PHP：回声数组只返回字数组而不是其内容 [英] PHP: echoing array only returns the word array instead of its content

问题描述

我很新的PHP，希望你能帮助我。

我从SQL获取一些数据，并尝试创建一个我想在页面上回显的数组。

当我回应下面的结果（ $ output ）时，只返回单词array我试图添加到它的项目。

是否有人能告诉我我在做什么错误，并给我一个简短的解释？

  $ c =; 
 $ i = 0; 
 $ arr = array（）; 
 $ output =''
 foreach（$ objNames->名称为$ names）{
 $ c =< img src ='images / photos / photo_。 str_replace（，_，$ names->成员）。 .pngalt ='class ='clickable flagLink trackHC'/>& nbsp; 。 $ names->成员。 & nbsp;& nbsp;; 
 array_push（$ arr，$ c）; 
 $ i ++; 
 
 if（$ i！= 0）{
 $ output = $ arr; 
} 
 
 
< div id =output><？php echo $ output; ？>< / DIV> 
  

非常感谢您的帮助，Mike。

解决方案

你不能只回显数组。

例如通过它foreach：

  $ c =; 
 $ i = 0; 
 $ arr = array（）; 
 $ output =''
 foreach（$ objNames->名称为$ names）{
 $ c =< img src ='images / photos / photo_。 str_replace（，_，$ names->成员）。 .pngalt ='class ='clickable flagLink trackHC'/>& nbsp; 。 $ names->成员。 & nbsp;& nbsp;; 
 array_push（$ arr，$ c）; 
 $ i ++; 
 
 if（$ i！= 0）{
 $ output = $ arr; 
} 
 
 foreach（$ output as $ row）{
？> 
< div id =output><？php echo $ row; ？>< / DIV> 
 <？php 
} 
  

这应该适合您！ p>

I am very new to PHP and hope you can help me with this.

I am fetching some data from SQL and try to create an array that I want to echo on a page.

When I echo the result from the following ($output) then this only returns the word "array" insteaed of the items that I am trying to add to it.

Can someone tell me what I am doing wrong here and provide me a short explanation as well ?

$c = "";
$i = 0;
$arr = array();
$output = ''
foreach ($objNames->names as $names) {
    $c = "<img src='images/photos/photo_" . str_replace(" ", "_", $names->member) . ".png' alt='' class='clickable flagLink trackHC' />&nbsp;" . $names->member . " &nbsp;&nbsp;";
    array_push($arr, $c);
    $i++;
}
if($i != 0) {
    $output = $arr;
}


<div id="output"><?php echo $output; ?></div>

Many thanks for any help, Mike.

解决方案

You cant just echo arrays.

You have to loop through it with a foreach for example:

$c = "";
$i = 0;
$arr = array();
$output = ''
foreach ($objNames->names as $names) {
    $c = "<img src='images/photos/photo_" . str_replace(" ", "_", $names->member) . ".png' alt='' class='clickable flagLink trackHC' />&nbsp;" . $names->member . " &nbsp;&nbsp;";
    array_push($arr, $c);
    $i++;
}
if($i != 0) {
    $output = $arr;
}

foreach($output as $row) {
?>
    <div id="output"><?php echo $row; ?></div>
<?php
}

This should work for you!
