I have the following script
myclass.php
<?php
$myarray = array('firstval','secondval');
class littleclass {
private $myvalue;
public function __construct() {
$myvalue = "INIT!";
}
public function setvalue() {
$myvalue = $myarray[0]; //ERROR: $myarray does not exist inside the class
}
}
?>
Is there a way to make $myarray available inside the littleclass, through simple declaration? I don't want to pass it as a parameter to the constructor if that was possible.
Additionally, I hope that you actually CAN make global variables visible to a php class in some manner, but this is my first time facing the problem so I really don't know.
include global $myarray
at the start of setvalue()
function.
public function setvalue() {
global $myarray;
$myvalue = $myarray[0];
}
UPDATE:
As noted in the comments, this is bad practice and should be avoided.
A better solution would be this: https://stackoverflow.com/a/17094513/3407923 .
在类中,您可以使用$GLOBALS['varName'];
任何全局变量$GLOBALS['varName'];
构造一个新的单例类,用于存储和访问要使用的变量?
$GLOBALS['myarray'] = array('firstval','secondval');
在课堂上你可以使用$ GLOBALS ['myarray']。
Why dont you just use the getter and setter for this?
<?php
$oLittleclass = new littleclass ;
$oLittleclass->myarray = array('firstval','secondval');
echo "firstval: " . $oLittleclass->firstval . " secondval: " . $oLittleclass->secondval ;
class littleclass
{
private $myvalue ;
private $aMyarray ;
public function __construct() {
$myvalue = "INIT!";
}
public function __set( $key, $value )
{
switch( $key )
{
case "myarray" :
$this->aMyarray = $value ;
break ;
}
}
public function __get( $key )
{
switch( $key )
{
case "firstval" :
return $this->aMyarray[0] ;
break ;
case "secondval" :
return $this->aMyarray[1] ;
break ;
}
}
}
?>
