是否有可能宣佈從功能

Question

是分配可以填補一個變量像這樣在PHP中的全局變量：

我有這樣的PHP類：

class Cek_list_wire_rod extends Members_Controller { 
    private $table_generate; 

public function ajax_list() { 
    $record_num = $this->uri->segment($this->uri->total_segments()); 
    $list = $this->cek_list->get_datatables($record_num); 
    $this->table_generate = $list; // Create an array object 

/*.....*/ 
} 

public function generate_pdf_laporan() { 
    echo "<pre>"; 
    print_r ($this->table_generate); //Empty 
} 

對於幫助，它很讚賞

它應該工作得很好，如圖所示here。

<?php class Cek_list_wire_rod { 
    private $table_generate; 

public function ajax_list() { 
    //$record_num = $this->uri->segment($this->uri->total_segments()); 
    //$list = $this->cek_list->get_datatables($record_num);// not needed in demo 
    $this->table_generate = '555'; // populating the test data 

/*.....*/ 
} 

public function generate_pdf_laporan() { 
    echo "<pre>"; 
    print_r ($this->table_generate); //Empty 
} 
} 

$test = new Cek_list_wire_rod(); 
$test->ajax_list(); // calling this method since the value is being populated in this method. 
$test->generate_pdf_laporan(); 

此外，這只是使用class屬性來存儲數據而不使用全局變量。

由於代碼方便，您需要先調用ajax_list()方法，然後調用generate_pdf_laporan()方法，因爲該屬性及其值在前者中設置。
