Does PHP support conjunction and disjunction natively?
<p>Javascript employs the conjunction and disjunction operators.</p>

<p><em>The left–operand is returned if it can be evaluated as: false, in the case of conjunction (a &amp;&amp; b), or true, in the case of disjunction (a || b); otherwise the right–operand is returned.</em></p>

<p>Do equivalent operators exist in PHP?</p>
