如果在php中搜索匹配,则在表中显示
请参阅我从dat文件在php中的搜索,这是我迄今为止的代码:如果在php中搜索匹配,则在表中显示,php,Php,请参阅我从dat文件在php中的搜索,这是我迄今为止的代码: <?php if (isset($_POST["name"])) { $file = 'order.dat'; $searchfor = $_POST["name"]; // the following line prevents the browser from parsing this as HTML. // get the file contents, assuming the file t
<?php
if (isset($_POST["name"]))
{
$file = 'order.dat';
$searchfor = $_POST["name"];
// the following line prevents the browser from parsing this as HTML.
// get the file contents, assuming the file to be readable (and exist)
$contents = file_get_contents($file);
// escape special characters in the query
$pattern = preg_quote($searchfor, '/');
//$pattern = "/^$pattern/m"; // your string starts with $pattern (177)
$pattern = "/^$pattern.*$/m";
// search, and store all matching occurences in $matches
if(preg_match_all($pattern, $contents, $matches)){
echo "Found matches:\n";
echo implode("\n", $matches[0]);
}
else{
echo "No matches found";
}
}
?>
<h3>Search Order Details</h3>
<form method="post" action="search.php" id="searchform">
<input type="text" name="name">
<input type="submit" name="submit" value="Search">
</form>
现在,如果搜索被找到,它会说找到了匹配项。。。就像我输入177它给出的
找到匹配项:177 | RC4564177 | 54156456465 | 129$
现在如果我输入002,它会显示找不到匹配项
如果搜索匹配,我希望在此表中显示:-
<table>
<tr>
<th>Order number </th>
<th>Tranasaction id</th>
<th>Date </th>
<th>Total Price</th>
</tr>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
</table>

您必须使用fopen
或file\u获取内容
打开文件,然后在换行符\n
或\r\n
上进行分解
或拆分(取决于操作系统和文件)
然后,您可以循环遍历它们并再次分解该字符串,以查看第一个元素是否是您要查找的元素。像这样:
$resLines = explode("\n", $FileContents);
foreach ($resLines as $line) {
$resLine = explode("|", $line);
if ($resLine[0] == $Search) {
echo "Found! $line";
}
}
关于编辑的更新
应该是这样的:
$resContents = file_get_contents("order.dat");
$resLines = explode("\n", $FileContents);
foreach ($resLines as $line) {
$resLine = explode("|", $line);
if ($resLine[0] == $Search) {
$aFound = $resLine; // setting our array with the found contents
}
}
echo "
<table>
<tr>
<th>Order number </th>
<th>Tranasaction id</th>
<th>Date </th>
<th>Total Price</th>
</tr>
<tr>
<td>" . $aFound[0] . "</td>
<td>" . $aFound[1] . "</td>
<td>" . $aFound[2] . "</td>
<td>" . $aFound[3] . "</td>
</tr>
</table>";
$resContents=文件获取内容(“order.dat”);
$resLines=explode(“\n”,$FileContents);
foreach($resline作为$line){
$resLine=分解(“|”,$line);
如果($resLine[0]==$Search){
$aFound=$resLine;//使用找到的内容设置数组
}
}

不确定您的问题到底是什么?@David我也不知道您的问题是什么。@Pekka请看,如果搜索匹配,我想将我的数据放在表中。。。比如,如果我输入177,它会给出找到的匹配项:177 | RC456456177 | 54156465 | 129$,现在我想把这些细节放在表中。。。表示如果搜索匹配,我想在表中显示…@Devator:)。。然后,在我想在表中显示详细信息之后,否则现在找不到匹配项,会出现匹配项警报,但我想在表中显示177 | rc456177 | 54156465 | 129$。@Pekka:)现在再次编辑问题以便更好地理解:)我不明白你在说什么。。。你可以在任何编辑器中修改我的代码,但仍然不能显示在表中
$resContents = file_get_contents("order.dat");
$resLines = explode("\n", $FileContents);
foreach ($resLines as $line) {
$resLine = explode("|", $line);
if ($resLine[0] == $Search) {
$aFound = $resLine; // setting our array with the found contents
}
}
