意外的T_DOUBLE_ARROW當提到一個數組時

Question

我認爲它是因爲我沒有正確引用數組。我是PHP新手，所以我遇到了這個錯誤。

在此行中$this->fields['id'] => &$doc->id;

碼是用於參考給定：

<?php 

class Zoho{ 
    public $fields; 

    public function __construct(){ 
    $this->fields = array(

    // 'content' => "@/wamp/apps/researchportal/tmp/a.doc", 
     'apikey' => $this->api_key, 
     'output' => $this->output, 
    // 'id' => time(), 
    // 'filename' => $usr_bin.'_!@#$%^&^%$#@'.$usr_doc, 
    // 'format' => $ext, 
     'saveurl' => $this->save_url = $save_url, 
     'mode' => $this->mode 
    ); 

    } 

    public function viewDocument(&$doc) { 

    $this->fields['id'] => &$doc->id; 
    $this->fields['filename'] => &$doc->doc_name; 
    $this->fields['format'] => &$doc->doc_ext; 
    $this->fields['mode']='view'; 
    $this->fields['content']='@'.&$doc->path; 

    } 


} 

    $document = new Document('C:/wamp/apps/researchportal/tmp/qubee.doc'); 
    $zoho_s = new Zoho('http://133.223.121.12/researchportal/common/save.php'); 
    $zoho->viewDocument(); 

?> 

Answer 1

public function viewDocument(&$doc) { 

    $this->fields['id'] => &$doc->id; 
    $this->fields['filename'] => &$doc->doc_name; 
    $this->fields['format'] => &$doc->doc_ext; 
    $this->fields['content'] = '@'.&$doc->path; 

應該是：

public function viewDocument(&$doc) { 

    $this->fields['id'] = $doc->id; 
    $this->fields['filename'] = $doc->doc_name; 
    $this->fields['format'] = $doc->doc_ext; 
    $this->fields['content'] = '@' . $doc->path;
