MySql仅在php

Question

我有这个PHP代码：

$queryGO = "SELECT * from (SELECT g.go as GO, a.gen as Gen, g.descr as Description 
                            FROM geneOntology g, $tabla a where g.go=a.go) resultado 
                            WHERE resultado.go = '$go'";

$result = mysql_query($queryGO, $db);
$items = mysql_affected_rows($db);
$row = mysql_fetch_array($result);

它构造了我这个查询：

SELECT * from ( SELECT g.go as GO, a.gen as Gen, g.descr as Description
FROM geneOntology g, goHuman a where g.go=a.go) resultado 
WHERE resultado.go = 'GO:0000012'

在PHP中，它只返回1个项目（和行）但是如果我直接在终端中执行查询，它会抛出15个寄存器：

+------------+--------+----------------------------+
| GO         | Gen    | Description                |
+------------+--------+----------------------------+
| GO:0000012 | APLF   | single strand break repair |
| GO:0000012 | APTX   | single strand break repair |
| GO:0000012 | E9PIP4 | single strand break repair |
| GO:0000012 | E9PJ82 | single strand break repair |
| GO:0000012 | E9PLZ0 | single strand break repair |
| GO:0000012 | E9PP57 | single strand break repair |
| GO:0000012 | E9PQ18 | single strand break repair |
| GO:0000012 | H0YEW9 | single strand break repair |
| GO:0000012 | LIG4   | single strand break repair |
| GO:0000012 | M0R2N6 | single strand break repair |
| GO:0000012 | Q6ZNB5 | single strand break repair |
| GO:0000012 | SIRT1  | single strand break repair |
| GO:0000012 | TDP1   | single strand break repair |
| GO:0000012 | TNP1   | single strand break repair |
| GO:0000012 | XRCC1  | single strand break repair |
+------------+--------+----------------------------+
15 rows in set (0,04 sec)

我看不出发生了什么。实际上，我在其他php动作中有类似的代码，它执行de query ok ...你能帮帮我吗？

提前致谢！问候。

Answer 1

使用while循环遍历返回，只返回一行：

while($row = mysql_fetch_array($result)){
   print_r($row);
}

请停止使用mysql_ *函数。这些扩展已在PHP 7中删除。了解PDO和MySQLi的预处理语句并考虑使用PDO，这非常简单。
