PHP gmp_export() Function

PHP has a built-in function called GMP export() that turns a GMP number into a binary string.

Syntax

The given syntax shows the PHP GMP export function.

Parameters

As shown above syntax and explained below, the GMP gmp_export() function takes three parameters:

$numbers: This is a required parameter for the GMP gmp_export() function. It is the number that the function will export.
$num_size: This parameter tells how many bytes are in each piece of binary data. Most of the time, this parameter is used with the options parameter. This parameter's default value is 1.
$option_num: GMP MSW FIRST | GMP NATIVE INDIAN is what this parameter is set to by default.

Return Values

If the function works, it gives back a string. If it doesn't work, it gives back FALSE.

Examples

Example1: the given example shows gmp_export() function with basic value. The given parameter shows string values of the positive and negative numbers. The export function does not affect the positive and negative numbers.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_export () Function </h4>
<?php
echo "<p> Display numerical value into binary string </p>";
$value1 = gmp_export(16705);
$value2 = gmp_export(17001);
$value3 = gmp_export(18000);
echo "The export data of the GMP numbers (16705): ";
print_r($value1);
echo "<br/>";
echo "The export data of the GMP numbers (17001): ";
print_r($value2);
echo "<br/>";
echo "The export data of the GMP numbers (18000): ";
print_r($value3);
$value4 = gmp_export("-17001");
$value5 = gmp_export(-18000);
echo "<br/>";
echo "The export data of the GMP numbers (-17001): ";
print_r($value4);
echo "<br/>";
echo "The export data of the GMP numbers (-18000): ";
print_r($value5);
?>
</body>
</html>

Output:

The given output shows the gmp_export() function and its data.

Example2: the given example shows a value with the variable value.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_export () Function </h4>
<?php
echo "<p> Display numerical value into binary string </p>";
$num1 = "20000";
$num2 = "10101";
$num3 = "30218";
$num4 = "16709";
$value1 = gmp_export ($num1);
$value2 = gmp_export($num2);
$value3 = gmp_export ($num3);
$value4 = gmp_export ($num4);
echo "The export data of theGMP numbers: ";
print_r($value1);
echo "<br/>";
echo "The export data of the GMP numbers: ";
print_r($value2);
echo "<br/>";
echo "The export data of the GMP numbers: ";
print_r($value3);
echo "<br/>";
echo "The export data of the GMP numbers: ";
print_r($value4);
?>
</body>
</html>

Output:

The given output shows the gmp_export() function and its data.

Example3: the export function uses number count with a basic GMP parameter. We can see the difference between default word count and user word count.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_export () Function </h4>
<?php
echo "<p> Display numerical value into binary string </p>";
$num1 = "26709";
$num_count = "1";
$num_counts = "4";
$num4 = "16709";
$value1 = gmp_export ($num1,$num_count);
$value4 = gmp_export ($num4,$num_count);
echo "The export data of the GMP numbers: ";
print_r($value1);
echo "<br/>";
echo "The export data of the GMP numbers: ";
print_r($value4);
$value2 = gmp_export ($num1,$num_counts);
$value3 = gmp_export ($num4,$num_counts);
echo "<br/>";
echo "The export data of the GMP numbers: ";
print_r($value2);
echo "<br/>";
echo "The export data of the GMP numbers: ";
print_r($value3);
?>
</body>
</html>

Output:

The given output shows the gmp_export() function and its data.

Example4: the given example shows the export function with the other GMP function. Here, we use the complement and absolute data functions.

<!DOCTYPE html>
<html>
<body>
<h4> PHP gmp_divexact() Function </h4>
<?php
$num1 = "-26709";
$num2 = "-16709";
$num3 = gmp_com($num1);
$num4 = gmp_abs($num2);
$value1 = gmp_export ($num3);
$value4 = gmp_export ($num4);
echo "The export data of the GMP numbers: ";
print_r($value1);
echo "<br/>";
echo "The export data of the GMP numbers: ";
print_r($value4);
?>
</body>
</html>

Output:

The following output shows the gmp_export() function and its data.

Conclusion

The division "gmp_export ()" function uses the GMP parameter for mathematical operation. It gets the binary string value of the given function's parameter. The function removes lengthy conversion operations code using operators and values.
