PHP - Convert PDF to Text (No access to exec/shell_exec)

Question

The case:

• Server doesn't support exec/shell_exec (so pdftotext is excluded)
• Other libraries don't accept the PDF. Pdftotext works (tested on the files locally)

Here are some excerpts from the (PDF)code:

5 0 obj
>
stream
Gat$ugPXc?%"6H'p]ofd'_qs00UX27?3p0*8m>KOQL4]:u"*$$^'f*q*SGMee*e$5&=alj\@GV7YPq9pg!Lr0>Y2n'&lmd4Br?V9N

endobj

I would like to get some suggestions about how to convert this to plain text in PHP, without using the exec/shell_exec functions.

Thank you.

(Other solutions like http://webcheatsheet.com/php/reading_clean_text_from_pdf.php didn't work, and I couldn't get them to at least convert this code to something looking like ASCII-code.)

You cannot just parse this stream as you need to then decode the data using lots of other data in the file (like font encoding). You really want to use a library to do this...
