I have this:
ob_start(); ?>
<div class="" id="loading">
<?php echo file_get_contents($page["texto"]) ?>
</div> <?php
$content = ob_get_clean();
But I would like to have that template html in a separate file, just like:
$content = file_get_contents('cms/template.php');
Now this won't work because it has php tags inside and when retrieving the string it gets as
how can I achieve this without using a dirty hack like:
$pre = file_get_contents('part1');
$var = file_get_contents($page["texto"]);
$post = file_get_contents('part2');
And adding all them...
It's still hack, but unless you use a templating system like Twig you have no choice:
ob_start();
include 'cms/template.php';
$content = ob_get_clean();
echo $content;
ob_start enables output buffering so nothing gets sent to the browser. We then include the file which will execute PHP normally. We then use ob_get_clean to get the contents of the output buffer (which is your template file). and disable the output buffer, discarding it's contents, as we have the contents in $content.

I am trying to make "manner friendly" website. We use different declination dependent on gender and other factors. For example:
You did = robili
It did = robilo
She did = robila
Linguisticaly this is very simplified (and unlucky) example! I would like to change html text in php file where appropriate. For example
<? php
something
?>
html text of the page and somewhere is the word "robil"
<div>we tried to robil^i|o|a^</div>
<? php something ?>
Now I would like to replace all occurences of different tokens ^characters|characters|characters^ and replace them by one of their internal values according to "gender".
It is easy in javascript on the client side, but you will see all this weird "tokenizing" before javascript replace it.
Here I do not know the elegant solution.
Or do you have better idea?
Thanks for advice.
You can add these scripts before and after the HTML:
<?php
// start output buffering
ob_start();
?>
<html>
<body>
html text of the page and somewhere is the word "robil"
<div>we tried to robil^i|o|a^, but also vital^si|sa|ste^, borko^mal|mala|malo^ </div>
</body>
</html>
<?php
$use = 1; // indicate which declination to use (0,1 or 2)
// get buffered html
$html = ob_get_contents();
ob_end_clean();
// match anything between '^' than's not a control chr or '^', min 5 and max 20 chrs.
if (preg_match_all('/\^[^[:cntrl:]\^]{3,20}\^/',$html,$matches))
{
// replace all
foreach (array_unique($matches[0]) as $match)
{
$choices = explode('|',trim($match,'^'));
$html = str_replace($match,$choices[$use],$html);
}
}
echo $html;
This returns:
html text of the page and somewhere is the word "robil" we tried to
robilo, but also vitalsa, borkomala
I want to pass multiple variable to Mail template page and echo to that page using phpmailer library.
I have two variables to pass welcome.php page and echo there.
$name = 'example';
$email = 'example#mail.com';
I have use this code
$mail->MsgHTML(str_replace('[emailhere]', $email, file_get_contents('welcome.php')), dirname(__FILE__));
You can send arrays to str_replace to replace multiple values.
For example:
$message = str_replace(
array(
'[emailhere]',
'[namehere]'
),
array(
$email,
$name
),
file_get_contents('welcome.php')
);
By the way, you should probably not give your template a php extension as it will parse any php if you call or include it directly. So that could be a security risk if users can modify templates.
You may use output buffering.
Echo variables on your template file ($template):
for ex:
<p><?=$name?></p>
Then include it and pass through output buffering
ob_start(); //Start output buffering
include('welcome.php'); //include your template file
$template = ob_get_clean(); //Get current buffer contents and delete current output buffer
$mail->msgHTML($template); // Add html content into your PHP MAILER class
I am using php, I want to get the content from url in faster way.
Here is a code which I use.
Code:(1)
<?php
$content = file_get_contents('http://www.filehippo.com');
echo $content;
?>
Here is many other method to read files like fopen(), readfile() etc. But I think file_get_contents() is faster than these method.
In my above code when you execute it you see that it give every thing from this website even images and ads. I want to get only plan html text no css-style, images and ads. How can I get this.
See this to understand.
CODE:(2)
<?php
$content = file_get_contents('http://www.filehippo.com');
// do something to remove css-style, images and ads.
// return the plain html text in $mod_content.
echo $mod_content;
?>
If I do that like above then I am going in wrong way, because I already get the full content in variable $content and then modify it.
Can here is any function method or anything else which get the directly plain html text from url.
Below code is written only to understanding, this is not the original php code.
IDEAL CODE:(3);
<?php
$plain_content = get_plain_html('http://www.filehippo.com');
echo $plain_content; // no css-style, images and ads.
?>
If I can get this function it will be much faster than others. Can it is possible.
Thanks.
Try this.
$content = file_get_contents('http://www.filehippo.com');
$this->html = $content;
$this->process();
function process(){
// header
$this->_replace('/.*<head>/ism', "<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE html PUBLIC '-//WAPFORUM//DTD XHTML Mobile 1.0//EN' 'http://www.wapforum.org/DTD/xhtml-mobile10.dtd'><html xmlns='http://www.w3.org/1999/xhtml'><head>");
// title
$this->_replace('/<head>.*?(<title>.*<\/title>).*?<\/head>/ism', '<head>$1</head>');
// strip out divs with little content
$this->_stripContentlessDivs();
// divs/p
$this->_replace('/<div[^>]*>/ism', '') ;
$this->_replace('/<\/div>/ism','<br/><br/>');
$this->_replace('/<p[^>]*>/ism','');
$this->_replace('/<\/p>/ism', '<br/>') ;
// h tags
$this->_replace('/<h[1-5][^>]*>(.*?)<\/h[1-5]>/ism', '<br/><b>$1</b><br/><br/>') ;
// remove align/height/width/style/rel/id/class tags
$this->_replace('/\salign=(\'?\"?).*?\\1/ism','');
$this->_replace('/\sheight=(\'?\"?).*?\\1/ism','');
$this->_replace('/\swidth=(\'?\"?).*?\\1/ism','');
$this->_replace('/\sstyle=(\'?\"?).*?\\1/ism','');
$this->_replace('/\srel=(\'?\"?).*?\\1/ism','');
$this->_replace('/\sid=(\'?\"?).*?\\1/ism','');
$this->_replace('/\sclass=(\'?\"?).*?\\1/ism','');
// remove coments
$this->_replace('/<\!--.*?-->/ism','');
// remove script/style
$this->_replace('/<script[^>]*>.*?\/script>/ism','');
$this->_replace('/<style[^>]*>.*?\/style>/ism','');
// multiple \n
$this->_replace('/\n{2,}/ism','');
// remove multiple <br/>
$this->_replace('/(<br\s?\/?>){2}/ism','<br/>');
$this->_replace('/(<br\s?\/?>\s*){3,}/ism','<br/><br/>');
//tables
$this->_replace('/<table[^>]*>/ism', '');
$this->_replace('/<\/table>/ism', '<br/>');
$this->_replace('/<(tr|td|th)[^>]*>/ism', '');
$this->_replace('/<\/(tr|td|th)[^>]*>/ism', '<br/>');
// wrap and close
}
private function _replace($pattern, $replacement, $limit=-1){
$this->html = preg_replace($pattern, $replacement, $this->html, $limit);
}
for more - https://code.google.com/p/phpmobilizer/
you can use regular expression to delete css-script's tags and image's tags, just replace those codes with blank space
preg_replace($pattern, $replacement, $string);

Thank you for answering my question so quickly. I did some more digging and ultimately found a solution for grabbing data from external file and specific div and posting it into another document using PHP DOMDocument. Now I'm looking to improve the code by adding an if condition that will grab data from a different div if the one called for initially by getElementById has now data. Here is the code for what I got so far.
External html as source.
<div id="tab1_header" class="cushycms"><h2>Meeting - 12:00pm to 3:00pm</h2></div>
My PHP file calling from source looks like this.
<?php
$source = "user_data.htm";
$dom = new DOMDocument();
$dom->loadHTMLFile($source);
$dom->preserveWhiteSpace = false;
$tab1_header = $dom->getElementById('tab1_header');
?>
<html>
<head>
<title></title>
</head>
<body>
<div><h2><?php echo $tab1_header->nodeValue; ?></h2></div>
</body>
</html>
The following function will output a message if a div id can't be found but...
if(!tab1_header)
{
die("Element not found");
}
I would like to call for a different div if the one called for initially has no data. Meaning if <div id="tab1_header"></div> then grab <div id="alternate"><img src="filler.png" /></div>. Can someone help me modify the function above to achieve this result.
Thanks.
either split up master.php so div1\2 are in a file each or set them each to a var, them include master.php, and use the appropriate variable
master.php
$d1='<div id="description1">Some Text</div>';
$d2='<div id="description2">Some Text</div>';
description1.php
include 'master.php';
echo $d1;
You can't do this solely with PHP includes unless you put the divs into separate files. Look into PHP templating; it's probably the best solution for this. Or, since you're new to the language, try using variables:
master.php
$description1 = '<div id="description1">Some Text</div>';
$description2 = '<div id="description2">Some Text</div>';
board1.php
include 'master.php';
echo $description1;
board2.php
include 'master.php';
echo $description2;
Alternatively, you could use JavaScript, but that might get a little messy.
Short answer is: although it's possible it's probably very bad idea taking this approach.
Longer answer: the solution may turn out to be too complicated. If in your master.php file is only HTML markup, you could read content of that file with file_get_contents() function and then parse it (i.e. with DOMDocument library functions). You would have to look for a div with given id.
$doc = new DOMDocument();
$doc->loadHTMLFile($file);
$divs = $doc->getElementsByTagName('div');
foreach ($divs as $div)
{
if( $div->getAttribute('id') == 'description1' )
{
echo $div->nodeValue."\n";
}
}
?>
If your master.php file has also some dynamic content you could do following trick:
<?php
ob_start();
include('master.php');
$sMasterPhpContent = ob_get_clean();
// same as above - parse HTML
?>
Edit:
$tab_header = $dom->getElementById('tab1_header') ? $dom->getElementById('tab1_header') : $dom->getElementById('tab2_header');
Is there any way for all my PHP and/or HTML file output to be "filtered" before being displayed in the browser? I figured that I could pass it through a global function before it is displayed but I'm stuck on the implementation. Please help.
If there is a better way to achieve the same result, I'd be happy to know.
Thanks.
Check out ob_start which lets you pass a callback handler for post-processing your script output.
For example, PHP includes a built-in callback ob_gzhandler for use in compressing the output:
<?php
ob_start("ob_gzhandler");
?>
<html>
<body>
<p>This should be a compressed page.</p>
</html>
<body>
Here's a fuller example illustrating how you might tidy your HTML with the tidy extension:
function tidyhtml($input)
{
$config = array(
'indent' => true,
'output-xhtml' => true,
'wrap' => 200);
$tidy = new tidy;
$tidy->parseString($input, $config, 'utf8');
$tidy->cleanRepair();
// Output
return $tidy;
}
ob_start("tidyhtml");
//now output your ugly HTML
If you wanted to ensure all your PHP scripts used the same filter without including it directly, check out the auto_prepend_file configuration directive.
You can use output buffering and specify a callback when you call ob_start()
<?php
function filterOutput($str) {
return strtoupper($str);
}
ob_start('filterOutput');
?>
<html>
some stuff
<?php echo 'hello'; ?>
</html>
You can use PHP's output buffering functions to do that
You can provide a callback method that is called when the buffer is flushed, like:
<?php
function callback($buffer) {
// replace all the apples with oranges
return (str_replace("apples", "oranges", $buffer));
}
ob_start("callback");
?>
<html>
<body>
<p>It's like comparing apples to oranges.</p>
</body>
</html>
<?php
ob_end_flush();
?>
In that case output is buffered instead of sent from the script and just before the flush your callback method is called.
Have a look at using Smarty. It's a templating system for PHP, that is good practice to use, and into which you can plug global output filters.
edit: Paul's reply is better. So it would be
ob_start("my_filter_function");
My original reply was:
That can be achieved with output buffering.
For example:
ob_start();
// Generate all output
echo "all my output comes here."
// Done, filtering now
$contents = ob_get_contents();
ob_end_clean();
echo my_filter_function($contents);
