Problem adding operator condition to the string - php

Question

I need to add AND or OR in-between my Query string. My conditions are as follows:
first case:
$array = [
"month" => "October",
"year" => 2020,
"information => "October 2020"
];
In this case, i need
"(MONTH(b.day) = 'October' AND YEAR(b.day) = '2020') OR b.information LIKE '%October 2020%'"
second case:
$array = [
"month" => "October",
"information => "October 2020"
];
In this case, i need
"(MONTH(b.day) = 'October') OR b.information LIKE '%October 2020%'"
I have tried following lines of code but I couldn't fix the AND OR in correctly.
$whereStr = '';
$alias = "b.";
$orCounter = 0;
$andCounter = 0;
$dateMonth = false;
if (array_key_exists('year', $array) && array_key_exists('month', $array)) {
$dateMonth = true;
}
foreach ($array as $key => $value) {
if (0 !== $orCounter) {
$whereStr .= ' OR ';
} elseif ($andCounter > 0 && true === $dateMonth) {
$whereStr .= ' AND ';
}
if ('month' === $key || 'year' === $key) {
++$andCounter;
echo $andCounter;
$whereStr .= strtoupper($key) . '(' . $alias . 'day' . ')';
$whereStr .= "= '$value'";
if ($andCounter === 2) {
++$orCounter;
}
continue;
}
if ('type' === $key) {
$whereStr .= "$alias$key IN ($value)";
continue;
}
$whereStr .= "$alias$key LIKE '%$value%'";
++$orCounter;
}
Can anybody please help me fix this?

Answer 1

just use simple if else conditions why using loop
$where ='';
if(isset($array['month']) && isset($array['year']) && isset($array['information'])){
$where = '(MONTH(b.day) = '".$array['month']."' and YEAR(b.day) = '".$array['year']."' ) or b.information like "%'.$array['information'].'%" ';
}else if(isset($array['month']) && !isset($array['year']) && isset($array['information']))
{
$where = '(MONTH(b.day) = '".$array['month']."' ) or b.information like "%'.$array['information'].'%" ';
}

Answer 2

It's cleaner with arrays:
$AND[] = "`fieldA` = 'Bar'";
$AND[] = "`fieldB` = 'Foo'";
$andString = implode(' AND ',$AND);
$andString is
`fieldA` = 'Bar' AND `fieldB` = 'Foo'
So your code can be
$qq = "SELECT * from foobar WHERE $andString";
