code works just need simple explanation of this for statement

[Immyphp]

Hi i cant get my head around something so here goes

// create an array of the urls

$url_array = array ();
for ($count =1; $row = $result->fetch_row(); ++$count) {
$url_array[$count] = $ row[0[;
}
return $url_array;

ok not fussed about the syntax or even geting it working, as its from a script which i know works, i just typed this out in a rush

just to clarify here im saying

while count is 1, and there is a row to fetch, increment count and then assign, that fetched row to the array?

if thats the case why is count in there? and how does the pointer go forward through the array?

[Immyphp]

oh i think i get it, the count goes up and increments the aray and saves the row in next element of the array

You could simplify it a bit by using a [man]while/man loop and using the "[]" array notation to add new elements:

$url_array = array ();
while($row = $result->fetch_row()) {
   $url_array[] = $row[0];
}
