cant increment PHP class's static variable

Hello there. Here is my php code

PHP Code:


		
			
class car{

static $one=1;



static function change()

{

 self::$one=self::$one++;



}



}

car::$one=2;

echo car::$one."<br />";

echo car::change();

echo car::$one."<br />";

echo car::change();

echo car::$one."<br />";

echo car::change();

echo car::$one."<br />";

I expected it to increment the variable but it echoed 2 2 2 2 instead of expected 2 3 4 5

Thank you for your attention!!!

Will be waiting :pleased:

Re: cant increment PHP class's static variable

Please just delete "echo"-s in front of change functions .. even in that case it didnt work

Re: cant increment PHP class's static variable

try

PHP Code:


		
			
class car
{ 
static $one=1; 

static function change() 
{ 
 return self::$one++; 

} 

}

$i;
for ($i = 1; $i < 11; $i++)
{
echo car::change();
}

the for loop just makes it print out a certain number of times, while the change function changes the value on each call.

if you use the below script it will show the value as 10

PHP Code:


		
			
<?php

class car
{ 
static $one=1; 

static function change() 
{ 
 return self::$one++; 

} 

}

car::change();
car::change();
car::change();
car::change();
car::change();
car::change();
car::change();
car::change();
car::change();
echo car::$one;

?>

Hope this works, I did test the code and it worked on my machine using php 5.2.11. and 5.3.5
