If you don't want to type the alphabet manually, you can do the folowing:
如果您不想手动输入字母，可以执行以下操作：
<?php
function getRandomWord($len = 10) {
$word = array_merge(range('a', 'z'), range('A', 'Z'));
shuffle($word);
return substr(implode($word), 0, $len);
}
If this is a database id, i suggest you the folowing:
如果这是一个数据库 ID，我建议您使用以下方法：
function createUniqueId() {
while (1) {
$word = getRandomWord();
if (!idExists($word)) { // idExists returns true if the id is already used
return $word;
}
}
}

function getrandomstring($length) {
global $template;
settype($template, "string");
$template = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
/* this line can include numbers or not */
settype($length, "integer");
settype($rndstring, "string");
settype($a, "integer");
settype($b, "integer");
for ($a = 0; $a <= $length; $a++) {
$b = rand(0, strlen($template) - 1);
$rndstring .= $template[$b];
}
return $rndstring;
}

<?php
$letters = array ( "a" ,"b" ,"c" ,"d" ,"e" ,"f" ,"g" ,"h" ,"i" ,"j" ,
"k" ,"l" ,"m" ,"n" ,"o" ,"p" ,"q" ,"r" ,"s" ,"t" ,
"u" ,"v" ,"w" ,"x" ,"y" ,"z" );
function letterfNum($letterNumber ,$resoltNumber){
global $letters;
for ($i = 0 ; $i < $resoltNumber ;$i++){
$lettersTotal = "";
$rand = array_rand($letters,$letterNumber);
foreach($rand as $key => $letterIndex){
foreach($letters as $orginalIndex => $orginalValue){
if ($letterIndex == $orginalIndex){
$lettersTotal .= $orginalValue;
}
}
}
echo $lettersTotal."<br>";
}
}
letterfNum(5,6);
?>

All you need is to use uniqid.
您只需要使用uniqid.
echo uniqid(null, true);
