while loop in php with assignment operator

Question

the code I\'m looking at does this...

while ($info=mysql_fetch_array($data_jurisdiction))
{
//some stuff
}

I\'m wondering what does this wh

Answer 1

great answer from hakre. what is said is that

while ($info=mysql_fetch_array($data_jurisdiction))

will execute in the same way as this

while (mysql_fetch_array($data_jurisdiction)==true)

or even this

$info = mysql_fetch_array($data_jurisdiction);
if($info==true)

so keep in mind that if mysql_fetch_array($data_jurisdiction) returns anything that can be evaluated to false, the assignment won't work. some of those values are (and I know I will forget a few:

• 0
• "0"
• false
• "false"
• NULL
• ""
• array() (not fully sure about this one)
