我试图将多行str保存到txt格式,然后使用gets函数进行访问,所以我试图用其他东西替换所有''n(例如#n)。由于某种原因,它不起作用。即使我在不同的搜索词上测试str_replace函数,它似乎也不起作用。知道为什么吗?
<?php
//define variables
$docRoot = $_SERVER["DOCUMENT_ROOT"];
$title = $_POST["title"];
$author = $_POST["author"];
$content = $_POST["content"];
$date = time();
//building post
str_replace("''n", "#n", $content);
$post = $date.' 't '.$title.' 't '.$author.' 't '.$content."'n";
//open and writing posts file
file_put_contents("$docRoot/ToDoProject/posts/posts.txt", $post, FILE_APPEND);
echo "<h1>Post uploaded!</h1>"
?>
Post从获取数据
<form class="form-horizontal" action="php/processpost.php" method="post">
<fieldset>
<!-- Form Name -->
<legend>Submit post</legend>
<!--Date -->
<?php
$date = date("H:i, dS F, Y");
echo "$date";
?>
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="title">Title</label>
<div class="col-md-4">
<input id="title" name="title" type="text" placeholder="" class="form-control input-md" required="">
</div>
</div>
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="author">Author</label>
<div class="col-md-4">
<input id="author" name="author" type="text" placeholder="hephaestus" class="form-control input-md" required="">
</div>
</div>
<!-- Textarea -->
<div class="form-group">
<label class="col-md-4 control-label" for="content">Content</label>
<div class="col-md-4">
<textarea class="form-control" id="content" name="content"></textarea>
</div>
</div>
<!--Submit Button -->
<button class="btn btn-primary btn-lg" type="submit" value="Submit Order" style="position: absolute; right: 2px;">
Submit</button>
</fieldset>
</form>
另外,我什么时候使用str_replace,什么时候使用prag_replace?如何在prag_replace中键入相同的代码?
错误在这一行:
//building post
str_replace("''n", "#n", $content);
您将换行符替换为#n,但不会将结果保存回$content。试试这个:
$content = str_replace("''n", "#n", $content);
