&gt;&gt;Is there a way to say &quot;Just give me the first n characters of a string&quot; 
&gt;&gt;in PHP?  For example, if the string was &quot;johndoe&quot;, and I just wanted the 
&gt;&gt;first 3 characters, or &quot;joh&quot;?  I think I could do it with some kind of 
&gt;&gt;regex, but I can't seem to come up with one that works.  It will be used 
&gt;&gt;in a MySQL query when it's done, like the following:
&gt;&gt;
&gt;&gt;$string = &quot;johndoe&quot;;
&gt;&gt;$newstring = justgivemetheleft3($string);
&gt;&gt;
&gt;&gt;$query = &quot;SELECT * from table where name like &quot;$newstring%&quot;
&gt;&gt;
&gt;&gt;I can't say give me everything that matches johndoe, because some of 
&gt;&gt;them are john doe, some are john_doe, some are john, etc.  But, the 
&gt;&gt;first 3 will always be right.
