You need to use the static keyword in your function declaration, so for instance:
<?php function myfunc() { static $myfunctionvariable = 1; echo "the number $myfunctionvariable\n"; $myfunctionvariable++; } myfunc(); //1 myfunc();//2 myfunc();//3 ?>

The use of the static keyword is helping to assign the value 1 once into the variable, and each time function is called,the number is incrementing its value by 1.
