# PHP: Introduction Operator

Table of arithmetic operators
Sample Script aritmatika.php
<? 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 <br>”;
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”;
?>
The result:

### Know the assigment operator

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

Example Scripts assignment.php

<?php
\$data1=10;
\$data1+=2;

print “Nilai \\$data1 adalah \$data1 <br><br>”;
\$data2=10;
\$data2-=5;

print “Nilai \\$data2 adalah \$data2 <br><br>”;
\$data3=10;
\$data3*=4;

print “Nilai \\$data3 adalah \$data3 <br><br>”;
\$data4=20;
\$data4/=5;

print “Nilai \\$data4 adalah \$data4 <br><br>”;
\$data5=12;
\$data5%=7;

?>

The result:

### Know Comparison Operators

Table of comparison operators such as below

Example Scripts perbandingan.php
<?php
\$a=12;
\$b=13;

print “Variabel \\$a = \$a dan \\$b = \$b <br><br>”;

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

print”Keterangan:<br>”;
print “Nilai 1 berarti Benar/True<br>”;
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, 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

<?php
\$a=”Selamat “;
\$b=\$a.”Datang”;
print “\$b <br>”;
\$a=”Selamat”; \$b.=””;print “\$b<br>”;
?>The result:
