重点是，在运行我的脚本时，我插入了两次相同的用户。 当你＆＃34;回声＆＃34;在查询函数中不重复，很奇怪因为在phpmyadmin中没有发生，只能用我的脚本。
我留下我的代码：
function ar($a, $d = true){ // function test only
if($d){
echo '<pre>';
var_dump($a);
echo '</pre>';
}else{
echo '<pre>';
print_r($a);
echo '</pre>';
}
}
function SecureData($data){//cleaning up the data that will be inserted
global $conn;
if(is_array($data)){
foreach($data as $key=>$val){
if(!is_array($data[$key])){
$data[$key] = mysqli_real_escape_string($conn, $data[$key]);
}else{
$data[$key] = SecureData($data[$key]);
}
}
}else{
$data = mysqli_real_escape_string($conn, $data);
}
return $data;
}
//---->
function comillas($data, $s = "'"){// Wrap the string with a character
if(is_array($data)){
foreach($data as $key=>$val){
if(!is_array($data[$key])){
$data[$key] = $s.$data[$key].$s;
}else{
$data[$key] = comillas($data[$key]);
}
}
}else{
$data = $s.$data.$s;
}
return $data;
}
//---->
function error_mysql($conn = ''){// Evalua y returna un error en la consulta si la hay

}
return false;
}
//---->
function updateTable($data = null){ // insert, update or delete a row in a certain table
global $conn;
$data = SecureData( $data );
if( $data["action"] == "new" && !empty( $data["table"] ) ){
$rows = implode(", ", comillas(array_keys( $data["values"] ), "`") );
$values = implode(", ", comillas($data["values"]) );
$s = "INSERT INTO `". $data["table"]."`(". $rows .") VALUES(". $values .");";
// echo $s.'<br>'; return true;
$q = mysqli_query($conn, $s);
if( !$q ){

return false;
}
return mysqli_insert_id($conn);

答案 0 :(得分：0)
解决方案：在mysql中，将“email”字段添加为“unique”属性，这样只插入一次
