The code below wont give the desired result.

 

while($row = mysql_fetch_array($result))

  {
  $url=$row['url'];
  $id=$row['id'];
  $num="0";
  
  $pic="messages[$num] = new Array('../$url');";  

echo $pic;

$num++;

}

 

the desired result is

 

messages[0] = new Array('../$url');

messages[1] = new Array('../$url'); 

messages[2] = new Array('../$url'); 

messages[3] = new Array('../$url'); and so on...

 

Can someone please throw a bone here?

Try

<?php
$num=0;
while($row = mysql_fetch_array($result)) {
  
  $url=$row['url'];
  $id=$row['id']; 
  $pic="messages[".$num."] = new Array('../$url');"; 

echo $pic;
$num++;}

Hello,

You can't increment a string, which $num was before. Also, you won't get any results from putting $num inside the while loop either because it'll always reset itself to zero. To do this, you have to put it outside the loop.

$num = 0;
while($row = mysql_fetch_array($result)) {
  $url=$row['url'];
  $id=$row['id'];
  
  $pic="messages[$num] = new Array('../$url');";  
  echo $pic;
  $num++;
}
