Stir-fried cold rice. What should I do?

Stir-fried cold rice. The last time I saw someone using str_replace, it could be written as an array. For more information, see the link. $ trans = array (& quot; hello & quot; = & gt; & quot; hi & quot;, & quot; hi & quot; = & gt; stir-fried rice.

------ Solution --------------------
$ Trans = array ("hello" => "hi", "hi" => "hello ");
Echo strtr ("hi all, I said hello", $ trans );


Hello all, I said hi
