我有一个工作的SQL查询,我试图在一个小的PHP脚本中使用,但得到Parse错误,尝试了很多变化。希望你能帮忙。最终结果将是具有“日期”和“通道号”的两个字段形式,然后给出给定日期的“通道”行数的结果计数。抱歉相当新的PHP / SQL,谢谢。
<?php
// Connect to MSSQL and select the database
$link = mssql_connect('localhost', 'root', '', 'jm_db');
mssql_select_db('jm_db');
// Select all our records from a table
$mysql_query = mssql_query ('SELECT COUNT(*) FROM asterisk_cdr
WHERE calldate LIKE '%2014-10-11%'
AND channel LIKE '%SIP/4546975289%');
echo $sql;
?>
我重新完成了代码,但得到'警告:mysql_fetch_array()期望参数1是资源'和未定义的变量。
<?php
// Create connection
$mysqli = new mysqli($localhost, $root, $jm_db);
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$sql = ("SELECT COUNT(*) FROM asterisk_cdr
WHERE calldate LIKE '%2014-10-11%'
AND channel LIKE '%SIP/4546975289%'");
$results= array();
while ($result = mysql_fetch_array($sql)) {
$results[]= $result;
}
foreach($results as $result){
echo $result['calldate'] . " " . $result['channel'];
}
?>

你错过了一个引用(Stack的语法高亮显示你),但它应该用一个开头的双引号替换,并以相同的结尾。您不能使用所有单引号。
我用双倍替换了开头的单引号,以及匹配的结束双引号。
$mysql_query = mssql_query ("SELECT COUNT(*) FROM asterisk_cdr
WHERE calldate LIKE '%2014-10-11%'
AND channel LIKE '%SIP/4546975289%'");
作为旁注,你回应了错误的变量。
然而,这不是你如何回应结果,而是循环。
类似于,并将Fieldname
替换为您要使用的那个:
while ($row = mssql_fetch_assoc($mysql_query)) {
print $row['Fieldname'] . "\n";
}
或使用mssql_fetch_array()
您也可以使用:
$results= array();
while ($result = mssql_fetch_array($mysql_query)) {
$results[]= $result;
}
foreach($results as $result){
echo $result['calldate'] . " " . $result['channel'];
}

这是PDO的一个简单示例
<?php
try {
$dns = 'mysql:host=localhost;dbname=jm_db';
$user = 'root';
$pass = '';
$options = array(
PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8",
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
);
$cnx = new PDO( $dns, $user, $pass, $options );
$select = $cnx->query("SELECT COUNT(*) as count FROM asterisk_cdr WHERE calldate LIKE '%2014-10-11%' AND channel LIKE '%SIP/4546975289%'");
$select->setFetchMode(PDO::FETCH_OBJ);
while( $row = $select->fetch() )
{
echo '<h1>', $row->count , '</h1>';
}
} catch ( Exception $e ) {
echo "Connect failed : ", $e->getMessage();
die();
}

$mysqli = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($mysqli->connect_error) {
die("Connection failed: " . $mysqli->connect_error);
}
$mysql_query = mysqli ("SELECT COUNT(*) FROM asterisk_cdr WHERE calldate LIKE '%2014-10-11%' AND channel LIKE '%SIP/4546975289%'");
while ($row = mysql_fetch_array($mysql_query, MYSQL_ASSOC)) {
