Below is my code in php,and I am getting error:
Parse error: syntax error, unexpected '[' in /LR_StaticSettings.php on line 4
<?php
class StaticSettings{
function setkey ($key, $value) {
self::arrErr[$key] = $value; // error in this line
}
}
?>
I want to use statically not $this->arrErr[$key] so that I can get and set static properties without creating instance/object.
Why is this error? Can't we create static array?
If there is another way, please tell me. Thanks
You'd need to declare the variable as a static member variable, and prefix its name with a dollar sign when you reference it:
class StaticSettings{
private static $arrErr = array();
function setkey($key,$value){
self::$arrErr[$key] = $value;
}
}
You'd instantiate it like this:
$o = new StaticSettings;
$o->setKey( "foo", "bar");
print_r( StaticSettings::$arrErr); // Changed private to public to get this to work
You can see it working in this demo.
class StaticSettings{ private static $arrErr = array(); function setkey($key,$value){ self::$arrErr[$key] = $value; } } . it was my silly mistake.private static $arrErr = array();
Your code doesn't define $arrErr as a static member variable. You should declare it as
<?php
class StaticSettings{
public static $arrErr = array();
function setkey($key,$value){
self::arrErr[$key] = $value;
}
}
?>
$arrErras a static member variable. You should declare it aspublic static $arrErr = array();
