo($_SESSION['bar']);
$foo->doSomething();
}
