Download the PHP package intellex/debugger without Composer

Debugger for PHP

Simple and lightweight:

• Variable dump
• Incident rendering

Both of these features are divided and can used separately one from another.

Variable dumping

A single function to print out any variable type in an developer-friendly way.

Features

• Includes the file and line of calling.
• Automatically outputs in HTML, JSON or plain text, based on the environment.
• Very visible HTML output.
• Configurable.

Examples

Direct calling of the method.

// Will automatically show HTML, JSON or plain text format
VarDump::from($var);

Creating a quick debug function.

// The second parameter tells the debugger not to state this function as the dump file/line
function d($var) {
    VarDump::from($var, 1);
}

...

// Use it globaly
d('something');

Incident rendering

Will consider convert all errors to exceptions and render a page for any and every non handled exception.

Features

• Shows the exception and the stack trace with code snippets.
• Automatically outputs in HTML, JSON or plain text, based on the environment.
• Very visible HTML output.
• Configurable.

Examples

Simply register the IncidentHandler.

IncidentHandler::register();

Configuration

Both parts share the same configuration that is statically set. There are options that are used by only one part.

Default: 8

# Setter

# Getter

Max dump size

Default: 2097152

# Setter
\Intellex\Debugger\Config::setMaxDumpSize(:int)

# Getter
\Intellex\Debugger\Config::getMaxDumpSize(): int

Width for plain

The plain format is width of the box in the plain text format.

Default: 140

# Setter
\Intellex\Debugger\Config::setWidthForPlain(:int)

# Getter
\Intellex\Debugger\Config::getWidthForPlain(): int

Template

Force the template to use.

Default: auto detect from the environment

Possible values: 'html', 'json' or 'plain'

# Setter
\Intellex\Debugger\Config::setWidthForPlain(:string)

# Getter
\Intellex\Debugger\Config::getWidthForPlain(): string 

TODO

1. Tests for incident rendering.
2. Define the error types to ignore (ie. deprecated and strict).
3. Leverage JavaScript to show the HTML debug in a more practical way.
4. Plain text box to better handle multiline strings.
5. Be able to configure the color scheme for the outputs.
6. Create more stylish exception page.
7. Support for logging.
