Replace HTML tag

[erme]

Hi,

 

I am including a file with PHP. The file contains basic html.

 

What I want is to be able replace a tag contained in this file with another one when outputted on the page I am including it on.

 

Eg: replace <h3>Title</h3> as in the file with <h1>Title</h1> on the page.

 

I have found this:

 

$str = str_replace(array('<h3>', '</h3>'), array('<h1>', '</h1>', $str);

 

But don't know how I would integrate it with my include:

 

<?php include('file.txt'); ?>

 

Many thanks

You would need to replace:

 

<?php include('file.txt'); ?>

 

With:

 

<?php
ob_start()
include('file.txt');
echo str_replace(array('<h3>', '</h3>'), array('<h1>', '</h1>', ob_get_clean());
?>

 

This puts the contents of the call to include within a buffer that you can then manipulate using whatever functions you like.

Thanks for your reply. I am now getting this error

 

unexpected T_INCLUDE

[trq]

Missing ; on

 

ob_start()

[erme]

After adding that it now comes up with

 

syntax error, unexpected ';'

 

on this line:

 

echo str_replace(array('<h3>', '</h3>'), array('<h1>', '</h1>', ob_get_clean());

echo str_replace(array('<h3>', '</h3>'), array('<h1>', '</h1>', ob_get_clean());

 

Are you missing a closing ) on the end?

These are simple syntax errors, you need to learn to fix them yourself.

 

echo str_replace(array('<h3>', '</h3>'), array('<h1>', '</h1>'), ob_get_clean());

[floridaflatlander]

syntax error, unexpected ';'

 

Usually means you need an extra closing parentheses or bracket or you have an extra parenthesis or bracket.

Thanks guys,

 

Unfortunately nothing is happening now. Just a blank screen. I am getting a warning though:

 

Warning: str_replace() expects at least 3 parameters, 2 given

[floridaflatlander]

is this another subject?

 

anyway three arguments str_replace("Replace this', 'With This', $in_this);

 

Did this come about after the above?

[erme]

I just don't seem to be achieving anything 

 

$thecontent = file_get_contents('textfile.txt');

echo str_replace('<h3>', '<h1>', $thecontent);

Tell a lie .. it works perfect. Thanks for all your help
