I've written a function in a class
public $delimiter = ';';
....
public function some_function(){
echo $this->delimiter; // yields: ;
$SOME_ARRAY= explode($this->delimiter,$some_string);
echo $this->delimiter // yields: 1
So, running explode changes the value of the class variable $delimiter.
It's obvious I'm stepping on something, but I'm not sure what other than
there is a delimiter in explode. What does $this mean inside the explode
function?

The following code works fine here.
<?php
class MyClass {
private $delimiter = ';';
public function myfunc() {
$str = 'abd;def;ghi';
echo $this->delimiter . "\n";
$arr = explode($this->delimiter, $str);
echo $this->delimiter . "\n";
}
}
$mc = new MyClass();
$mc->myfunc();
?>
$this in the explode() function means the same thing it does anywhere
else - it is referencing the object the function is a member of. In
this case it says you want the $delimiter member of the object (instead
of some other $delimiter variable).
I suspect your problem is somewhere else.

The error must be outside the shown code, as is the case with setting of
$some_string. The parameters here are okay.
Maybe just do a string search on "delimiter"?
/Str.
