    <p>I am trying to Fill in a PDF from PHP script. I am following the article by <strong>Sid Steward</strong> at the following <a href="http://www.mactech.com/articles/mactech/Vol.20/20.11/FillOnlinePDFFormsUsingHTML/index.html" rel="nofollow noreferrer">URL</a>.</p> <p>I have configured <strong>PDFTk</strong> package on <strong>CentOS</strong> linux distribution and I am able to execute the pdftk from the command prompt and it merges the FDF form with the PDF and successfully generates the flattened(Filled) PDF. I am using following command to test the Pdftk using shell.</p> <pre><code>pdftk /tmp/form.pdf fill_form /tmp/fdfbm0pe7 output /tmp/filledform.pdf flatten </code></pre> <p>But When try to execute a similar command through PHP, I am getting the error. The <strong>passthru</strong> command is failing with error code <strong>11</strong>. Following is the php code I am using to execute the command:</p> <pre><code>$command = 'pdftk form.pdf fill_form '. $fdf_fn. ' output - flatten'; passthru($command, $error); </code></pre> <p>The <strong>$fdf_fn</strong> above has the FDF file name. The <strong>form.pdf</strong> is the fill-able pdf form. Both the <strong>form.pdf</strong> and the PHP script file from which I have given the above lines of code are in the same folder. I have checked that PDFtk is executing correctly through PHP by echoing <strong>shell_exec('pdftk')</strong> and it was returning the standard help details.</p> <p>Just to provide more details, the path to pdftk is <strong>/usr/bin/</strong> and PHP script and PDF form files are located under <strong>/var/www/html/pdfmerge</strong>.</p> <p>Can some one please guide what I am doing wrong that the command execution through PHP is failing with error code 11?</p>

    1. COmight be a silly question , but can you just use shell_exec?

    2. CO@Brandon: I tried executing the shell_exec, it was returning NULL and no file was created in the result of command execution.
