获取 PHP CodeIgniter 中回显字符串的值？

发布于 2024-12-20 04:22:34 字数 405 浏览 2 评论 0原文

我需要在 CodeIgniter 或 PHP 中获取回显字符串的值。

例如

class SampleClass {

 function myFunc() {
  echo "true"; 
 }

}

class TestSampleClass {

 $obj = new SampleClass();
 function test_myFunc() {
  $obj->myFunc();
  // I want to get the 'true' string to be compared..
  // how can i get the string 'true' that is echoed in myFunc()
 }

}

这可能吗？

请帮忙。

多谢。

虽然我认为这个问题与 CodeIgniter 无关，但您可以通过捕获缓冲区并将其发送到某个回调函数以明确检查输出来完成此

<?php
class SampleClass {

 function myFunc() 
 {
    echo 'true'; 
 }

}

class TestSampleClass {

 static function compare($buffer)
 {
    if ($buffer == 'true')
    {
       return 'Yes, it was true';
    }
    else
    {
       return 'Sorry, it was not true';
    }
 }

 function test_myFunc() 
 {
    $obj = new SampleClass();

    ob_start('TestSampleClass::compare');

    $obj->myFunc();

    ob_end_flush();
 }

}

$TSC = new TestSampleClass;

echo $TSC->test_myFunc();
?>

While i think this question has nothing to do with CodeIgniter, you could do it by capture the buffer, and send it into some callback function to explicitely inspect the output

<?php
class SampleClass {

 function myFunc() 
 {
    echo 'true'; 
 }

}

class TestSampleClass {

 static function compare($buffer)
 {
    if ($buffer == 'true')
    {
       return 'Yes, it was true';
    }
    else
    {
       return 'Sorry, it was not true';
    }
 }

 function test_myFunc() 
 {
    $obj = new SampleClass();

    ob_start('TestSampleClass::compare');

    $obj->myFunc();

    ob_end_flush();
 }

}

$TSC = new TestSampleClass;

echo $TSC->test_myFunc();
?>
