I'm trying to convert my sample HTML output into a plain text but I don't know how. I use file_get_contents but the page which I'm trying to convert returns most like the same.
$raw = "http://localhost/guestbook/profiles.php";
$file_converted = file_get_contents($raw);
echo $file_converted;
profiles.php
<html>
<head>
<title>Profiles - GuestBook</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
<!-- Some Divs -->
<div id="profile-wrapper">
<h2>Profile</h2>
<table>
<tr>
<td>Name:</td><td> John Dela Cruz</td>
</tr>
<tr>
<td>Age:</td><td>15</td>
</tr>
<tr>
<td>Location:</td><td> SomewhereIn, Asia</td>
</tr>
</table>
</div>
</body>
</html>
Basically, I trying to echo out something like this (plain text, no styles)
Profile
Name: John Dela Cruz
Age: 15
Location: SomewhereIn, Asia
but i don't know how. :-( . Please help me guys , thank you in advance.
EDIT: Since i am only after of the content of the page, no matter if it's styled or just a plain text , is there a way to select only (see code below) using file_get_contents() ?
<h2>Profile</h2>
<table>
<tr>
<td>Name:</td><td> John Dela Cruz</td>
</tr>
<tr>
<td>Age:</td><td>15</td>
</tr>
<tr>
<td>Location:</td><td> SomewhereIn, Asia</td>
</tr>
</table>
Use php strip_tags
If strip_tags is not working for then maybe you can use regex to extract the info you want.
Try using PHP preg_match with /(<td>.*?<\/td>)/ as the pattern
Have a look at simplexml_load_file():
http://www.php.net/manual/en/function.simplexml-load-file.php
It will allow you to load the HTML data into an object (SimpleXMLElement) and traverse that object like a tree.
try to use PHP function strip_tags
try this one,
<?php
$data = file_get_contents("your_file");
preg_match_all('|<div[^>]*?>(.*?)</div>|si',$data, $result);
print_r($result[0][0]);
?>
I have try this one, and it seems work for me, for you too i hope
You can use the strip_tags php function for this. Browse through the comments in the php manual page of the strip_tags function to see how you can use this in a good way.

I'm using a program I made to scrape a file for text and parse the information into a ini file. I asked a question here earlier asking about parse_ini_file and why I could not use the indexes and someone gave me a way to loop through using this.
$ini_array = parse_ini_file("myfile.ini", true
foreach($ini_array as $key=>$value)
I then echo out the result echo ($value['Username']) . " "; and store it into the table. I have the table functioning link here, http://liveviewtest.byethost7.com/index.php but the plugin I'm using is not functioning as intended. The sorting does not work, and I'm wondering is it because the data type? http://www.datatables.net/manual/data tells you that the accepted data types are arrays, objects, and instances. My question is what would be the best way for me to convert this into one of these data types? I'm new to php / html so sorry if this is basic.
Php File http://pastebin.com/VRUHLdMQ
Ini File http://pastebin.com/yZsg16qA
Your table is being generated so PHP & Ini file are fine but HTML code you are generating is incorrect so either DataTable plugin or jQuery DOM parser is confused.
Please fix it and it should work fine.
Put jquery+datatables js/css into <head> section.
You use multiple <tbody> and you put </tr> after </tbody>
So basically you shoud put echo "</tbody>"; outside loop so
echo "<tbody>"; // <<< HERE
foreach ($ini_array as $key => $value) {
echo "<tr>";
for ($i = 0; $i < 12; $i++) {
echo "<td>";
echo ($value[$getstats[$i]]);
echo "</td>";
}
echo "</tr>";
}
echo "</tbody>"; // <<< HERE
I'm wondering is it because the data type? http://www.datatables.net/manual/data tells you that the accepted data types are arrays, objects, and instances.
No, your code its fine as manual says Data can be read from DOM. You need arrays/objects/instances if you create table straight from javascript.
See below:
DOM
When DataTables starts up, it will automatically check the table it is operating on for data that already exists inside it and use it for the table (note that it will throw this data away if you pass in data using data or ajax to get new data!). This is the simplest method of using DataTables - working with a regular HTML table.
Note that when using a DOM sourced table, DataTables will use arrays as the data source (see above) by default, although you could use the columns.data option to have it construct objects for the row data instead.
http://www.datatables.net/manual/data#DOM
Your table structure was not correct :

hi guys, im trying to use barryvdh/laravel-dompdf, everything works fine except i cant load my data to the view to dynamically produce content, i keep getting 'Undefined variable: data'
here is my code:
$data =[
'fname'=>Input::get('efname'),
'lname'=>Input::get('elname'),
'dob'=>Input::get('edob'),
'reg_date'=>date('Y-m-d'),
'email'=>Input::get('eemailaddrs'),
'gender'=>Input::get('gender'),
'mobile'=>Input::get('emobile'),
'p_addrss'=>Input::get('epaddress'),
'c_addrss'=>Input::get('ecaddress'),
'quals'=>Input::get('quali'),
'pdfname'=>$pdfname,
'empId'=>Input::get('employeeId'),
];
return PDF::loadView('employee/generatepdf',$data)
->save(public_path().'/pdfs/'.$pdfname.'.pdf');
its going to pdf template page..But cant get the array values.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<img align="center" src="{{public_path()}}/assets/img/logo.png">

<td style="width:50%">:{{$data['fname']}} {{$data['lname']}}</td>
</tr>
</table>
</body>
</html>
also not taking css rules into pdf file.
How can i solve this issue...?
Thanks
You can check if array contain data or not by :
$data =[
'fname'=>Input::get('efname'),
'lname'=>Input::get('elname'),
'dob'=>Input::get('edob'),
'reg_date'=>date('Y-m-d'),
'email'=>Input::get('eemailaddrs'),
'gender'=>Input::get('gender'),
'mobile'=>Input::get('emobile'),
'p_addrss'=>Input::get('epaddress'),
'c_addrss'=>Input::get('ecaddress'),
'quals'=>Input::get('quali'),
'pdfname'=>$pdfname,
'empId'=>Input::get('employeeId'),
];
dd($data);
return PDF::loadView('employee/generatepdf',$data)->save(public_path().'/pdfs/'.$pdfname.'.pdf');
just try it and you will find if your array contain data or not
Try like that,
Use an array as second argument for the view.
return PDF::loadView('employee/generatepdf',array('data'=>$data));
You need to pass $data variable using compact() function
return PDF::loadView('employee/generatepdf',compact('data'))
->save(public_path().'/pdfs/'.$pdfname.'.pdf');
I want to write some html code in php. In this html code I am calling a javascript function. but while it is calling the function there is a problem. I think the problem is quotes but I couldn't fix it.
This is the html code that I want to put inside php.
<table>
<tr>
<img src="s.png" name="img">
</tr>
</table>
and this is my javascript code;
<script type="text/javascript">
img1 = "s.png";
img2 = "k.png";
function chng(c_img) {
if (document[c_img].src.indexOf(img1)!= -1) document[c_img].src = img2;
else document[c_img].src = img1;
}
</script>
How can i write this html inside php code?
Thanks
<?php
// your php code
?>
<table>
<tr>
<img src="s.png" name="img">
</tr>
</table>
<?php
// your php code
?>
<script type="text/javascript">
img1 = "s.png";
img2 = "k.png";
function chng(c_img) {
if (document[c_img].src.indexOf(img1)!= -1) document[c_img].src = img2;
else document[c_img].src = img1;
}
</script>
<?php
you also could wrap your code in heredoc, and echo it afterwards http://www.php.net/manual/de/language.types.string.php#language.types.string.syntax.heredoc
you could echo the html; eg
echo "<table>
<tr>
<img src=\"s.png\" name=\"img\">
</tr>
</table>
";
Just escape the double quotes with a backslash.
You can use PHP heredoc syntax:
var $js = <<<JS
// code
JS;
Escapes and echo "<html_code>" is a noob style.
Use scriptlets and the command echo.
<?
echo "<script type=\"text\/javascript\">"
?>
and so far. But pay attention of masking quotations signs and backslashes, etc.
Write html tags inside php code isn't nice. Read about templates to php as Smarty
http://www.smarty.net/
<?php
$xml = simplexml_load_file('http://www.google.com/ig/api?weather=London');
$information = $xml->xpath("/xml_api_reply/weather/forecast_information");
$current = $xml->xpath("/xml_api_reply/weather/current_conditions");
$forecast_list = $xml->xpath("/xml_api_reply/weather/forecast_conditions");
?>

<span class="condition">
<?php echo round(conver_f_c($current[0]->temp_f['data'])); ?>° C,
<?php echo $current[0]->condition['data'] ?>

<?php foreach ($forecast_list as $forecast) : ?>

Update
From your latest comment so far:
i know how to fetch array and display
it, but i dont know to fetch and
display in the verticl manner that is
the stuck up
I feel this is going to be a stupid answer but it appears to be what you don't understand...
The web is based in a markup language called HTML. This language has tags (delimited by angle-brackets) that allow you to define the structure of a document. On top of this, you have another language called CSS. This other lang allow you to define how HTML is going to be displayed on screen.
You may argue that you already have a web page and you've written it with the PHP language instead of the two other langs I've mentioned. That's not enterely true: you code in PHP, sure, but you use PHP to generate HTML. And it's HTML what finally reaches the browser (Firefox, Explorer...). PHP is executed in the web server, not in the browser. The browser can only see whatever HTML you've generated.
To sum up: you have to forget about PHP, Google and the whole weather thingy. You first need to write a static HTML document and style it with CSS. Once you've done with it, you can finally replace the parts of the information that are dynamic with values taken from your PHP variables.
And since you seem to need a table to display tabular data, the appropriate HTML tag is <table>:
<table>
<tr>
<th>Web</th>
<th>Thu</th>
<th>Fri</th>
<th>Sat</th>
</tr>
<tr>
<td><img src="/path/to/pics/cloudy.png" width="25" height="25" alt="Cloudy"></td>
<td><img src="/path/to/pics/sunny.png" width="25" height="25" alt="Sunny"></td>
<td><img src="/path/to/pics/rainy.png" width="25" height="25" alt="Rainy"></td>
<td><img src="/path/to/pics/cloudy.png" width="25" height="25" alt="Cloudy"></td>
</tr>
<tr>
<td>26ºC</td>
<td>26ºC</td>
<td>22ºC</td>
<td>25ºC</td>
</tr>
<table>
I suggest you find some tutorials about basic HTML and CSS. They'll be of invaluable help.

Improve this question
When mixing PHP and HTML, what is the proper indentation style to use? Do I indent so that the outputted HTML has correct indentation, or so that the PHP/HTML mix looks properly formatted (and is thus easier to read)?
For example, say I have a foreach loop outputting table rows. Which one below is correct?
PHP/HTML mix looks correct:
<table>
<?php foreach ($rows as $row): ?>
<tr>
<?php if ($row->foo()): ?>
<?php echo $row ?>
<?php else: ?>
Something else
<?php endif ?>
</tr>
<?php endforeach ?>
</table>
Outputted HTML looks correct:
<table>
<?php foreach ($rows as $row): ?>
<tr>
<?php if ($row->foo()): ?>
<?php echo $row ?>
<?php else: ?>
Something else
<?php endif ?>
</tr>
<?php endforeach ?>
</table>
I've found that when I run into this situation (quite frequently), I don't have a standard style to use. I know that there may not be a "correct" answer, but I'd love to hear thoughts from other developers.
The PHP and the HTML should each be indented so that they are correct with respect to themselves in source form, irrespective of each other and of outputted form:
<table>
<?php foreach ($rows as $row): ?>
<tr>
<?php if ($row->foo()): ?>
<?php echo $row ?>
<?php else: ?>
Something else
<?php endif ?>
</tr>
<?php endforeach ?>
</table>
I often pondered this question too, but then I realized, who cares what the HTML output looks like? Your users shouldn't be looking at your HTML anyway. It's for YOU to read, and maybe a couple other developers. Keep the source code as clean as possible and forget about what the output looks like.
If you need to debug the output, use Chrome Developer Tools, Firebug, or even F12 Tools.
I generally put opening php tags at the beginning of the line, but indent whatever is inside the tags to match the html formatting. I don't do this, however, for simple echo statements since I use short-open tags. I think it makes simpler it when browsing through the file to find all the declarations.
<table>
<? foreach ($foo as $bar): ?>
<tr>
<? foreach ($bar as $baz): ?>
<td><?=$baz?></td>
<? endforeach ?>
</tr>
<? endforeach ?>
</table>
Direct answer to your question: If you need to read the HTML output often, it might be a good thing to output well indented HTML. But the more common case will be that you need to read your php source code, so it is more important that the source is easily readable.
Alternative to the two options you mentioned: See chaos' or tj111's answer.
Better still in my opinion: Don't mix HTML and php, use a template engine instead.
You can always use a bit of whitespace too to help readability. Building on chaos' indentation:
<table>
<?php foreach ($rows as $row): ?>
<tr>
<?php if ($row->foo()): ?>
<?php echo $row ?>
<?php else: ?>
Something else
<?php endif ?>
</tr>
<?php endforeach ?>
</table
The only downside with this is if you have a lot of mixed code it can make your document twice as long, which makes for more scrolling. Although if you have this much mixed code you may want to consider a templating engine.
You should not be bothered about markup indentation in the production environment. Neither should you use Tidy or other HTML purifiers. There are valid use cases, e.g. when you allow HTML input (but consider using Markdown instead), though these are rare.
Most often HTML beautifiers-filters are abused to hide the underlying issues with the code. Don't. Correct your markup manually.
If you need to indent your code only in the development environment, you can use either of the above. However, beware that these libraries will attempt to fix your markup (that's their primary purpose; indentation is a by-product). I've written Regular Expression based indentation tool Dindent.
Dindent will convert markup like this:
<!DOCTYPE html>
<html>
<head></head>

<script>
console.log('te> <st');
function () {
test; <!-- <a> -->
}
