PHP while循环内存错误

Question

我收到了这个错误：

  

致命错误：允许的内存大小为134217728字节已用尽（尝试分配＆gt; 32字节）在路径/ / 1phpquery.php上＆gt;第24行

第24行

  

while（$ r = $ mysqli-＆gt; query（$ query））{

完整的代码是：

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

$instr = "CCBOT";
require("dbconnect.php");

$query = 'SELECT LgSpecNet, SmSpecNet, CommNet FROM cot WHERE Ticker = "$instr" LIMIT 5';

if ($result = $mysqli->query($query)) {

$table = array();

$table['cols'] = array(
array('label' => 'Large Spec Net', 'type' => 'number'),
array('label' => 'Small Spec Net', 'type' => 'number'),
array('label' => 'Commercial Net', 'type' => 'number')
);

$rows = array();

while ($r = $mysqli->query($query)) { 
$temp = array();

$ra = $r->fetch_assoc();    

$temp[] = array('v' => (int) $ra['LgSpecNet']);
$temp[] = array('v' => (int) $ra['SmSpecNet']);
$temp[] = array('v' => (int) $ra['CommNet']);

$rows[] = array('c' => $temp);
}

$result->free();

$table['rows'] = $rows;

$jsonTable = json_encode($table);

echo $jsonTable;

}

$mysqli->close();

?>

Answer 1

您无休止地重新运行查询。变化

while ($r = $mysqli->query($query))

要

while ($ra = $result->fetch_assoc())

删除该行：

$ra = $r->fetch_assoc();
