Refer to the official document, first obtain the accesstoken, and then call the official url to pass in the accessed page path and query parameters to generate URLScheme

<?php
$appId = 'your_appid'; // 替换为你的小程序的AppID
$appSecret = 'your_appsecret'; // 替换为你的小程序的AppSecret

$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appId&secret=$appSecret";

$response = file_get_contents($url);
$data = json_decode($response, true);
$accessToken = $data['access_token'];

echo $accessToken;
?>

<?php
$accessToken = "YOUR_ACCESS_TOKEN";

$url = "https://api.weixin.qq.com/wxa/generatescheme?access_token=" . $accessToken;

$data = array(
    "jump_wxa" => array(
        "path" => "/pages/publishHomework/publishHomework",
        "query" => "",
        "env_version" => "release"
    ),
    "is_expire" => true,
    "expire_type" => 1,
    "expire_interval" => 1
);

$dataJSON = json_encode($data);

$options = array(
    "http" => array(
        "header" => "Content-Type: application/json",
        "method" => "POST",
        "content" => $dataJSON
    )
);

$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);

if ($response === false) {
    // handle error
} else {
    $responseData = json_decode($response, true);
    
    if ($responseData["errcode"] === 0) {
        $openlink = $responseData["openlink"];
        // handle success, use $openlink
    } else {
        $errMsg = $responseData["errmsg"];
        // handle error, use $errMsg
    }
}
