查询格式帮助 (PHP, MySQL) 遗留代码
Query formatting help (PHP, MySQL) Legacy code
此代码用于显示内容列表...
$result= mysql_query("
SELECT DISTINCT
m.username, m.asdf_txt, m.week_txt,
FROM table m
WHERE m.username='$user' ORDER BY m.week_txt ASC")
or die(mysql_error($link));
while($row = mysql_fetch_array($result)) {
echo "<br>" . $row['week_txt'] . "";
echo "<br>" . $row['asdf_txt'] . "";
}
echo "<br>"; echo "";
它最终显示
第 1 周
asdfasdf1
第 1 周
asdfasdf2
第 2 周
asdfasdf3
第 2 周
asdfasdf4
但我想改为...
第 1 周

任何建议都会有所帮助。我正在寻找一种将写入代码(php/mysql 文件)本身的解决方案。请记住,我之前已经使用以下代码以更迂回的方式解决了这个问题...
sed 's/<br>Week 1\b//2g; s/<br>Week 2//2g;'
试试这个
$prev = "";
while($row = mysql_fetch_array($result)) {
if (strcmp($row['week_text'],$prev)){
echo "<br>" . $row['asdf_txt'] . "";
} else {
echo "<br>" . $row['week_txt'] . "";
echo "<br>" . $row['asdf_txt'] . "";
}
$prev = $row['week_text'];
}
