我在 codeigniter 工作，突然收到一个奇怪的错误。以下文件运行良好，但突然停止执行 php 代码。当我去检查错误日志时，这是它的错误。
[09-Jun-2014 14:36:58 America/Denver] PHP Fatal error: Call to undefined function phpob_start() in /*/views/mobile_views/templates/header.php on line 1
看起来它以某种方式组合了前两行。当我试图删除 ob_start() 语句时，它开始为下一行提供错误。
知道突然发生了什么吗？我已经复制并粘贴了整个文件代码如下。
谢谢。
<?php
ob_start();
$user_name = $this->session->userdata('interactin_username');
$name = '';
if (isset($user_name) && $user_name != '') {
$name = $user_name;
} else {
$name = 'Guest';
}
$header_link = "frontend_individual";
if ($this->session->userdata('interactin_user_type') == "3") {
$header_link = "frontend_business";
}
?>

最佳答案
尝试删除带有 <?php 的行完全(以确保任何特殊字符都消失)，然后在 ob_start(); 之前添加一个额外的换行符这样你就有了:
<?php
ob_start();
$user_name = $this->session->userdata('interactin_username');
$name = '';
关于php - 调用未定义函数 phpob_start()，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24128799/
