我有一个php acript,其目标是以json格式从数据库中获取数据,以便在Android应用程序上显示所述数据。
我在服务器上运行脚本,但它不返回任何内容,没有文本,没有任何内容,只是一个空白页面。我甚至在看了很多文件之后都不知道为什么。
剧本:
<?php
$serverName = "mssql3.gear.host";
/* Get UID and PWD from application-specific files. */
$uid = '-----------';
$pwd = '-----------';
$connectionInfo = array( "UID"=>$uid,
"PWD"=>$pwd,
"Database"=>"programaplo");
/* Connect using SQL Server Authentication. */
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false )
{
echo "Unable to connect.</br>";
die( print_r( sqlsrv_errors(), true));
}
echo 'Connected successfully';
$tsql = "SELECT * FROM Obras";
$stmt = sqlsrv_query($conn, $tsql);
if( $stmt === false ) {
echo "Error in executing query.</br>";
die( print_r( sqlsrv_errors(), true));
}
$json = array();
do {
while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
$json[] = $row;
}
} while ( sqlsrv_next_result($stmt) );
/* Run the tabular results through json_encode() */
/* And ensure numbers don't get cast to trings */
print json_encode($json,<code> JSON_NUMERIC_CHECK</code>);
/* Free statement and connection resources. */
sqlsrv_free_stmt( $stmt);
sqlsrv_close( $conn);
?>

答案 0 :(得分:0)
这条线似乎是罪魁祸首 - 它让你解析错误:
print json_encode($json,<code> JSON_NUMERIC_CHECK</code>);
将其更改为:
print json_encode($json, JSON_NUMERIC_CHECK);
