# jupitern/file-parser
#### PHP File Parser.
read, filter, parse and format {csv, tsv, dsv, variable-length-delimited} and other txt files
## Requirements
PHP 5.4 or higher.
## Installation
Include jupitern/file-parser in your project, by adding it to your composer.json file.
```javascript
{
"require": {
"jupitern/file-parser": "1.*"
}
}
```
## Usage
```php
Given a csv file "filename.csv" with contents (animal, category, count):
animal,type,count
crocodile,reptile,4
dolphin,mammal,0
duck,bird,2
koala,mammal,4
lion,mammal,5
lets parse the file with:
- ignore the first line
- convert encoding to ISO-9959-1
- convert lines to objects
- remove animals with count 0
- format the animal type to uppercase
- group by type
// read a file to array
$objectsArr = \Jupitern\Parser\FileParser::instance()
->setFile("csv.txt", ',')
->setEncoding('ISO-8859-1', 'UTF-8')
->toObject(['animal', 'type', 'animalCount'])
->filter(function ($line, $lineNumber) {
return $lineNumber > 1 && $line->animalCounnt > 0;
})
->format('type', function ($val) {
return strtoupper($val);
})
->group(function ($line) {
return $line->type;
})
->parse();
echo '
';
print_r($objectsArr);
/*
output:
Array
(
[REPTILE] => Array(
[0] => stdClass Object(
[animal] => crocodile
[type] => REPTILE
[number] => 4
)
)
[BIRD] => Array(
[0] => stdClass Object(
[animal] => duck
[type] => BIRD
[number] => 2
)
)
[MAMMAL] => Array (
[0] => stdClass Object(
[animal] => koala
[type] => MAMMAL
[number] => 4
)
[1] => stdClass Object(
[animal] => lion
[type] => MAMMAL
[number] => 5
)
)
[FISH] => Array
(
[0] => stdClass Object(
[animal] => áéíóú
[type] => FISH
[number] => 3
)
)
)
*/
For the same file lets parse with:
- convert encoding to ISO-9959-1
- convert lines to arrays
- remove animals with count 0
- group by type
$objectsArr = \Jupitern\Parser\FileParser::instance()
->setFile("csv.txt", ',')
->setEncoding('ISO-8859-1', 'UTF-8')
->filter(function ($line) {
return $line[2] > 0;
})
->group(function ($line) {
return $line[1];
})
->parse();
echo '
';
print_r($objectsArr);
/*
Output:
Array
(
[reptile] => Array
(
[0] => Array(
[0] => crocodile
[1] => reptile
[2] => 4
)
)
[bird] => Array(
[0] => Array(
[0] => duck
[1] => bird
[2] => 2
)
)
[mammal] => Array
(
[0] => Array(
[0] => koala
[1] => mammal
[2] => 4
)
[1] => Array(
[0] => lion
[1] => mammal
[2] => 5
)
)
[fish] => Array
(
[0] => Array(
[0] => áéíóú
[1] => fish
[2] => 3
)
)
)

Given a dsv file "file.txt" with contents (empolyee number, birth date, monthly income):
01john doe 1980-01-01 923.5
01luis west 1976-01-01 1143.3
01madalena 1983-01-01 2173.6
02Jaqueline Wayne 1983-01-01 822.44
05luís manuel 1983-01-01 1323.52
lets parse the file doing:
- convert encoding to ISO-9959-1
- convert lines to objects
- format person name capitalize first letters
- group by wage bellow or above 1000
$objectsArr = \Jupitern\Parser\FileParser::instance()
->setFile("test.txt")
->setEncoding('ISO-8859-1', 'UTF-8')
->each(function ($line){
$obj = [];
$obj['Number'] = mb_substr($line, 0, 2);
$obj['Name'] = mb_substr($line, 2, 16);
$obj['BirthDate'] = mb_substr($line, 18, 10);
$obj['MonthlyIncome'] = (float)mb_substr($line, 28, 15);
return (object)$obj;
})
->format('Name', function ($val) {
return ucwords($val);
})
->group(function ($line) {
return (float)$line->MonthlyIncome >= 1000 ? 'above 1000' : 'bellow 1000';
})
->parse();
echo '
';
print_r($objectsArr);
/*
Output:
