Question

这是我的代码，我正在尝试将图像内容编码为base64，但我最终将URL作为base64字符串结束。

最后，我将图像作为数组从我需要的API转换为Base64以存储在本地数据库中。

这是基于Gravity Forms API，Wordpress，PHP，mySQL，（LAMP）等。

<?php
$images = array();
    $body = array();
    $imagesDecoded = array();
    $imgUrls = array(
                    '1' => 'bg.jpg',
                    '2' => 'meeting.jpg',
                    '3' => 'testimonial.jpg',
                    '4' => 'works.jpg',
                );

$imgUrls = array_map(function($el) {
    return 'http://orlandojoes.co.uk/rimos/images/' . $el;
}, $imgUrls);

print'<pre>';
print_r($imgUrls);
print'</pre>';

foreach ($imgUrls as $image) {
    $data = file_get_contents($imgUrls);
    $data = base64_encode($imgUrls);
    array_push($body, $data);

}

print '<pre>';
print_r ($body);
print '<pre>';

foreach ($body as $bodyimage) {
    $dataDec = base64_decode($bodyimage);
    array_push($imagesDecoded, $dataDec);
}
print '<pre>';
print_r ($imagesDecoded);
print '<pre>';

这是我现在运行此代码时的输出：

Array
(
    [ptSignature] => http://orlandojoes.co.uk/rimos/images/bg.jpg
    [pSignature] => http://orlandojoes.co.uk/rimos/images/meeting.jpg
    [witness1Signature] => http://orlandojoes.co.uk/rimos/images/testimonial.jpg
    [witness2Signature] => http://orlandojoes.co.uk/rimos/images/works.jpg
)
Array

    [1] => http://orlandojoes.co.uk/rimos/images/meeting.jpg

    [3] => http://orlandojoes.co.uk/rimos/images/works.jpg
)

您的代码中有两个错误。

$data = file_get_contents($imgUrls); // This is an array of URLs
$data = base64_encode($imgUrls); // You encode the URLs here!

应该是：

$data = file_get_contents($image); // $image instead of $imgUrls
$data = base64_encode($data); // $data instead of $imgUrls

或者简单地说：

$data = base64_encode(file_get_contents($image));

旁注，您的代码中不需要array_push()，通常只有在您想要同时推送多个项目时才需要它。因此，您可以将其更改为：

$body[] = $data;

将PHP数组中的URL编码为Base64
