解析错误:语法错误,意外T_VARIABLE,期望PHP 5.3中的T_STRING

我遇到了这个问题......它说的是“意想不到的T_VARIABLE”。有问题的一行是:

$children[ $i['parent_id'] ][] = array($i['forum_id'], "<option value=\"{$i['forum_id']}\"$selected>  ", "{$i['forum_name']}</option>\n");

我尝试删除$(在$children中),但仍然会导致错误。它说“解析错误:语法错误,意外'['在......”

奇怪的是,这在PHP 5.2中没有问题。但是在PHP 5.3中,出现了问题。

由于我不是一个真正的程序员(只知道一点基本,我主要是设计),我真的对这里发生的事情毫无头绪。任何人都可以提供帮助吗?

这是完整的功能:

function build_forum_jump($html=1, $override=0, $remove_redirects=0)
{
    global $INFO, $DB, $ibforums;
    $last_cat_id = -1;

    if ( $remove_redirects )
    {
        $qe = 'AND f.redirect_on <> 1';
    }
    else
    {
        $qe = '';
    }

    $DB->query("SELECT f.id as forum_id, f.parent_id, f.subwrap, f.sub_can_post, f.name as forum_name, f.position, f.redirect_on, f.read_perms, c.id as cat_id, c.name
                FROM ibf_forums f
                 LEFT JOIN ibf_categories c ON (c.id=f.category)
                WHERE c.state IN (1,2) $qe
                ORDER BY c.position, f.position");


    if ($html == 1) {

        $the_html = "<form onsubmit=\"if(document.jumpmenu.f.value == -1){return false;}\" action='{$ibforums->base_url}act=SF' method='get' name='jumpmenu'>
                     <input type='hidden' name='act' value='SF' />\n<input type='hidden' name='s' value='{$ibforums->session_id}' />

试试这个。我重写了整行,使其更清晰(更具保证性)。

$children[$i['parent_id']][] = array($i['forum_id'], '<option value="'.$i['forum_id'].'"'.$selected.'>  ', $i['forum_name'].'</option>\n');

同样将第1270行从您的pastebin更改为:

$the_html = str_replace('</option><!--fx:'.$idx.'-->', '(+'.count($children[$idx]).' '.$ibforums->lang['fj_subforums'].')</option>', $the_html);

你在找错了地方。

/****** INFINITE SUBFORUMS FIX BEGINS ************/
$the_html .= $this->subforums_addtoform($idx, \$children);
/********** INFINITE FIX - END ************/

应为$children \$children


至于为什么这在PHP 5.2中工作而不在PHP 5.3中,为namespaces引入了'\'字符(例如MyNamespace\SubSpace\Something)。

给出以下代码:

function foo() {
    $children = 'Hello world';
    echo \$children;
}
foo();

在PHP 5.2中,结果如下:

  

警告:输入中出现意外字符:'\'(ASCII = 92)状态=%s在%d行

     

Hello world

在PHP 5.3中:

  

解析错误:语法错误,意外T_VARIABLE,期待%s上%s的T_STRING

在PHP 5.4中:

  

解析错误:语法错误,意外的'$ children'(T_VARIABLE),在%d行上的%s期待标识符(T_STRING)

在WP工作之后我得到了同样的错误,但PHP已经更新,来自以下代码:

if($bgc==""){
    $bgc="#eeeeee";
}else{ \
    $bgc="";
}
$gmp_action = "delete-address";
?>

删除反斜杠修复它。

试试这个:

$children[ $i['parent_id'] ][] = array($i['forum_id'], '<option value="'.$i['forum_id'].'"'.$sub_css.'"'.$selected.'>  ', $i['forum_name'].$is_sub.'</option>'."\n");
