Question

我试图从cURL响应数组中获取数值。但无法做到这一点。我使用此代码

<?php


?>

<?php get_header(); ?>

<!-- Start body -->

    <body <?php body_class(); ?>>

<!-- Hier geht der Wrapper auf-->                                              
<div class="wrapper">

<!-- Get Logo -->
<?php get_template_part( 'logo' ); ?>

    <div class="clear"></div>

<!-- Wordpress verbieten, <p>-Tags zu setzen -->  

<?php remove_filter ('the_content', 'wpautop'); ?>



    <!-- T H E   L O O P -->  


    <?php if ( have_posts() ): ?>

    <?php while ( have_posts() ) : the_post(); ?>

    <div class="article-content" id="post-<?php the_ID(); ?>">

    <div class="article-thumb">

    <?php the_content(); ?>
    <div class="theid"><?php the_ID(); ?></div>

    <?php if (in_category( "28" )){
        echo '<a href="';
        echo '#';
        echo '" target="_blank"> link</a>';

        }

    else { echo 'Hi!'; ?>


    <!-- Close article-thumb -->
        </div>

    <!-- Close article-content -->

    </div>

    <?php endwhile; ?>

    <?php endif; ?>


    <!-- /T H E   L O O P -->  



<!-- Clear -->    

<div class="clear"></div>



<?php else: ?>
<h2>No posts to display</h2>
<?php endif; ?>
<?php wp_reset_query(); ?>


<!-- bottomnav -->

<div class="bottomnav"><a class="super next"><?php posts_nav_link(' / ','Zurück','Weitere Projekte'); ?></a></div>



<!-- Infinite Scroll -->

<script type="text/javascript">
$('.wrapper').infinitescroll({
    loading: {
        finished: undefined,
        finishedMsg: "End.",
        img: "http://www.injuvik.de/wp-content/themes/injuvik/img/pfeilnachunten.png",
        msg: null,
        msgText: "Loading..",
        selector: null,
        speed: 'fast',
        start: undefined

        },
    navSelector: "div.bottomnav",
    nextSelector: "div.bottomnav a:last", 
    itemSelector: "div.wrapper div.article-content",
    animate: false
    });
</script>



</div>

<!-- toggle class on click -->

<script>
$('body').on('click', 'div.article-content', function(){
$( this ).toggleClass( "bigger" );
});
</script>



<?php get_footer(); ?>

它打印此我们的新发票ID是：[{-10191}] 在页面上。现在我想从数组中获取10191。我尝试了这个，但失败了。

var ar_val=[]; 
    $("form").find("[id$='PFtxtname']").each(function () {

            var txtv =  $(this).val().trim();  
    ar_val.push(txtv);    
                });

我如何检索数值？

Answer 1

如果$returndata与字符串

相似

将此信息放在curl_exec：

之后

<?php

$urltopost = "http://www.xxxx.yyy.com/zzz.php";
$ch = curl_init ($urltopost);
curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$returndata = curl_exec ($ch);
//$returndata = 'Our new Invoice (ID) is: [{-10191}]';
preg_match_all("/\{([^\]]*)\}/", $returndata, $matches);
$invoiceID = intval(ltrim($matches[1][0], '-'));
print_r($invoiceID);
