Tabs and Indents

Item	Description
Use tab character	If this check box is selected, tab characters are used: Otherwise, spaces are used instead of tabs.
Smart tabs	If this check box is selected, PhpStorm inserts tabs for indentation and reformatting, but fine alignment to a necessary column is done only via spaces. This is done in order to preserve visual representation of the source code, when the Tab Size is changed. If this check box is not selected, then spaces are used for alignment if necessary. This check box is available if the Use Tab Character check box is selected.
Tab size	In this text box, specify the number of spaces included in a tab.
Indent	In this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted for each indent level.
Continuation indent	In this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted at the next line in case of a construct break.
