Question

array_push()中的sqlsrv_是否有等效代码？像sqlsrv_array_push()。我不确定它是否有一个，我还没有阅读有关该代码的文档。有其他选择吗？

我试图重新编码，这就是到目前为止。

编辑：添加了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：添加了$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);
}

这是我得到的错误。

警告：sqlsrv_num_rows（）希望参数1是资源，在198行的C：\ xampp \ htdocs \ path \ tofile \ home.php中给出布尔值

说明：

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

示例：

下一个示例基于您的代码，可能有助于获得预期的结果：

<?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);
?>

注释：

您还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);
}
?>

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