php中==和===之间是否有区别?当我在条件语句中使用它们时，两者似乎都对我有效.我对使用PHP编程非常陌生.请考虑一下并用简单的词回答.

Is there any difference between == and === in php? both seem to work fine for me when i use them in a conditional statement. I am very new to programming in PHP. Please consider this and answer in simple words.

推荐答案

• $a == $b
• $a == $b

等于true :如果$a等于 $b，键入杂耍后.

Equal true: if $a is equal to $b, after type juggling.

• $a === $b

完全相同:如果$a等于$b，并且它们是相同类型.

Identical true: if $a is equal to $b, and they are of the same type.
