从MySql到Excel的PHP select语句。 格式化date为YYYYMMDD
注意：在MySql数据库中，“dob”是varchar，格式为：mm / dd / yyyy
出生date，Cvrg生效date和Cvrg到期date需要在到达Excel时从mm / dd / yyyy更改为yyyymmdd。 请参阅下面的代码：
<?php if($qry == "ok"){ // get db connection include("connection string goes here"); $select = "SELECT 'A' AS 'Transaction Type', policyno AS 'UHCSR Policy No', school AS 'Campus Location Description', Code AS 'Campus Location Number', '' AS 'Date Received by UHCSR', '' AS 'Date Stamped By School', '' AS 'Social Security Number', SSN AS 'StudentID Number', lname AS 'LastName', fname AS 'FirstName', mi AS 'Middle Initial', dob AS 'Date of Birth', gender AS 'Gender', concat( concat(address1, ' '), address2) AS '(Mailing) Address Ln 1','' AS '(Mailing) Address Ln 2',city AS '(Mailing) City', state AS '(Mailing) State', zipcode AS '(Mailing) ZipCode', '' AS '(Mailing) ZipCode Suffix', '' AS '(Permanent) Address Ln 1', '' AS '(Permanent) Address Ln 2', '' AS '(Permanent) City', '' AS '(Permanent) State', '' AS '(Permanent) ZipCode', '' AS '(Permanent) ZipCode Suffix', email AS 'Email Address', replace(phone, '-', '') AS 'Telephone Number', 'ITL' AS 'Insured Category Code', '' AS 'Insured Type Code', 'A' AS 'Insured (Row)ID Code', period AS 'Period Code', semester AS 'Cvrg Period Description', trim(left(coveragedate, locate('-', coveragedate)-1)) AS 'Cvrg Effective Date', trim(replace(right(coveragedate, locate('-', coveragedate)+0),'-','')) AS 'Cvrg Expiration Date', noadfee AS 'Premium Amount', quantity AS 'Coverage Period Quantity', '' AS 'Primary Insured SSN', SSN AS 'Primary Insured Student ID', '' AS 'Organization Name', '' AS 'Organization Number', '' AS 'Dependent Coverage Code', '' AS 'Check Number', '' AS 'Credit Card Number', '' AS 'Credit Card Expiration Month', '' AS 'Credit Card Expiration Year', tedfee AS 'Amount Paid', paytype AS 'Pay Type' FROM intenrollment WHERE confirm = 'Y' and amountpaid != '0' and (policyno LIKE '%200473-%' OR policyno LIKE '%2060-%' OR policyno LIKE '%202377-%' or policyno='')"; if ( $smon != "None" and $sday != "None" and $syear != "None" and $emon != "None" and $eday != "None" and $eyear != "None" ) { $startdate = strtotime("$smon $sday, $syear"); $enddate = strtotime("$emon $eday, $eyear"); $select .= "AND applydate BETWEEN $startdate AND $enddate "; } elseif ( $smon != "None" and $sday != "None" and $syear != "None" ) { $startdate = strtotime("$smon $sday, $syear"); $select .= "AND applydate > $startdate "; } elseif ( $emon != "None" and $eday != "None" and $eyear != "None" ) { $enddate = strtotime("$emon $eday, $eyear"); $select .= "AND applydate < $enddate "; } $select .= "ORDER BY school ASC, lname ASC"; // run query $export = mysql_query($select) or die(mysql_error()); $fields = mysql_num_fields($export); // get field info for headers $header = ''; for ( $i = 0; $i < $fields; $i++ ) { $header .= mysql_field_name($export, $i) .

// convert old date string to YYYYmmdd format $date = date('Ymd', strtotime($old_date_string));
你可以使用mysql的date_format函数就好
DATE_FORMAT(dob,'%Y%m%d') AS 'Date of Birth',

编辑：becouse dob是varchar你应该检查它在foreach中，只是使用string函数或cballou的答案将为你工作
foreach ( $row as $key => $value ) { if ( ( !isset($value) ) OR ( $value == "" ) ) { $value = "\t"; } else { if($key == 'Date of Birth') { $exploded_value = explode("/",$value); $value = $value[2].$value[0].$value[1]; // or according to cballou's answer //$value = date('Ymd',strtotime($value)); } $value = str_replace('"', '""', $value); $value = '="' . $value . '"' . "\t"; // ^ // Added an equal sign } $line .= $value; }
