အကယ်. အစ နှင့် အရှည် အရအခမ်းအနားများသည် string အရှည်ထက်ကျော်လွန်ပါက function ကိုထုတ်ပေးသည် -

 <span class="token php language-php"><span class="token delimiter important"><? PHP</span>
<span class="token keyword">ECHO</span> <span class="token variable">$ str</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"ဒီဟာကောင်းတယ်</span> <span class="token punctuation">"</span>
