Question around Global Variable
- count is not changed anywhere (visible)
- You parse entries d, but dont use them.
- HERE, Problem is printed because $count NOT equals 1 (as it still is set to 0 and 0!=1, so it is printed).
Same question as in your other thread, what do you want to achieve?
1.
count is changed and set to 1 just below the
find statement and I wish that value to be taken over to the last if condition.
2. -d is used but its not relavent to the problem so i did not share the entire code. Let me know if you need that to debug the issue.
3. My expectation / need is
$count SHOULD equals 1

COUNT(3) 1 COUNT(3)
count - Count all elements in an array, or something in an object
SYNOPSIS
int count (mixed $array_or_countable, [int $mode = COUNT_NORMAL])
DESCRIPTION
Counts all elements in an array, or something in an object.
For objects, if you have SPL installed, you can hook into count(3) by implementing interface Countable. The interface has exactly one
method, Countable::count, which returns the return value for the count(3) function.
Please see the Array section of the manual for a detailed explanation of how arrays are implemented and used in PHP.
PARAMETERS
o $array_or_countable
- An array or Countable object.
o $mode
- If the optional $mode parameter is set to COUNT_RECURSIVE (or 1), count(3) will recursively count the array. This is particu-
larly useful for counting all the elements of a multidimensional array.
Caution
count(3) can detect recursion to avoid an infinite loop, but will emit an E_WARNING every time it does (in case the array
contains itself more than once) and return a count higher than may be expected.
RETURN VALUES
Returns the number of elements in $array_or_countable. If the parameter is not an array or not an object with implemented Countable inter-
face, 1 will be returned. There is one exception, if $array_or_countable is NULL, 0 will be returned.
Caution
count(3) may return 0 for a variable that isn't set, but it may also return 0 for a variable that has been initialized with an empty
array. Use isset(3) to test if a variable is set.
EXAMPLES
Example #1
count(3) example
<?php
$a[0] = 1;
$a[1] = 3;
$a[2] = 5;
$result = count($a);
// $result == 3
$b[0] = 7;
$b[5] = 9;
$b[10] = 11;
$result = count($b);
// $result == 3
$result = count(null);
// $result == 0
$result = count(false);
// $result == 1
?>
Example #2
Recursive count(3) example
<?php
$food = array('fruits' => array('orange', 'banana', 'apple'),
'veggie' => array('carrot', 'collard', 'pea'));
// recursive count
echo count($food, COUNT_RECURSIVE); // output 8
// normal count
echo count($food); // output 2
?>
