在php中通过foreach循环从数组中获取值的问题

Question

c.corridor_plan_id

我从这段代码得到的结果是

<?php
$v = array();
$text_attributes = array();
$i = 0;
foreach($input_text as $key => $value):
    $i++;
    $v[$i]=$value;
    $text_attributes[$key] = explode("\t", $v[$i]);
endforeach;
echo "<pre>";
print_r($text_attributes);
die();
?>

）

现在我想根据数组的索引值显示结果。 意味着如果0索引包含文本而不是它将显示文本框中最后一个索引的值，并且如果第一个索引包含图像的值，则它显示第二个索引上的图像值。但是这个循环总是显示我的最后一个值阵列。 E，G

请有人帮我解决这个问题.. 谢谢高级

Answer 1

在$ text_attributes [$ key] = explode（＆＃34; \ t＆＃34;，$ v [$ i]）之后，在你的foreach循环中

;线。试试这个

if($text_attributes[$key][0]=='images')
{
    echo $text_attributes[$key][3];

}
if($text_attributes[$key][0]=='text')
{
    echo $text_attributes[$key][2];
}

Answer 2

我从你的结果中编写了一个代码，希望这对你有帮助。

$textAttributes = array(0 => array(0 => 'text',
        1 => 'Composition',
        2 => '1text1',
        3 => 'Test saf af saf'), 1 => array(0 => 'image',
        1 => 'c://xampp/htdocs/clickcue/application/app/webroot/files/ae_templates/rendered_templates/192/710/',
        2 => 'i1.jpg',
        3 => 'Chrysanthemum - Copy - Copy.jpg'));

foreach ($textAttributes as $textAttribute) {
    if ($textAttribute[0] == 'text') {
        echo end($textAttribute) . '<br/>';
    } else if ($textAttribute[0] == 'image') {
        echo $textAttribute[2] . '<br/>';
    }
}
