[英]Calling php script using C# (Unity)
我對Unity和PHP都很陌生,我目前正在開發一個項目,我可以使用PHP將MySQL數據庫中的數據解析為Unity。
我最初想嘗試啟用一種方法,用戶可以更改php腳本並使其能夠選擇不同的數據表,但我被告知,在php腳本中列出所有變量並從中調用它可能更安全相應的統一;
Display.php的
$table = mysql_real_escape_string($_GET['table'], $db);
if ($table == "shoes") {
$query = "SELECT * FROM `shoes` ORDER by `price` ASC LIMIT 10";
elseif ($table == "sneakers") {
$query = "SELECT * FROM `sneakers` ORDER by `price` ASC LIMIT 10";
$result = mysql_query($query) or die('Query failed: ' . mysql_error());
$num_results = mysql_num_rows($result);
for($i = 0; $i < $num_results; $i++)
{
$row = mysql_fetch_array($result);
echo $row['shopname'] . "\t" . $row['price'] . "\n";
}
我在調用php並選擇我想要選擇的表時遇到了麻煩,我對此很新,所以如果這對你們來說似乎完全無能,我會道歉。
這是我的Unity腳本;
HSController.cs
void Start()
{
StartCoroutine(GetScores());
}
// remember to use StartCoroutine when calling this function!
IEnumerator PostScores(string name, int score)
{
string hash = Md5Sum(name + score + secretKey);
string post_url = addScoreURL + "name=" + WWW.EscapeURL(name) + "&score=" + score + "&hash=" + hash;
WWW hs_post = new WWW(post_url);
yield return hs_post; // Wait until the download is done
if (hs_post.error != null)
{
print("There was an error posting the high score: " + hs_post.error);
}
}
IEnumerator GetScores()
{
gameObject.guiText.text = "Loading...";
WWW hs_get = new WWW(highscoreURL);
yield return hs_get;
if (hs_get.error != null)
{
print("There was an error getting the high score: " + hs_get.error);
}
else
{
gameObject.guiText.text = hs_get.text; // this is a GUIText that will display the scores in game.
}
}
任何幫助或正確方向上的一點都會很棒!
親切的問候
讓我嘗試將其重寫為一個工作示例:
void Start() {
StartCoroutine(GetData());
}
IEnumerator GetData() {
gameObject.guiText.text = "Loading...";
WWW www = new WWW("http://yoururl.com/yourphp.php?table=shoes"); //GET data is sent via the URL
while(!www.isDone && string.IsNullOrEmpty(www.error)) {
gameObject.guiText.text = "Loading... " + www.Progress.ToString("0%"); //Show progress
yield return null;
}
if(string.IsNullOrEmpty(www.error)) gameObject.guiText.text = www.text;
else Debug.LogWarning(www.error);
}
<?php
//DB connection goes here
if ($_REQUEST['table'] === "shoes") { //I'm using REQUEST instead of GET, so it will work with both GET and POST
$query = "SELECT * FROM `shoes` ORDER by `price` ASC LIMIT 10";
} elseif ($_REQUEST['table'] === "sneakers") {
$query = "SELECT * FROM `sneakers` ORDER by `price` ASC LIMIT 10";
}
$result = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_assoc($result)) {
echo $row['shopname'] . "\t" . $row['price'] . "\n";
}
?>
希望這可以幫助!
