PHP、XAMPP、SQL SERVER 2012 中 array_push() 的等效 sqlsrv_

Question

sqlsrv_ 中的array_push() 是否有等效代码？喜欢sqlsrv_array_push()。我不确定它是否有，我还没有阅读关于该代码的文档。有替代方案吗？

我尝试重新编码，这就是我目前所得到的。

编辑：添加 conn.php

<?php
$serverName = "XXXXXX\XXXXXX";
$connectionInfo = array( "Database"=>"XXXXXX", "UID"=>"XXXXXX", "PWD"=>"XXXXXX");
$conn = sqlsrv_connect( $serverName, $connectionInfo);

if( $conn ) {
     echo "Connection established.<br />";
}else{
     echo "Connection could not be established.<br />";
     die( print_r( sqlsrv_errors(), true));
}
?> 

编辑：添加$and

$and = 'AND YEAR(date) = '.$year;
$months = array();
$ontime = array();
$late = array();
for( $m = 1; $m <= 12; $m++ ) {
    $sql = "SELECT * FROM CHECKINOUT WHERE MONTH(CHECKTIME) = '$m' AND CHECKTYPE = 'I' $and";
    $oquery = $conn->query($sql);
    array_push($ontime, sqlsrv_num_rows($oquery));

    $sql = "SELECT * FROM CHECKINOUT WHERE MONTH(CHECKTIME) = '$m' AND CHECKTYPE = 'O' $and";
    $lquery = $conn->query($sql);
    array_push($late, sqlsrv_num_rows($lquery));

    $num = str_pad( $m, 2, 0, STR_PAD_LEFT );
    $month =  date('M', mktime(0, 0, 0, $m, 1));
    array_push($months, $month);
}

这是我遇到的错误。

警告：sqlsrv_num_rows() 期望参数 1 是资源，布尔值在 C:\xampp\htdocs\path\tofile\home.php 第 198 行给出

说明：

如果我理解您的逻辑，您需要将$conn->query($sql); 替换为sqlsrv_query() 调用。函数 sqlsrv_? 是 SQL Server 的 PHP 驱动程序的一部分，不是面向对象的。

示例：

下一个示例基于您的代码，可能有助于获得您的预期结果：

<?php
$and = 'AND YEAR(CHECKTIME) = '.$year;
$months = array();
$ontime = array();
$late = array();
for( $m = 1; $m <= 12; $m++ ) {
    $sql = "SELECT * FROM CHECKINOUT WHERE MONTH(CHECKTIME) = '$m' AND CHECKTYPE = 'I' $and";
    $oquery = sqlsrv_query($conn, $sql, array(), array("Scrollable" => SQLSRV_CURSOR_KEYSET));
    if ($oquery === false) {
        echo "Error (sqlsrv_query): ".print_r(sqlsrv_errors(), true);
        exit;
    }   
    array_push($ontime, sqlsrv_num_rows($oquery));


    $sql = "SELECT * FROM CHECKINOUT WHERE MONTH(CHECKTIME) = '$m' AND CHECKTYPE = 'O' $and";
    $lquery = sqlsrv_query($conn, $sql, array(), array("Scrollable" => SQLSRV_CURSOR_KEYSET));
    if ($lquery === false) {
        echo "Error (sqlsrv_query): ".print_r(sqlsrv_errors(), true);
        exit;
    }   
    array_push($late, sqlsrv_num_rows($lquery));

    $num = str_pad( $m, 2, 0, STR_PAD_LEFT );
    $month =  date('M', mktime(0, 0, 0, $m, 1));
    array_push($months, $month);
?>

注意事项：

您也可以考虑使用参数化查询：

<?php
$y = 2019;
$months = array();
$ontime = array();
$late = array();
for( $m = 1; $m <= 12; $m++ ) {
    $sql = "SELECT * FROM CHECKINOUT WHERE YEAR(CHECKTIME) = ? AND MONTH(CHECKTIME) = ? AND CHECKTYPE = 'I'";
    $oquery = sqlsrv_query($conn, $sql, array(&$y, &$m), array("Scrollable" => SQLSRV_CURSOR_KEYSET));
    if ($oquery === false) {
        echo "Error (sqlsrv_query): ".print_r(sqlsrv_errors(), true);
        exit;
    }   
    array_push($ontime, sqlsrv_num_rows($oquery));

    $sql = "SELECT * FROM CHECKINOUT WHERE YEAR(CHECKTIME) = ? AND MONTH(CHECKTIME) = ? AND CHECKTYPE = 'O'";
    $lquery = sqlsrv_query($conn, $sql, array(&$y, &$m), array("Scrollable" => SQLSRV_CURSOR_KEYSET));
    if ($lquery === false) {
        echo "Error (sqlsrv_query): ".print_r(sqlsrv_errors(), true);
        exit;
    }   
    array_push($late, sqlsrv_num_rows($lquery));

    $num = str_pad( $m, 2, 0, STR_PAD_LEFT );
    $month =  date('M', mktime(0, 0, 0, $m, 1));
    array_push($months, $month);
}
?>
