I am using exec "wrapper" for linux commands in PHP: 

exec("unzip -oj tmp.zip -d tmp && rm tmp.zip");

Please tell me how can i convert spaces to underscores in filenames? Tnx,

  • You can do it all simply with PHP. [Extract the files](http://stackoverflow.com/a/8889126/315306) and then rename those who contain a space in the name – Raffaele Nov 27 '12 at 13:15

If you don'y mind using external utilities (as you're currently doing), you can use rename eg.

unzip -oj tmp.zip -d tmp && rename 's/\s/_/g' tmp/* && rm tmp.zip
