我试图在两个文件之间传输数据。
sender.php 代码(使用POST方法发送数组的文件)
$url = 'http://localhost/receiver.php';
$myvars = array("one","two","three")
$post_elements = array('myvars'=>$myvars);
$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, 1);
curl_setopt( $ch, CURLOPT_POSTFIELDS, $post_elements);
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt( $ch, CURLOPT_HEADER, 0);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec( $ch );
echo "$response";
receiver.php 代码(从sender.php文件接收数组的文件,然后获取数组的每个元素并回显它,并将其放入文件saved.txt。
echo $_POST($myvars); // To test the output of the received data.
foreach($myvars as $item) {
if (!empty($item)) {
echo $item."<br>";
$myfile = file_put_contents('Saved.txt', (" Name: ". ($_POST["$item"])) . PHP_EOL , FILE_APPEND);
}
}
数组没有被转移到receiver.php或者我没有捕获它。在文档输出中,我只代替变量$ item而不是数组的每个元素。
编辑: 在接收文件中添加了以下代码,以便从内部获取数组元素,但我得到的只是阵列打印出来:
foreach( $_POST as $stuff ) {
if( is_array( $stuff ) ) {
foreach( $stuff as $thing ) {
echo $thing;
}
} else {
echo $stuff;
}
}
通过在接收文件上添加以下内容:
echo "<pre>";
print_r($_POST);
echo "</pre>";
我得到以下内容:
Array
(
[myvars] => Array
)

尝试序列化数组,因为它总能帮助我:
$url = 'http://localhost/receiver.php';
$myvars = array("one","two","three");
$myvars_post=join(" ",$myvars);
$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, 1);
curl_setopt( $ch, CURLOPT_POSTFIELDS, "array=".urldecode($myvars_post));
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt( $ch, CURLOPT_HEADER, 0);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec( $ch );
echo "$response";
并在receiver.php中使用:
print_r($_POST);

好的,上面评论中讨论的底线导致了这个结果:
发送部分:
<?php
$url = 'http://localhost/out.php';
$myvars = array("one","two","three");
$post_elements = array('myvars'=>$myvars);
$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, 1);
curl_setopt( $ch, CURLOPT_POSTFIELDS, http_build_query($post_elements));
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt( $ch, CURLOPT_HEADER, 0);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec( $ch );
print_r($response);
接收部分:
<?php
print_r($_POST);
发送方的输出是:
Array ( [myvars] => Array ( [0] => one [1] => two [2] => three ) )
基本上说你可以简单地在接收端使用$_POST['myvars']
,它将完全保存你想要传输的标量数组。
