General Syntactic Characteristics<br />
• All variable names begin with $<br />
• The name part is like <strong>the</strong> names of variables in many<br />
programming languages: a letter or an underscore<br />
followed by any number of letters, digits, or underscores<br />
• PHP variables are case sensitive, but reserved words<br />
and function names are not. (Table 12.1)<br />
(Ex) while, WHILE, While, and wHiLe are same<br />
• Comments - three different kinds (Java and Perl)<br />
(a) // ... ; for single line<br />
(b) # ... ; for single line<br />
(c) /* ... */ ; for multiple-line<br />
