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 600. Different measurements
<?php
// Define measurements
$unit = new Zend_Measure_Length(100, Zend_Measure_Length::CENTIMETER);
$unit2 = new Zend_Measure_Length(1, Zend_Measure_Length::METER);
if ($unit->equals($unit2)) {
print "Both measurements are identical";
} else {
print "These are different measurements";
}
Example 601. Identical measurements
<?php
// Define measurements
$unit = new Zend_Measure_Length(100, Zend_Measure_Length::CENTIMETER);
$unit2 = new Zend_Measure_Length(1, Zend_Measure_Length::METER);
$unit2->setType(Zend_Measure_Length::CENTIMETER);
if ($unit->equals($unit2)) {
print "Both measurements are identical";
} else {
print "These are different measurements";
}
