如何捕获PHP致命错误("E_ERROR")? [英] How do I catch a PHP fatal (`E_ERROR`) error?
本文介绍了如何捕获PHP致命错误("E_ERROR")?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我可以使用set_error_handler()
捕获大多数PHP错误,但是对于致命的(E_ERROR
)错误(例如调用不存在的函数)无效.还有其他方法可以捕获这些错误吗?
I can use set_error_handler()
to catch most PHP errors, but it doesn't work for fatal (E_ERROR
) errors, such as calling a function that doesn't exist. Is there another way to catch these errors?
我正在尝试为所有错误呼叫mail()
,并且正在运行PHP 5.2.3.
I am trying to call mail()
for all errors and am running PHP 5.2.3.
推荐答案
使用register_shutdown_function
记录致命错误,需要PHP 5.2 +:
Log fatal errors using the register_shutdown_function
, which requires PHP 5.2+:
register_shutdown_function( "fatal_handler" );
function fatal_handler() {
$errfile = "unknown file";
$errstr = "shutdown";
$errno = E_CORE_ERROR;
$errline = 0;
$error = error_get_last();
if($error !== NULL) {
$errno = $error["type"];
$errfile = $error["file"];
$errline = $error["line"];
$errstr = $error["message"];
error_mail(format_error( $errno, $errstr, $errfile, $errline));
}
}
您将必须定义error_mail
和format_error
函数.例如:
You will have to define the error_mail
and format_error
functions. For example:
function format_error( $errno, $errstr, $errfile, $errline ) {
$trace = print_r( debug_backtrace( false ), true );
$content = "
<table>
<thead><th>Item</th><th>Description</th></thead>
<tbody>
<tr>
<th>Error</th>
<td><pre>$errstr</pre></td>
</tr>
<tr>
<th>Errno</th>
<td><pre>$errno</pre></td>
</tr>
<tr>
<th>File</th>
<td>$errfile</td>
</tr>
<tr>
<th>Line</th>
<td>$errline</td>
</tr>
<tr>
<th>Trace</th>
<td><pre>$trace</pre></td>
</tr>
</tbody>
</table>";
return $content;
}
使用 Swift Mailer 编写error_mail
函数.
