我有一个带有列的数据库" regId"在一个表用户 我想要做的是选择所有行,但只选择该列(SELECT regId FROM users)
然而,在PHP中,我希望将其作为
数组("第一行ID","第二行ID"等等)
我正在使用Google云消息传递构建应用,并且需要注册ID,例如"数组("某些","其他内容")
这是我的代码
<?php
session_start();
require_once("global.php");
$qry = "SELECT `regId` FROM `users` WHERE regId IS NOT NULL"; //Here's where the IDs are
$fetchQry = mysqli_query($connection, $qry);
// Replace with the real server API key from Google APIs
$apiKey = "/////";
// Replace with the real client registration IDs
$registrationIDs = array("","","",""); //heres how they need the IDs
// Message to be sent
$message = "somethinnnnnn";
// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registrationIDs,
'data' => array( "message" => $message ),
);
$headers = array(
'Authorization: key=' . $apiKey,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the URL, number of POST vars, POST data
curl_setopt( $ch, CURLOPT_URL, $url);
curl_setopt( $ch, CURLOPT_POST, true);
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true);
//curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// curl_setopt($ch, CURLOPT_POST, true);
// curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode( $fields));
// Execute post
$result = curl_exec($ch);
// Close connection
curl_close($ch);
echo $result;
//print_r($result);
//var_dump($result);
?>
我检查了类似的问题,他们都使用了一个while循环,例如
$rows = [];
while($row = mysqli_fetch_array($result))
{
$rows[] = $row;
}
但是,如果我将$ registrationIDs变量设置为$ rows或array($ rows),则它不起作用! (甚至回应他们并没有显示数据)

我最终还是把它弄出来了。感谢Create PHP array from MySQL column
这就是我的所作所为:
$column = array();
while($row = mysqli_fetch_array($result)){
$column[] = $row['regId'];
//Edited - added semicolon at the End of line.1st and 4th(prev) line
}
我之前做过尝试过但是它最初是mysql而不是mysqli !! 然后我还将$ registrationIDs变量设置为$ column

试试这个:
NSArray *words = [texfield.text componentsSeparatedByString:@" "];
int index = [words indexOfObject:@"string"];
看看它是否可行。
