Pdf to text converter using php

Thanks a lot That class is very useful. In this I want just a url from pdf. Any way to find that? The class includes an output buffer flush that can cause 'headers already sent' errors.

Seemingly no ill-effects if you disable it for any reasonable size of document. Yes, class is not working for all. Do you have any other suggestion? You may want to try pdfparser.

You can even test how the library works in this page.

The only limitation of this parser is that it can't handle secured documents. The preferred way to install this library is via Composer. Open a new terminal, switch to the directory of your project and execute the following command on it:.

If you don't like to install new libraries directly with the terminal on your project, you can still modify the composer. Save the changes and then execute composer install in your terminal. Same as the SetCaptures method, but loads the capture definitions from a string instead of a file. The method returns an array of two values containing the page number and text offset if the searched string has been found, or false otherwise.

Searches for ALL occurrences of a given string in the pdf document. For example, if a pdf document contains the string "here" at character offset and in page 1, and position in page 3, the returned value will be :. As for their PHP counterparts, these methods return the number of matched occurrences, or false if the specified regular expression is invalid.

This section describes the properties that are available in a PdfTText object. Note that they should be considered as read-only. A string to be used for separating chunks of text. The main goal is for processing data displayed in tabular form, to ensure that column contents will not be catenated. However, this does not work in all cases. In this case, the default separator will be a white space. A string containing the document creation date, in UTC format. The value can be used as a parameter to the strtotime PHP function.

Some PDF documents may come with garbage at the beginning ; this is "illegal" of course, but Acrobat Reader is able to cope with that. So can do the PdfToText class The revision number of the Standard security handler that is required to interpret this dictionary. The revision number is :. Defined only when EncryptionAlgorithm is 2 or 3.

Length of key, in bits, used for encryption and decryption. The size is a multiple of 8, with a minimum value of 40 and maximum value of A flag coming from a password-protected file that says is the document metadata is also encrypted.

This property is expressed in percents ; it gives the extra percentage to add to the values computed by the PdfTexterFont::GetStringWidth method.

To determine whether two consecutive blocks of text on the same should be separated by a space, the class will empirically add this extra percentage to the computed string length. The default value is -5 percent. Name of the file whose text contents have been extracted. This value will be an empty string if the LoadFromString method has been called instead of Load.

A pair of unique ids generated for the document. The value of ID is used for decrypting password-protected documents. For example, the following template using the same example PDF file as above :. It can be any of the constants defined by the gd library regarding image formats :.

Note that the association between the constant and corresponding file suffix is automatically handled. An array of objects inheriting from the PdfImage class. Currently, only the PdfJpegIMage class is implemented.

Currently, images stored in proprietary Adobe format are not processed and will not appear in this array. Number of images found in the supplied PDF file. This number will only take into account the images whose format is recognized by the PdfToText class. This property is set to true if the Pdf file is encrypted through some kind of password protection scheme. Specifies a maximum execution time in seconds for processing a single file.

This allows the script to gracefully handle the error instead of PHP itself. Positive values are indicated in seconds. Maximum number of images to be extracted. This static property is the same as MaxExecutionTime , except that it works globally.

If you have to process x files, then it will ensure that the global execution time does not exceed the value of this property. Maximum number of pages to be selected. The default is the value 0, meaning that all pages will be selected for output.

A value of 1 will extract the contents of the first page only, which can be useful if your PDF file is large and you're only interested by the contents of the first page. When this number is negative, selection starts from the end of the file : -1 means "extract the last page", -2 means "extract the last two pages", and so on.

For certain ranges of values, when displayed on a graphical device, these consecutive characters appear to be separated by one space or more. Of course, when generating ascii output, we would like to have some equivalent of such spacing.

This is what the MinSpaceWidth property is meant for : insert an ascii space in the generated output whenever the offset found exceeds MinSpaceWidth text units. A string containing the last document modification date, in UTC format.

Note that the elements will not be mapped in the output exactly as they appear with Acrobat Reader : elements physically disjoint on the x-axis will be separated by a space by default. The BlockSeparator property can be used to modify this separator.

The following text for example :. Company1 Company2 address1 address2 city1 city2 will be rendered as :. For example, the following text :. Associative array containing individual page contents. The array key is the page number, starting from 1. String to be used when building the Text property to separate individual pages. The default value is a newline. A string to be used for separating blocks when a negative offset less than thousands of characters is specified between two sequences of characters specified as an array notation.

This trick is often used when a pdf file contains tabular data. A string containing the whole text extracted from the underlying pdf file. Note that pages are separated with a form feed. 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.

It can be a combination of any of the following flags :. Current version of the PdfToText class, as a string containing a major, minor and release version numbers. For example : "1. This exception is thrown if an error occurs when decoding a PDF object. Normally, most of these exceptions are thrown only if debug mode is activated.

Thrown when an error is detected while parsing a template file for retrieving form data, or when retrieving form data. 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. 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. It has been taken from a very common form used in the US, located here :. You can open 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 Using an XML template does not require many changes to your existing code ; you just need to supply the path of your XML template when calling the GetFormData method :.

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. String fields within a form are basically specified with the following XML field construct :.

They basically contain the same information as string fields, except that the type attribute is set to choice. Grouped fields allow you to create new properties, coming from the concatenation of existing fields.

A typical definition looks like this :. As a preliminary step, download the pdftohtml. Put your source PDF file in the same folder and follow the steps outlined below:. Note : In the PHP script shown above, "source.

The argument below, which is a component of the above script, defines a specific page range for conversion:. With cloud integration built-in, this is a truly cross-platform PDF editor for professionals as well as organizations of all sizes. Not only can you edit any existing component of a PDF without having to convert it into another file type, but you can also do the following tasks:.
