Compare

Measurements can also be compared, but without automatic unit conversion. Thus, equals() returns TRUE, only if both the value and the unit of measure are identical.

Example 617. Different measurements

<?php
// Define measurements
$unit = new Zend_Measure_Length(100Zend_Measure_Length::CENTIMETER);
$unit2 = new Zend_Measure_Length(1Zend_Measure_Length::METER);

if (
$unit->equals($unit2)) {
    print 
"Both measurements are identical";
} else {
    print 
"These are different measurements";
}


Example 618. Identical measurements

<?php
// Define measurements
$unit = new Zend_Measure_Length(100Zend_Measure_Length::CENTIMETER);
$unit2 = new Zend_Measure_Length(1Zend_Measure_Length::METER);

$unit2->setType(Zend_Measure_Length::CENTIMETER);

if (
$unit->equals($unit2)) {
    print 
"Both measurements are identical";
} else {
    print 
"These are different measurements";
}
