Spatie has introduced a package called Pdf-to-text that can be utilized to extract some text from a pdf. There are already some packages that can be used for this purpose, But Pdf-to-text package is really easy to use so you can easily utilize this package in your application. Under the hood, Spatie used a utility called pdftotext in this package.
Behind the scenes, this package leverages pdftotext. You can verify if the binary is installed on your system by issuing this command:
If it is installed it will return the path to the binary.
To install the binary you can use this command on Ubuntu or Debian:
apt-get install poppler-utils
On a mac you can install the binary using brew
brew install poppler
If you're on RedHat or CentOS use this:
yum install poppler-utils
You can install the package via composer:
composer require spatie/pdf-to-text
Extracting text from a pdf is easy.
$text = (new Pdf()) ->setPdf('book.pdf') ->text();
By default, the package will assume that the
pdftotext command is located at
/usr/bin/pdftotext. If it is located elsewhere pass its binary path to constructor
$text = (new Pdf('/custom/path/to/pdftotext')) ->setPdf('book.pdf') ->text();
or as the second parameter to the getText static method:
echo Pdf::getText('book.pdf', '/custom/path/to/pdftotext');
Sometimes you may want to use pdftotext options. To do so you can set them up using the setOptions method.
$text = (new Pdf()) ->setPdf('table.pdf') ->setOptions(['layout', 'r 96']) ->text();
or as the third parameter to the getText static method:
echo Pdf::getText('book.pdf', null, ['layout', 'opw myP1$$Word']);
Please note that successive calls to
setOptions() will overwrite options passed in during previous calls.
If you need to make multiple calls to add options (for example if you need to pass in default options when creating the Pdf object from a container, and then add context-specific options elsewhere), you can use the
$text = (new Pdf()) ->setPdf('table.pdf') ->setOptions(['layout', 'r 96']) ->addOptions(['f 1']) ->text();
If you want to know more about this package you can visit its documentation and source code on Github.
