T_PUBLIC，期望T_STRING使用require()

当我通过require()链接到我的函数时，我得到了一个错误

错误:Parse error: syntax error, unexpected T_PUBLIC, expecting T_STRING in /home/content/23/9953123/html/new/lib/functions.php on line 3

<?php
require("lib/functions.php");
require("lib/dbconnect.php");
?>

:显然也

<?php
function stateToAbb($input){ 
//reset found 
$found = 0; 
//list states 
$states = "Alaska,Alabama,Arkansas,Arizona,California,Colorado,Connecticut,Delaware,Florida,Georgia,Hawaii,Iowa,Idaho,Illinois,Indiana,Kansas,Kentucky,Louisiana,Massachusetts,Maryland,Maine,Michigan,Minnesota,Missouri,Mississippi,Montana,North Carolina,North Dakota,Nebraska,New Hampshire,New Jersey,New Mexico,Nevada,New York,Ohio,Oklahoma,Oregon,Pennsylvania,Rhode Island,South Carolina,South Dakota,Tennessee,Texas,Utah,Virginia,Vermont,Washington,Wisconsin,West Virginia,Wyoming"; 
//list abbreviations 
$abb = "AK,AL,AR,AZ,CA,CO,CT,DE,FL,GA,HI,IA,ID,IL,IN,KS,KY,LA,MA,MD,ME,MI,MN,MO,MS,MT,NC,ND,NE,NH,NJ,NM,NV,NY,OH,OK,OR,PA,RI,SC,SD,TN,TX,UT,VA,VT,WA,WI,WV,WY"; 
//create arrays 
$states_array = explode(",", $states); 
$abb_array = explode(",", $abb); 
//run test 
for ($i = 0; $i < count($states_array); $i++){ 
    if (strtolower($input) == strtolower($states_array[$i])){ 
        $found = 1; 
        $output = $abb_array[$i]; 
        return $output; 
    } 
} 
if ($found != 1){ 
    $output = $input; 
    return $output; 
} 
return $output; 
} 
?>

但是当我只是把函数放在文件中而不需要单独的php文件时，它工作得很好…

任何想法?

更新……

既然每个人都认为我在试图快速使用不同的代码…这是一个更新的代码…

<?php
require("lib/functions.php");
require("lib/dbconnect.php");
function stateToAbb($input) { 
    //reset found 
    $found = 0; 
    //list states 
    $states = "Alaska,Alabama,Arkansas,Arizona,California,Colorado,Connecticut,Delaware,Florida,Georgia,Hawaii,Iowa,Idaho,Illinois,Indiana,Kansas,Kentucky,Louisiana,Massachusetts,Maryland,Maine,Michigan,Minnesota,Missouri,Mississippi,Montana,North Carolina,North Dakota,Nebraska,New Hampshire,New Jersey,New Mexico,Nevada,New York,Ohio,Oklahoma,Oregon,Pennsylvania,Rhode Island,South Carolina,South Dakota,Tennessee,Texas,Utah,Virginia,Vermont,Washington,Wisconsin,West Virginia,Wyoming"; 
//list abbreviations 
$abb = "AK,AL,AR,AZ,CA,CO,CT,DE,FL,GA,HI,IA,ID,IL,IN,KS,KY,LA,MA,MD,ME,MI,MN,MO,MS,MT,NC,ND,NE,NH,NJ,NM,NV,NY,OH,OK,OR,PA,RI,SC,SD,TN,TX,UT,VA,VT,WA,WI,WV,WY"; 
//create arrays 
$states_array = explode(",", $states); 
$abb_array = explode(",", $abb); 
//run test 
for ($i = 0; $i < count($states_array); $i++){ 
    if (strtolower($input) == strtolower($states_array[$i])){ 
        $found = 1; 
        $output = $abb_array[$i]; 
        return $output; 
    } 
} 
if ($found != 1){ 
    $output = $input; 
    return $output; 
} 
return $output; 
} 
?>

It does not work…当我删除require("lib/functions.php");它的工作，所以问题是与那行代码
