如何利用PHP执行.SQL文件
本篇文章是对使用PHP执行 SQL文件的实现代码进行了详细的分析介绍 需要的朋友参考下
demo php:
复制代码 代码如下: ?php /** * 读取 sql 文件并写入数据库 * @version demo php */ class DBManager { var $dbHost = ; var $dbUser = ; var $dbPassword = ; var $dbSchema = ; function __construct($host $user $password $schema) { $this dbHost = $host; $this dbUser = $user; $this dbPassword = $password; $this dbSchema = $schema; } function createFromFile($sqlPath $delimiter = (;/n)|((;/r/n))|(;/r) $prefix = $menter = array( # )) { //判断文件是否存在 if(!file_exists($sqlPath)) return false; $handle = fopen($sqlPath rb ); $sqlStr = fread($handle filesize($sqlPath)); //通过sql语法的语句分割符进行分割 $segment = explode(";" trim($sqlStr)); //var_dump($segment); //去掉注释和多余的空行 foreach($segment as $statement) { $sentence = explode("/n" $statement); $newStatement = array(); foreach($sentence as $subSentence) { if( != trim($subSentence)) { //判断是会否是注释 $isComment = false; foreach($menter as $er) { if(eregi("^(" $er ")" trim($subSentence))) { $isComment = true; break; } } //如果不是注释 则认为是sql语句 if(!$isComment) $newStatement[] = $subSentence; } } $statement = $newStatement; } //对表名加前缀 if( != $prefix) { //只有表名在第一行出现时才有效 例如 CREATE TABLE talbeName $regxTable = "^[/`/ /"]{ }[/_a zA Z]+[/_a zA Z ]*[/`/ /"]{ }$";//处理表名的正则表达式 $regxLeftWall = "^[/`/ /"]{ }"; $sqlFlagTree = array( "CREATE" = array( "TABLE" = array( "$regxTable" = ) ) "INSERT" = array( "INTO" = array( "$regxTable" = ) ) ); foreach($segment as $statement) { $tokens = split(" " $statement[ ]); $tableName = array(); $this findTableName($sqlFlagTree $tokens $tableName); if(empty($tableName[ leftWall ])) { $newTableName = $prefix $tableName[ name ]; } else{ $newTableName = $tableName[ leftWall ] $prefix substr($tableName[ name ] ); } $statement[ ] = str_replace($tableName[ name ] $newTableName $statement[ ]); } } //组合sql语句 foreach($segment as $statement) { $newStmt = ; foreach($statement as $sentence) { $newStmt = $newStmt trim($sentence) "/n"; } $statement = $newStmt; } //用于测试 //var_dump($segment); //writeArrayToFile( data txt $segment); // self::saveByQuery($segment); return true; } private function saveByQuery($sqlArray) { $conn = mysql_connect($this dbHost $this dbUser $this dbPassword); mysql_select_db($this dbSchema); foreach($sqlArray as $sql) { mysql_query($sql); } mysql_close($conn); } private function findTableName($sqlFlagTree $tokens $tokensKey= $tableName = array()) { $regxLeftWall = "^[/`/ /"]{ }"; if(count($tokens)=$tokensKey) return false; if( == trim($tokens[$tokensKey])) { return self::findTableName($sqlFlagTree $tokens $tokensKey+ $tableName); } else { foreach($sqlFlagTree as $flag = $v) { if(eregi($flag $tokens[$tokensKey])) { if( ==$v) { $tableName[ name ] = $tokens[$tokensKey]; if(eregi($regxLeftWall $tableName[ name ])) { $tableName[ leftWall ] = $tableName[ name ]{ }; } return true; } else{ return self::findTableName($v $tokens $tokensKey+ $tableName); } } } } return false; } } function writeArrayToFile($fileName $dataArray $delimiter="/r/n") { $handle=fopen($fileName "wb"); $text = ; foreach($dataArray as $data) { $text = $text $data $delimiter; } fwrite($handle $text); } //测试 $dbM = new DBManager( localhost w f test ); $dbM createFromFile( data sql null fff_ ); ? lishixinzhi/Article/program/PHP/201311/21281

Q1: php 如何把一条sql语句写入数据库
?php
$dbhost = 'localhost:3306'; // mysql服务器主机地址
$dbuser = 'root'; // mysql用户名
$dbpass = '123456'; // mysql用户名密码
$conn = mysqli_connect($dbhost, $dbuser, $dbpass);
if(! $conn ){
die('连接失败: ' . mysqli_error($conn))
;}
echo '连接成功br /'; // 设置编码phpsql写入数据，防止中文乱码mysqli_query($conn , "set names utf8");
$runoob_title = '学习 Python';
$runoob_author = 'RUNOOB.COM';
$submission_date = '2016-03-06';
$sql = "INSERT INTO runoob_tbl ".
"(runoob_title,runoob_author, submission_date) ".
"VALUES ".
"('$runoob_title','$runoob_author','$submission_date')";
mysqli_select_db( $conn, 'RUNOOB' );$retval = mysqli_query( $conn, $sql );
if(! $retval ){
die('无法插入数据: ' . mysqli_error($conn))
;}
echo "数据插入成功\n";
mysqli_close($conn);

按照步骤开始phpsql写入数据，多看PHP手册。
Q2: php中使用sql语句写入数据，怎样在$_POST['ID']插入一个变量
改成{$_POST['Region'.$jc]},
原先phpsql写入数据的{$_POST['Region".$jc."']}phpsql写入数据，{}里的“”是相对独立的phpsql写入数据，不合外面的“”配对phpsql写入数据，也就是说“”就是单引号包含的一串字符串中的字符phpsql写入数据，所以，显而易见的PHP不会对".$jc."做concat处理，只是作为一串字符。
Q3: PHP+MSSQL是怎么写入数据的?
还是用mysql_query($sql)语句。
比如
$sql = "insert into tbl (id, name) values (1, 'abc')";
mysql_query($sql);
如果插入失败，返回值是false，否则返回插入纪录的条数。
