if if pdf文件存在codeigniter

Question

我想从我的目录中打开pdf文件。如果文件存在，它将从我的目录打开它，它的工作原理。但是，如果pdf文件不存在，我希望它返回测试，就像在我的代码中，它仍然无法正常工作。请帮我。谢谢

代码视图如下：

<?php
if ($this->pos != 1) {
    if (!$id) {
        ?>
        <tr>
            <td colspan="2" >
                <label><input type="checkbox" name="use_form" value="1"/>make a quotation form after save this transaction</label>
            </td>
        </tr>
    <?php } else { ?>
        <?php if (!$quotation) { ?>
            <tr>
                <td colspan="5">
                    <a href="javascript:show_popUp('<?php echo base_url(); ?>index.php/service_tracking/trans_service/quotation/<?php echo $id; ?>')"> Create Quotation</a>
                </td>
            </tr>
        <?php } else { ?>
        <?php  $file = base_url()."quotation/".$quotation.".pdf";   ?>
        <?php if(file_exists($file)) {

                $file = $file;
            } 
            else {
                $file = "test";
                } ?>
            <tr>
                <td colspan="2">
                    <a target="_blank" href="<?php echo base_url(); ?>quotation/<?php echo $quotation;?>.pdf">View Quotation </a>
                </td>
                <td colspan="3">
                    <a href="javascript:show_popUp('<?php echo base_url(); ?>index.php/service_tracking/trans_service/edit_quotation/<?php echo $id; ?>')"> Revised Quotation</a>

所以你的问题确实是＆＃34;我如何检测文件是否存在？＆＃34;

在PHP中有一个内置函数，名为file_exists（）

echo|set /p="foo" | minigzip > text.txt

所以你需要将它合并到你的代码中。
