Tworzenie warunku w jednej lini przy pomocy petli Opcje

[rad11]

Mając taka talice:

[PHP] pobierz, plaintext 
array(5) {
  [0]=>
  array(3) {
    ["where"]=>
    string(7) "a_price"
    ["condition"]=>
    string(2) ">="
    ["match"]=>
    int(123213)
  }
  [1]=>
  array(3) {
    ["where"]=>
    string(7) "a_price"
    ["condition"]=>
    string(2) "<="
    ["match"]=>
    int(123)
  }
  [2]=>
  array(3) {
    ["where"]=>
    string(7) "a_price"
    ["condition"]=>
    string(1) ">"
    ["match"]=>
    int(5466)
  }
  [3]=>
  array(3) {
    ["where"]=>
    string(7) "a_price"
    ["condition"]=>
    string(1) "="
    ["match"]=>
    int(87697)
  }
  [4]=>
  array(3) {
    ["where"]=>
    string(7) "a_price"
    ["condition"]=>
    string(1) "<"
    ["match"]=>
    int(14134)
  }
}
 
[PHP] pobierz, plaintext 

Czy jest mozliwe utworzenie przy uzyciu pętli z tej tablicy warunku w jednej linit tzn:

[PHP] pobierz, plaintext 
if(a_price < 14134 && a_price == 87697 && a_price > 5466 && a_price <= 123 && a_price >= 123213){
 
}

A jeżeli będę chciął w fuckji dodać opcje && lub || ?

Niestety musiałem sobie poradzić przy pomocy

[PHP] pobierz, plaintext 
 eval() 
[PHP] pobierz, plaintext 

Jak by ktoś potrzebował:

[PHP] pobierz, plaintext 
public function getWhere() {
        $this->condition = array();
        foreach ($this->where as $whereIndex => $whereValue) {
            if ($whereIndex == (count($this->where) - 1)) {
                unset($this->where[$whereIndex]["mode"]);
            }
            $this->mode = "";
            switch (strtolower($whereValue['condition'])):
                case "in":
                    foreach ($whereValue['match'] as $matchIndex => $matchValue) {
                        $this->conditionIn[] = "\$dataValue['{$whereValue['where']}'] == {$matchValue}";
                    }
                    if (isset($this->where[$whereIndex]['mode'])) {
                        $this->mode = (trim(strtolower($this->where[$whereIndex]['mode'])) == "or") ? ' ||' : ' &&';
                    }
                    $this->condition[] = implode(' || ', $this->conditionIn) . " " . $this->mode;
 
                    break;
                case "like":
                    $this->condition[] = $this->getLike($whereIndex);
                    break;
                case "=":
                    $this->condition[] = $this->getEqual($whereIndex);
                    break;
                case "<":
                    $this->condition[] = $this->getLower($whereIndex);
                    break;
                case ">":
                    $this->condition[] = $this->getGrather($whereIndex);
                    break;
                case ">=":
                    $this->condition[] = $this->getGratherEqual($whereIndex);
                    break;
                case "<=":
                    $this->condition[] = $this->getLowerEqual($whereIndex);
                    break;
                case ">=<":
                    $this->condition[] = $this->getBetweenEqual($whereIndex);
                    break;
                case "><":
                    $this->condition[] = $this->getBetweenWithOutEqual($whereIndex);
                    break;
            endswitch;
        }
        $this->condition = implode(" ", $this->condition);
        foreach ($this->tData as $dataIndex => $dataValue) {
            eval("\$evalCondition = $this->condition;");
            if ($evalCondition) {
                $this->data[] = $dataValue;
            }
        }
        return $this;
    }
[PHP] pobierz, plaintext 

Przykładowa metoda z eval:

[PHP] pobierz, plaintext 
public function getLike($index) {
 
        if (isset($this->where[$index]['mode'])) {
            $this->mode = (trim(strtolower($this->where[$index]['mode'])) == "or") ? ' ||' : ' &&';
        }
 
        return "strpos((string)\$dataValue['{$this->where[$index]['where']}'], (string){$this->where[$index]['match']})";
    }
