Append html code to file using PHP
Question
I have a Javascript function that takes a string and sends it via ajax to a PHP page. In PHP I would put this string inside the head tag (that already exist) of an html file. This change should be final. How could I do this? I don't know how to manipulate html code via PHP.

如果您不能使用JS，则只需使用if / else语句，并从ajax向您的标签回显字符串。

One way around this would be to use file_get_contents, then do a string replace on the tag with the amended code, and then write the changes with the ammended code.
Example
<?php
$file = "myhtmlfile.html";
$original = file_get_contents($file);
$needle = "<head>";
$new_content = "<head>\n".$_POST['header'];
$replacement = str_replace($needle, $new_content, $original);
file_put_contents($replacement, $file);
?>

<?php
$htmlpage = file_get_contents('http://example.com/index.html');
echo str_replace("<head>", "<head>New text", $htmlpage);
//the result should be from <body></body> to <body>New Text</body>
?>
Also if you have text between body tags you can include it in
str_replace("<body>Old Text", "<body>New Text", $htmlpage)
If you have the string inside a varibale or you are using $_POST then instead of "<head>New text" put "<head>".$_POST['thestring']
