TCPDF is an Open Source PHP class for generating PDF files on-the-fly without requiring external extensions. This class is already adopted by a large number. PDF_encoding_set_char — Add glyph name and/or Unicode value; PDF_end_document — Close PDF file; PDF_end_font — Terminate Type 3 font definition. Using the TCPDF library: php"); $pdf = new TCPDF (); // set document information $pdf->SetCreator(PDF_CREATOR);.

The SetaPDF-Stamper allows PHP developers to add new content to existing PDF documents in a fast, easy, and reliable way. Vulnerability patched last year, but many websites and web apps will most likely remain vulnerable for years. Pdfcrowd is a Web/HTML to PDF online service. Convert HTML to PDF online in the browser or in your PHP, Python, Ruby,.NET, Java apps via the REST API.
Text A string containing the whole text extracted from the underlying pdf file.
Note that pages are separated with a form feed. Title Document title, as specified in the author information object. Utf8Placeholder When a Unicode character cannot be correctly recognized, the Utf8Placeholder property will be used as a substitution.
The string can contain format specifiers recognized by the sprintf function.
The parameter passed to sprintf is the Unicode codepoint that could not be recognized an integer value. For example : "1. Normally, most of these exceptions are thrown only if debug mode is activated.
Form data extraction Extracting form data is fairly simple : use the GetFormData method and it will return you an object containing all the field values contained in your PDF file, whether they have been filled or not.
You have two ways to retrieve form data : Either by supplying an XML template, that maps actual form field names to more readable names. It provides additional features such as the ability of grouping field values together Or by relying on the default behavior, which will return the form field names as they are defined in the PDF file.
Both methods return a new object inheriting from the PdfToTextFormData class, which mainly contain helper functions that have no interest for the caller. The derived class returned by the GetFormData method has a set of properties that give you access to the form fields contents. The examples given in the following sections are based on the file "sample.
This is why you may want to spend some time designing a template XML file that maps PDF field names to human-readable ones All of the above have been defined in the template file, and the parent class, PdfToTextFormData, is able to handle any modifications made to any of the properties involved in a grouped property. Now, this is time to have a look at what is a template. This is described in the next section.
Please note that the above information could be subject to changes in future releases. Defining fields Form fields can currently be of three types : String fields Choice fields. This is typically used for radiobutton-like checkboxes, which represent a unique field that can have different value, depending on what is checked.
Choice fields allow you to associate constants to each individual value. Grouped fields. Grouped fields are virtual fields that are the result of the concatenation of several existing fields. Fill the values. Grouped fields Grouped fields allow you to create new properties, coming from the concatenation of existing fields.
The above example creates an SSN property, which is the result of the concatenation of the specified fields. The required attributes are the following : name : Name of the grouped property fields : A comma-separated list of existing field names that should be grouped together separator : Separator string used to separate each component of the grouped field.
Note that modifying the value of a property referenced by a grouped field will modify the corresponding grouped field value. Similarly, modifying the grouped field value will modify its associated properties.
Capturing text Sometimes, it's easier to tell the PdfToText class which area s of text you want to retrieve from which page s , rather than having to struggle with regular expressions to isolate the information you want. This is especially true when you want to retrieve data from tabular reports. Captures are a solution for such needs ; they allow you to define shapes of the following types : Rectangles : rectangles are used to surround areas of text whose contents you want to extract after processing.
Lines : allow you to capture lines and columns within lines when you have to process a report presented in tabular format. Areas to be captured are specified using a capture definition file or string, in XML format. A step-by-step overview Capturing areas of your PDF document will require you a few preliminary steps that involve some extra work.
Determining what to capture A PDF file uses a coordinate system whose values are more or less expressed in "relative units".
The point at coordinates 0,0 is located at the bottom-left corner of the page ; the point at coordinates x,y , where "x" is the page width and "y" the page height, is located at the top-right corner of the page. That's nice, but how to find the coordinates x, y, width and height of the rectangle that contains the text you want to capture?
But if you don't have such a tool, you're stuck. This may be the only occasion you will have to use this option. The following example script explains how the file sample-report. It gives the page number, its width and its height in graphics coordinates. The second kind of information that appears between square brackets gives size information regarding the block of text immediately following it : [x An example is given below, which will capture some contents of the PDF file sample-report.
Line heights are 16 in both cases. Inside this group of lines, you can specify as many columns you want to capture in our example, only one column is defined ; its name is "Column1". All the coordinates, widths and heights listed in this definition have been taken from the information contained in file sample-report.
Each tag that has been defined in the XML definition file sample-report. There will be a capture for each page of the document, even if not present in the list of applicable pages.
