An easy to use php library to show log on js console Debug php without broking your front
composer require guilhem/js-logJsLog is a minimalist library allowing you to put debug message along your code.
- Import the package in your code:
require('vendor/autoload.php');
use JsLog\JsLog;
// Generate an instance like this
$jslog = JsLog::getInstance();- Use it
// Use it from the instance
$jslog->log('Your log');
// Or use it without instance
JsLog::getInstance()->msg('Success message !');
// Render error
$jslog->err('Error triggered...');- Custom renderer
Jslog allow you to render your message with css via a custom function:
// Render a custom message, with customm CSS
$jslog->custom(
"[CUSTOM DEBUG]\n", "color:orange",
"Whouhou it worked\n", "color:red;border:1px solid red;",
"Whouhou it worked\n", "color:darkgrey;font-weight:800;",
"..Debug stop..\n", "color:blue;font-weight:bold"
);- See messages
Into your web browser watch the javascript console
- When debug messages are sent ?
If you pass the True args at the construction Jslog will send debug only when output buffering have started. Else, message will be put in a FIFO array. The queue of messages will be flushed at the next call of a log function or at the end of the script. Else, it will send debug message directly when called
Here is the results of the following script:
<?php
require('vendor/autoload.php');
use JsLog\JsLog;
// By adding True jsLog will wait until headers has been sent (relying on ob if activated else `headers_sent` function)
// By default, it is called with none, and will log as soon as called :D
JsLog::getInstance(True)->log('Hey from javascript console before headers was sent');
echo "<!DOCTYPE html><html><head></head><body>";
$jslog = JsLog::getInstance();
$jslog->msg("A message from PHP display in js console");
$jslog->err("Error here: \"" . $_SERVER['SCRIPT_NAME'] . '"');
$jslog->custom(
"[CUSTOM DEBUG]\n", "color:orange",
"Whouhou it worked\n", "color:red;border:1px solid red;",
"Whouhou it worked\n", "color:darkgrey;font-weight:800;",
"..Debug stop..\n", "color:blue;font-weight:bold"
);
echo "</body></html>";Inside the javascript console:
