# PHP: Introduction Operator

Table of arithmetic operators

Sample Script aritmatika.php

\$ value1 = 32;
\$ value2 = 8;
\$ number = \$ value1 + \$ value2;
\$ less = \$ nilai1- \$ value2;
\$ time = \$ value1 * \$ value2;
\$ to = \$ value1 / \$ value2;
\$ remainder = \$ value1% \$ value2;
print "Reviews Arithmetic operation Example";
print "The value \$ value1 = \$ value1 and \$ value2 = \$ nilai2
";

print " \$ value1 + \$ value2 = \$ amount most";
print " \$ value1 - \$ value2 = \$ less than most";
print " \$ value1 * \$ value2 = \$ times the most";
print " \$ value1 / \$ value2 = \$ for most";
print " \$ value1% \$ value2 = \$ leftovers most";
?>

### Know the assigment operator

The following table of symbols and Functions of the assignment operator used

Example Scripts assignment.php

\$data1=10;
\$data1+=2;

";
\$data2=10;
\$data2-=5;

";
\$data3=10;
\$data3*=4;

";
\$data4=20;
\$data4/=5;

";
\$data5=12;
\$data5%=7;

?>

### Know Comparison Operators

Table of comparison operators such as below

Example Scripts perbandingan.php

\$a=12;
\$b=13;

print "Variabel \$a = \$a dan \$b = \$b

";

print("Nilai \$a == \$b adalah %s
",\$a==\$b);
print("Nilai \$a <> \$b adalah %d
",\$a<>\$b);
print("Nilai \$a > \$b adalah %d
",\$a>\$b);
print("Nilai \$a < \$b adalah %d
",\$a<\$b);
print("Nilai \$a <= \$b adalah %d
",\$a<=\$b);
print("Nilai \$a >= \$b adalah %d

",\$a>=\$b);

print"Keterangan:
";
print "Nilai 1 berarti Benar/True
";
print "Nilai 0 berarti Salah/False";

?>

There are other operators are included in the category of comparison operators are ternary operator " ?". The use of the ternary operator is identical to the user if .. else . Pnggunaan example of the ternary operator is as follows:

Example Scripts ternary.php

The result:

### Know the String Operator

There are two types of operators used string operators . (Dot) operator . = (Colon equals) operator concatenate the arguments sent word to say that the right in an argument. While the operator . =Concatenate the arguments with a right hand to the left. The second function is similar operator to concatenate the words before and after. But the use of the operator. = More practical and operational results can be saved to the same variable. For more details, you can try the following script program. script String.php

\$a="Selamat ";
\$b=\$a."Datang";
print "\$b
";
\$a="Selamat"; \$b.="";print "\$b
";
?>

The result:
