好的,我对我的日志记录类有另一个问题,但我希望能够将调用脚本的行号添加到日志文件条目中。
我见过__Line __ 但这给了我所在行的行号。
例子:
一个.php
$log = new Logger();
$log->debug('hello'); // Say this is line #20
现在,在 debug() 的 Logger.php 类中,我使用了__Line __ 魔术常量,例如第 300 行。当我运行脚本时,我希望日志条目显示为“第 20 行”,但它显示为“第 300 行”。除了将行号传递给函数之外,还有其他方法可以做到这一点吗?
示例调试类函数
public function debug($message) {
if(DEBUG) {
$this->calling_script = $this->getScriptBaseName();
$this->log_file = LOG_FILE_DIRECTORY."/".$this->calling_script.".log";
$this->fh = fopen($this->log_file, 'a') or die("Can't open log file: ".$this->log_file);
if($this->first_run) {
$this->log_entry = "\n[" . date("Y-m-d H:i:s", mktime()) . "][debug][line:".__LINE__."]:\t".$message."\n";
} else {
$this->log_entry = "[" . date("Y-m-d H:i:s", mktime()) . "][debug][line:".__LINE__."]:\t".$message."\n";
}
fwrite($this->fh, $this->log_entry);
fclose($this->fh);
$this->first_run = false;
}
}
编辑:debug_backtrace() 很好用!!!在下面工作
public function debug($message) {
if(DEBUG) {
$debug_arr = debug_backtrace();
$this->calling_script = $this->getScriptBaseName();
$this->log_file = LOG_FILE_DIRECTORY."/".$this->calling_script.".log";
$this->fh = fopen($this->log_file, 'a') or die("Can't open log file: ".$this->log_file);
if($this->first_run) {
$this->log_entry = "\n[" . date("Y-m-d H:i:s", mktime()) . "][debug]:\t".$message." [line:".$debug_arr[0]['line']."]\n";
} else {
$this->log_entry = "[" . date("Y-m-d H:i:s", mktime()) . "][debug]:\t".$message." [line:".$debug_arr[0]['line']."]\n";
}
fwrite($this->fh, $this->log_entry);
fclose($this->fh);
$this->first_run = false;
}
}
