我有一些句子。我必须选择包含超过 6 个单词的句子。然后它们将被插入到数据库中。
<?php
require_once 'conf/conf.php';
$text = " Poetry. Do you read poetry while flying? Many people find it relaxing to read on long flights. Poetry can be divided into several genres, or categories. ";
$sentences = explode(".", $text);
foreach ($sentences as $sentence) {
if (count(preg_split('/\s+/', $sentence)) > 6) {
$save = $sentence. ".";
$sql = mysql_query("INSERT INTO tb_name VALUES('','$save')");
}
}
?>
结果只是插入数据库的第二句话 => '你在飞行时读诗吗？许多人发现在长途飞行中阅读可以放松身心。而第三句也应插入。请帮助我，谢谢 :)
最佳答案
这是您正在寻找的解决方案。您不能添加多行，因为您的 ID 值未指定并且它是表中的键。由于要将句子添加到同一行，因此需要执行一次查询。
$text = " Poetry. Do you read poetry while flying? Many people find it relaxing to read on long flights. Poetry can be divided into several genres, or categories. ";
$sentences = explode(".", $text); $save = array();
foreach ($sentences as $sentence) {
if (count(preg_split('/\s+/', $sentence)) > 6) {
$save[] = $sentence. ".";
}
}
if( count( $save) > 0) {
$sql = mysql_query("INSERT INTO tb_name VALUES('','" . implode( ' ', $save) . "')");
}
现在，这两个句子将被插入到数据库中的同一行中，以空格分隔。如果将第一个参数修改为 implode()，则可以更改它们的分隔符。
生成的查询是这样的:
INSERT INTO tb_name VALUES('',' Do you read poetry while flying? Many people find it relaxing to read on long flights. Poetry can be divided into several genres, or categories.')
