<?php

mb_internal_encoding('UTF-8');
echo mb_internal_encoding();
function convert($a) str_replace('â','a',$string);
$e=$_POST['aaa'];

<form method="post" action="#">
<textarea id="aaa" name="bbb" placeholder="send"  ></textarea>

**mb_internal_encoding(); output: "UTF-8"

textarea input: "âb" || php-output:âb script not convert "â"=>"a"

file is without BOM**

these may be other reasons?? what else can I try?

some typos there : 

function convert($a) str_replice('â','a',$string);

should be :

function convert($a){return str_replace('â','a',$a);}

not replice(),$string should be $a , also if you want to see the output from the function you should return it.

so when you call:

<?php echo convert("â");?>

it would output just fine

str_replice('â','a',$string);

应该：

 str_replace('â','a',$string);
