PHP:在foreach循环中连接一个字符串 [英] PHP: Concat a string in a foreach loop

问题描述

如何为每个循环在a内连接一个字符串?我在下面做的事情可以在没有循环的情况下正常运行，但是有没有一种方法可以在不结束$body[{{body}}]并重新启动的情况下将循环放入其中?

How can I concat a string inside a for each loop? What I'm doing below works ok without the loop, but is there a way I can put the loop in there without ending the $body[{{body}}] and starting it again?

$carrier = array (
    'SAS' => array('alias' => 'sas', 'name' => 'SAS'),
    'British Airways' => array('alias' => 'british_airways', 'name' => 'British Airways')
);

$body['{{body}}'] = '';

$body['{{body}}'] .= 'Line one'.

    foreach ($carrier as $key=>$value) {
        '<option value='.$value['alias'].'>'.$value['name'].'</option>'.;
    }

'Line two'.
'Line three'.
'Line four';

print_r($body);

推荐答案

尝试一下-您必须将foreach循环中生成的每一行连接起来.

Try this - you have to concatenate each line generated in the foreach loop.

$carrier = array (
    'SAS' => array('alias' => 'sas', 'name' => 'SAS'),
    'British Airways' => array('alias' => 'british_airways', 'name' => 'British Airways')
);

$body['{{body}}'] = 'Line one';

foreach ($carrier as $key=>$value) {
    $body['{{body}}'] .= '<option value=' . $value['alias'] . '>' . $value['name'] . '</option>';
}

$body['{{body}}'] .= 'Line two';
$body['{{body}}'] .= 'Line three';
$body['{{body}}'] .= 'Line four';

print_r($body);
