得到的變量內容

Question

我想學習PHP和過這個問題迷迷糊糊的我的數組 有壞鍵我有這個功能

public function pdf_read_root() 
{ 
    $this->root = $this->pdf_resolve_object($this->c, $this->pdf_find_root()); 

} 

但$this->root將返回錯誤的值，我怎麼得到個別內容$this->c & $this->pdf_find_root看什麼在使用pdf_resolve_object

Answer 1

public function pdf_read_root() 
{ 

    $this->root = $this->pdf_resolve_object($this->c, $this->pdf_find_root()); 
    echo "<pre>"; 
    echo "<br> Value of member variable c is: ". print_r($this->c, true); 
    echo "<br> Value of method pdf_find_root() is: ". print_r($this->pdf_find_root(),true); 
    echo "<br> Value of member variable root is: ". print_r($this->root, true); 
    echo "</pre>"; 

}
