Array problem – no. 2

What am I doing wrong here ?

[code=php]
$operator = “randomtxt”;
$i = 1;

foreach ($_GET as $key => $value) {
if (stristr($key,’phone’) && (strlen($value) > 0)) {
echo $i;
if ($i == 1) {
$operator=””;
}
$what .= ” “.$operator.” `handsets` LIKE ‘%”.$value.”%’ “;
echo $operator;
$i++;
}
[/code]

the echo from $i outputs “1234” so it goes up each time, however it sets $operator = “” in each loop, so operator is always empty, even though it’s if $i == 1 and $i is sometimes equal to 2 or 3!!

Wel confused, can’t think what i’ve missed now!

Thank you ?

@andre4s_yJul 09.2008 — When you run your code for the first time, it will set :
<i>
</i>$operator = "randomtxt";

After that, it will loop via foreach.

When it first loop, and when $i==1, in will redefine $operator
<i>
</i>$operator = "";

So the rest of foreach, $operator will empty...

No wonder about that...

The answer is : do not redefine $operator, but modify $what.

Hope this help you.

@Phill_PaffordJul 09.2008 — Looks like you don't set operator again after it's equal to ""

Your code
[code=php]
// You set $operator here
$operator = "randomtxt";

// Counter is set
$i = 1;

// Loop through array

foreach ($_GET as $key => $value)
{
// Some soft of check/validation
if (stristr($key,'phone') && (strlen($value) > 0))
{
// Print $i to the screen, this is set to 1 on the first loop
echo $i;

// so the condition is met on the first loop
if ($i == 1)
{
// Reset $operator to ""
$operator="";

// Looks like you need an else condition to
// reset the $operator to something
}

// $operator will be "" unless reset to another value
// regardless of the value of $i
$what .= " ".$operator." handsets LIKE '%".$value."%' ";

// Should print ""
// Never gets reset
echo $operator;

// Increment
$i++;
}
[/code]

Hope this helps
