How get a full Realtime Logs from vercel of php laravel?

[guoxiangke]

Hello, I deploy a laravel to vercel, the homepage works well.
But after I config cache drive, there are something wrong, I want debug. while the logs show like this.
which transcated, no No1 line.

• Version: vercel-php@0.5.2
• URL: No

BTW, the laravel works well with predis cache from upstash on my local.
Also the LOG_LEVEL and debug set true, but always show 500.

Hi, realtime logs in Vercel dashboards are collected form STDOUT or STDERR, just write to stdout/stderr.

Tip

PHP GPT

In PHP, you can write to both standard output (stdout) and standard error (stderr) using fwrite(). Here's how you can do that:

Writing to stdout (Standard Output)

Standard output is the default for echo or print, but if you want to explicitly write to stdout, you can use:

<?php
// Writing to stdout using fwrite
fwrite(STDOUT, "This is standard output.\n");

// Alternatively, you can use echo or print, which also writes to stdout
echo "This is also standard output.\n";
?>

Writing to stderr (Standard Error)

To write to the standard error stream, you need to use fwrite() with STDERR:

<?php
// Writing to stderr using fwrite
fwrite(STDERR, "This is an error message written to stderr.\n");
?>

Both examples will output messages, but the one to stderr will be directed to the error stream, useful for logging errors separately from normal output.
