I am using simple-html-dom for my work. I want to get all PHP script (<?php ... ?>) form file using simple-html-dom.
if i have one file (name: text.php) with below code :
<html>
<head>
<title>Title</title>
</head>
<body>
<?php echo "This is test Text"; ?>
</body>
</html>
then how can i get this PHP script <?php echo "This is test Text"; ?> form above file of code using simple-html-dom.
$html = file_get_html('text.php');
foreach($html->find('<?php') as $element) {
//Sonthing code ...
}
i can not use like this, Is there any other option for this ?
Here's a solution using regex. Note that regex often is not advisable for parsing HTML files. That is, it might be okay in this case.
This will match each instance of a PHP code block and allow you to output (or do whatever else you want) either the entire block (including the tags) or the code that is contained within the block. See the documentation for preg_match_all().
<?php
$string = <<<'NOW'
<html>
<head>
<title>Title</title>
<?php echo "something else"; ?>
</head>
<body>
<?php echo "This is test Text"; ?>
</body>
</html>
NOW;
preg_match_all("/\<\?php (.*) \?\>/", $string, $matches);
foreach($matches[0] as $index => $phpBlock)
{
echo "Full block: " . $phpBlock;
echo "\n\n";
echo "Command: " . $matches[1][$index];
echo "\n\n";
}

I need to display html source code form other php file.
I have two file
code.php
index.php (I hope I can convert the code.php to html source code.)
code.php:
<!DOCTYPE html> <html> <body> <?php $color = "red"; echo $color; ?> </body> </html>
index.php (I hope I can convert the code.php to html source code.)
$php_to_html = file_get_contents("code.php");
$html_encoded = htmlentities($php_to_html);
echo $html_encoded;
but when i run the index.php file, the result is
<!DOCTYPE html> <html> <body> <?php $color = "red"; echo $color; ?> </body> </html>
but I hope I can see the result is
<!DOCTYPE html> <html> <body> red </body> </html>
any idea how can i do this ,thanks!!!
You want to execute the PHP, so include it and capture the output:
ob_start();
include("code.php");
$php_to_html = ob_get_clean();
$html_encoded = htmlentities($php_to_html);
echo $html_encoded;
If you want the HTML to be rendered as HTML then don't use htmlentities().
Optionally (not the best way) but you can execute it by retrieving from the URL:
$php_to_html = file_get_contents("http://www.example.com/code.php");
$html_encoded = htmlentities($php_to_html);
echo $html_encoded;
Buffer output and include it:
ob_start();
include_once('code.php');
$html = ob_get_clean();
By using output buffering, any output is not sent to the browser, but instead kept in memory. This allows you to run the code, and get the output as a variable. ob_get_clean() flushes the buffer (in this case into our $html variable), and then stops buffering, allowing you to continue as normal. :-)
I am trying to remove script tags from HTML using PHP but it doesn't work if there's HTML inside the javascript.
For example, if the script tags contain something like this:
function tip(content) {
$('<div id="tip">' + content + '</div>').css
It will stop at </div> and the rest of the script will still be taken into account.
This is what I have been using to remove the script tags:
foreach ($doc->getElementsByTagName('script') as $node)
{
$node->parentNode->removeChild($node);
}
How about some regex-based pre-processing?
Example input.html:
<html>
<head>
<title>My example</title>
</head>
<body>
<h1>Test</h1>
<div id="foo"> </div>
<script type="text/javascript">
document.getElementById('foo').innerHTML = '<span style="color:red;">Hello World!</span>';
</script>
</body>
</html>
Script tag removing php script:
<?php
// unformatted source output:
header("Content-Type: text/plain");
// read the example input file given above into a string:
$input = file_get_contents('input.html');
echo "Before:\r\n";
echo $input;
echo "\r\n\r\n-----------------------\r\n\r\n";
// replace script tags including their contents by ""
$output = preg_replace("~<script[^<>]*>.*</script>~Uis", "", $input);
echo "After:\r\n";
echo $output;
echo "\r\n\r\n-----------------------\r\n\r\n";
?>
You can use strip_tags function. In which you can allow the HTML attributes which you want allowed.
I think this is 'here and now' problem, and you need no something special. Just do something like this:
$text = file_get_content('index.html');
while(mb_strpos($text, '<script') != false) {
$startPosition = mb_strpos($text, '<script');
$endPosition = mb_strpos($text, '</script>');
$text = mb_substr($text, 0, $startPosition).mb_substr($text, $endPosition + 7, mb_strlen($text));
}
echo $text;
Only set encoding for 'mb_' like functions
I have already search about this question,I want to remove line break from the html,but there a some split php line in the html file,for example:
<html>
<head>
<title><?='abc'?></title>
</head>
<?php
if($_SESSION['test'] == 'yes'){
echo 'hello';
}
?>
123456
43567
<?='13245tryt57u68'?>
</body>
</html>
how can I remove line break from this php file?
You could use ob_start();
<?php ob_start();
//Start page output
?>
<html>
<head>
<title><?='abc';?></title>
</head>
<body>
<?php
if(isset($_SESSION['test']) && $_SESSION['test'] == 'yes'){
echo 'hello';
}
?>
123456
43567
<?='13245tryt57u68';?>
</body>
</html>
<?php
//End page output and assign the contents to a variable
$buffer = ob_get_contents();
ob_end_clean();
//Replace the new line with null
echo str_replace("\n",null,$buffer);
?>
Result:
<html><head><title>abc</title></head><body>1234564356713245tryt57u68</body></html>
If you want it in your IDE:
Use replace function, and replace \n by no character
If you want it for the client:
You have to configure your htaccess to remove the lines breaks/indenting when sending the file to the client, ie by using the mod_pagespeed extension:
http://www.the-art-of-web.com/system/mod-pagespeed-settings/ and the collapse_whitespace option
I am requesting the source code of a website like this:
<? $txt = file_get_contents('http://stats.pingdom.com/qmwwuwoz2b71/522741');
echo $txt; ?>
Bu I would like to replace the relative links with absolute ones! Basically,
<img src="/images/legend_15s.png"/> and <img src='/images/legend_15s.png'/>
should be replaced by
<img src="http://domain.com/images/legend_15s.png"/>
and
<img src='http://domain.com/images/legend_15s.png'/>
respectively. How can I do this?
This can be acheived with the following:
<?php
$input = file_get_contents('http://stats.pingdom.com/qmwwuwoz2b71/522741');
$domain = 'http://stats.pingdom.com/';
$rep['/href="(?!https?:\/\/)(?!data:)(?!#)/'] = 'href="'.$domain;
$rep['/src="(?!https?:\/\/)(?!data:)(?!#)/'] = 'src="'.$domain;
$rep['/#import[\n+\s+]"\//'] = '#import "'.$domain;
$rep['/#import[\n+\s+]"\./'] = '#import "'.$domain;
$output = preg_replace(
array_keys($rep),
array_values($rep),
$input
);
echo $output;
?>
Which will output links as follows:
/something
will become,
http://stats.pingdom.com//something
And
../something
will become,
http://stats.pingdom.com/../something
But it will not edit "data:image/png;" or anchor tags.
I'm pretty sure the regular expressions can be improved though.
This code replaces only the links and images:
<? $txt = file_get_contents('http://stats.pingdom.com/qmwwuwoz2b71/522741');
$txt = str_replace(array('href="', 'src="'), array('href="http://stats.pingdom.com/', 'src="http://stats.pingdom.com/'), $txt);
echo $txt; ?>
I have tested and its working :)
UPDATED
Here is done with regular expression and working better:
<? $txt = file_get_contents('http://stats.pingdom.com/qmwwuwoz2b71/522741');
$domain = "http://stats.pingdom.com";
$txt = preg_replace("/(href|src)\=\"([^(http)])(\/)?/", "$1=\"$domain$2", $txt);
echo $txt; ?>
Done :D
You dont need php, you only need to use the html5 base tag, and put your php code in html body, you only need to do the following
Example :
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<base href="http://yourdomain.com/">
</head>
<body>
<? $txt = file_get_contents('http://stats.pingdom.com/qmwwuwoz2b71/522741');
echo $txt; ?>
</body>
</html>
and all the files will use the absolute url
I know in php you can embed variables inside variables, like:
<? $var1 = "I\'m including {$var2} in this variable.."; ?>
But I was wondering how, and if it was possible to include a function inside a variable.
I know I could just write:
<?php
$var1 = "I\'m including ";
$var1 .= somefunc();
$var1 = " in this variable..";
?>
But what if I have a long variable for output, and I don't want to do this every time, or I want to use multiple functions:
<?php
$var1 = <<<EOF
<html lang="en">
<head>
<title>AAAHHHHH</title>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
</head>
<body>
There is <b>alot</b> of text and html here... but I want some <i>functions</i>!
-somefunc() doesn't work
-{somefunc()} doesn't work
-$somefunc() and {$somefunc()} doesn't work of course because a function needs to be a string
-more non-working: ${somefunc()}
</body>
</html>
EOF;
?>
Or I want dynamic changes in that load of code:
<?
function somefunc($stuff) {
$output = "my bold text <b>{$stuff}</b>.";
return $output;
}
$var1 = <<<EOF
<html lang="en">
<head>
<title>AAAHHHHH</title>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
</head>
<body>
somefunc("is awesome!")
somefunc("is actually not so awesome..")
because somefunc("won\'t work due to my problem.")
</body>
</html>
EOF;
?>
Well?
Function calls within strings are supported since PHP5 by having a variable containing the name of the function to call:
<?
function somefunc($stuff)
{
$output = "<b>{$stuff}</b>";
return $output;
}
$somefunc='somefunc';
echo "foo {$somefunc("bar")} baz";
?>
will output "foo <b>bar</b> baz".
I find it easier however (and this works in PHP4) to either just call the function outside of the string:
<?
echo "foo " . somefunc("bar") . " baz";
?>
or assign to a temporary variable:
<?
$bar = somefunc("bar");
echo "foo {$bar} baz";
?>
"bla bla bla".function("blub")." and on it goes"
Expanding a bit on what Jason W said:
I find it easier however (and this works in PHP4) to either just call the
function outside of the string:
<?
echo "foo " . somefunc("bar") . " baz";
?>
You can also just embed this function call directly in your html, like:
<?
function get_date() {
$date = `date`;
return $date;
}
function page_title() {
$title = "Today's date is: ". get_date() ."!";
echo "$title";
}
function page_body() {
$body = "Hello";
$body = ", World!";
$body = "\n\n";
$body = "Today is: " . get_date() . "\n";
}
?>
<html>
<head>
<title><? page_title(); ?></title>
</head>
<body>
<? page_body(); ?>
</body>
</html>
