but, if use in php script nothing happen. Can anybody provide explanation on what is the exact issue with

Answer 1

Well, I can see that you typed "-convert-to pdf" instead of "--convert-to-pdf". Maybe you did a similar typo in your php script? Hard to say without seeing the PHP code, though.

Please provide details: how do you call libreoffice from PHP, what do the error logs say etc.

Finally, if you are running SElinux and not Ubuntu, please take the question to a SELinux forum.

Answer 2

you are missing the filter name

This is the general format of convert-to (noting that on windows the parameter is :

-convert-to not --convert-to

soffice --headless --convert-to <TargetFileExtension>:<NameOfFilter> file_to_convert.xxx

Use the link to look for the filter names in the .xcu files.

For example, I wanted to convert to Excel 95 format so I found the MS_Excel_95.xcu filter and inside it has a name:

<node oor:name="MS Excel 95" oor:op="replace">
     ...

I could then try it out:

soffice --headless --convert-to xls:"MS Excel 95" filename.xlsx

(I needed this to get a non-xml version of an excel file)
