脚本宝典收集整理的这篇文章主要介绍了php – 为什么这两个对象是相等的(==)？，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
($o1 == $o2) == TRUE.
为什么？
$o1的转储：
guITArchord Object ( [_guitarChord:guitarChord:PRivate] => [_chord:guitarChord:private] => chord Object() [_baseFret:guitarChord:private] => 0 [_frets:guitarChord:private] => Array ( [0] => x [1] => 0 [2] => 2 [3] => 2 [4] => 2 [5] => x ) [_tuning:guitarChord:private] => tuning Object() [currVARiation] => 0 [nextVariation] => [prevVariation] => )
$o2的转储：
guitarChord Object
(
[_guitarChord:guitarChord:private] =>
[_chord:guitarChord:private] => chord Object()
[_baseFret:guitarChord:private] => 0
[_frets:guitarChord:private] => Array
(
[0] => x
[1] => 0
[2] => 2
[3] => 2
[4] => 2
[5] => 0
)
[_tuning:guitarChord:private] => tuning Object()
[currVariation] => 0
[nextVariation] =>
[prevVariation] =>
)
编辑：
所以原因是因为(“x”== 0)= TRUE.谁能告诉我为什么？
