README
A variables dumper to help with debugging , designed to be a better alternative to the standard var_dump function in PHP.
Features
- Easy to use , zero configurations
- Dumps all types of data in PHP , including (int, float , strings , bool, objects, arrays, resources, enums, closures and anonymous classes)
- Auto recognition for text with known patterns like Emails , URLs .. etc
- Support dumping to CLI , Web content and files
- Pretty colorful output for CLI
- Interactive web debugging with folding for objects / arrays / long text
- Support dumping to
.jsonfiles - Could be used for logs , using the dump to file option
Installation
composer require agashe/var-dumper
Documentation
To start using Var-Dumper , all what you have to do , is to include the autoload.php file into your php script , then call one of the helpers functions.
<?php
require 'vendor/autoload.php';
d("data 1", "data 2");
The output of the prev example will be :
[ Time : 11-01-2024 07:43:24 / File : index.php / Line : 5 ]
string (11) => "hello world"
integer => 123
For each dump call , the dumper will automatically add the time , file name and the line number , so it became easier to debug in large projects , and log files.
Var-Dumper provides 4 helper functions that could be used anywhere in your project :
d(...$vars) and dump(...$vars) Functions
Those 2 functions are identical , they both can accept any numbers of variables and will serve the output based on your output type , either it's a CLI or Web.
d(null , 10.59, true);
dump(null , 10.59, true);
And here is the output :
[ Time : 11-01-2024 07:59:56 / File : test2.php / Line : 5 ]
NULL
double => 10.59
boolean => true
[ Time : 11-01-2024 07:59:56 / File : test2.php / Line : 7 ]
NULL
double => 10.59
boolean => true
The naming is just for sake of compatibility , like in case you wanted to replace old dumper , that use , d or dump as their function name.
dd(...$vars) Function
The dd function which stands for "dump and die" , unlike the 2 prev functions , this function will terminate the execution once the dump is complete.
In case you dump for web (in browser) , the dumper will return "500 Server Error" HTTP status code.
dump_tp_file($filePath, ...$vars) Function
Dump to file accept one mandatory argument before you path you variables for the dump. And the argument is the full path to the dump file.
class Foo {
public $name;
private $age;
}
$foo = new Foo();
$foo->name = "hello world";
dump_to_file(__DIR__ . '/path/to/dump.txt' , $foo);
Now let's check dump.txt , we should have something like :
[ Time : 11-01-2024 08:12:46 / File : index.php / Line : 12 ]
object (Foo) #2 (2) => {
name => "hello world"
age (private) => NULL
}
So far the dumper supports dumping to regular .txt and .json files. In case of a .json file , the dumper will automatically detect that from the extension.
In case of .txt files , the nes dump will be appended to the original content. First it will decode the old content , append the new json formatted content , then re-encode everything and save.
So assume we have a .json file called data.json with following content :
{
"some_data": {
"item_1": "data_1",
"item_2": "data_2",
"item_3": "data_3"
}
}
So now let's our prev example , but this time with that json file :
// ...
dump_to_file(__DIR__ . '/path/to/data.json' , $foo);
Now if we opened data.json , we will find that the content was appended :
{
"some_data": {
"item_1": "data_1",
"item_2": "data_2",
"item_3": "data_3"
},
"dump_e2bab7e": {
"timestamp": {
"time": "11-01-2024 08:23:55",
"file": "index.php",
"line": 13
},
"data": {
"object (Foo) #2 (2)": {
"name": "hello world",
"age (private)": "NULL"
}
}
}
}
The dump_e2bab7e is just and autogenerated unique hash identifier to prevent collision between dumps.
Examples
In the following examples we will see , different kind of use cases for the dumper and how the output will look like in each of the CLI / WEB / FILE / JSON outputs.
Basic data types
d('ahmed', 5.6, false, M_PI, NULL);
dump_to_file(__DIR__ . 'data.txt', 'ahmed', 5.6, false, M_PI, NULL);
dump_to_file(__DIR__ . 'data.json', 'ahmed', 5.6, false, M_PI, NULL);
Output CLI / TXT FILE :
[ Time : 11-01-2024 09:51:28 / File : index.php / Line : 5 ]
string (5) => "ahmed"
double => 5.6
boolean => false
double => 3.1415926535898
NULL
Output JSON :
{

"timestamp": {
"time": "11-01-2024 09:51:28",

"double": 3.1415926535898,

}
}
}
Output WEB :
