When you do a while loop like this:
<?php
$String=array ("a","b","c");
$i=0;
while ($String[$i])
{
echo $String[$i];
$i++;
}
?>
And error reporting is set to E_ALL you get a warning message saying there's an undefined
index.
There's a simple solution to this:
<?php
$String=array ("a","b","c);
$i=0;
while ($i<count($String))
{
echo $String[$i];
$i++;
}
?>
And away the warning is!
