I tried use file_put_contents output new page. but I meet some trouble in breaking new line.
<?php
$data ='<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">\r\n';
$data .='<html xmlns="http://www.w3.org/1999/xhtml" lang="en">\r\n';
$data .='<head>\r\n';
$data .='</head>\r\n';
$data .='<body>\r\n';
$data .='<p>put something here</p>\r\n';
$data .='</body>\r\n';
$data .='</html>\r\n';
file_put_contents( dirname(__FILE__) . '/new.php', $data);
?>
I tried \n or \r\n, they all can not make a new line:
1. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">\r\n<html xmlns="http://www.w3.org/1999/xhtml" lang="en">\r\n<head>\r\n</head>\r\n<body>\r\n<p>put something here</p>\r\n</body>\r\n</html>\r\n
Using \r or \n in single quotes carries it literally. use double quotes instead like "\r\n"
So one line might become:
$data .= "<head>\r\n";
or
$data .='<head>' . "\r\n";
You are using single-quoted character literals, which don't interpret escape sequences.
Either switch to double-quoted strings or, preferably, use heredoc syntax.
<?php
$data = <<<CONTENTS
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org /TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
<head>
</head>
<body>
<p>put something here</p>
</body>
</html>
CONTENTS;
file_put_contents( dirname(__FILE__) . '/new.php', $data);
?>
But really, why are you writing a hard-coded file? That's really strange.

I have issue to redirect another location after fopen() function in php. below is my function which i m using.
<?php
function create_file($filename){
$my_file = 'folder/index.php';
$fh = fopen($my_file, "wb");
$data = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Some data</title>
</head>
<body>Here some data</body>
</html>';
fwrite($fh, $data);
fclose($fh);
return true;
ob_end_clean();
exit();
}
$file = create_file(test);
if($file == true){
$url = 'http://example.com';
return $url;
}
else{
return 0;
}
?>
If you want to redirect in PHP, you cannot send any output to the server before header("Location: http://example.com");.
This includes any HTML, text or white spaces that aren't wrapped in a PHP tag set.
The header function must be called before any page output (if HTML has already been displayed, it's too late for your headers!).
When assigning numeric values (latitude and longitude values) to $_SESSION variables the values are stored correctly on the original script. However, when a 2nd page accesses the $_SESSION variables the value is now the name of the variable. See below.
page1.php code
<?
php session_start(); ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
var latitude = 35.0;
var longitude = -89.0;
<?php
$_SESSION['wailat'] = latitude;
$_SESSION['wailng'] = longitude;
?>
<p>Latitude is ' + <?php echo $_SESSION['wailat']; ?> <br>Longitude is <?php echo $_SESSION['wailng']; ?></p>
Page 2
</body>
</html>
Page 1 output is correct:
Latitude is 35.0
Longitude is -89.0
Page 2 code:
<?php session_start(); ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<?php
if (isset($_SESSION['wailat']) && isset($_SESSION['wailng']) ) {
echo 'Latitude ' . $_SESSION['wailat'] . '<br />Longitude ' . $_SESSION['wailng'];
} ?>
</body>
</html>
Page 2 output is incorrect:
Latitude is latitude
Longitude is longitude
Why do the two session variables' value on page 2 = the name of the variable that was assigned to them rather than the value?
Try this instead:
<?php
$latitude = 35;
$longitude = -89;
$_SESSION['wailat'] = $latitude;
$_SESSION['wailng'] = $longitude;
?>
You are writing the variables in html body , and it will display as it is on the page .this is not the way to declare variables. no variables are being created on the page. and even on the first page it will not echo the vars.
you must do it like #peter has mentioned.
I'm having a problem with file_get_contents and fwrite.
To get a script to work I have to print content from an external URL into a html file.
I'm using this code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<?php
$url = 'http://www.vasttrafik.se/nasta-tur-fullskarm/?externalid=9021014005135000';
$content = file_get_contents($url);
echo $content; // Actually writes out correct
$myFile = "response.php";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $content); // Doesn't write out correct ???
fclose($fh);
?>
</body>
</html>
When I echo out the file_get_contents, the HTML shows up nicely (with the Swedish special characters: åäö)
However.. The file "response.php" shows bad characters instead of åäö.
Any ideas? Does the fwrite use another encoding?
Thanks!
UPDATE!
Solved with this:
$content = "\xEF\xBB\xBF";
$content .= utf8_encode(file_get_contents($url));
SOLVED!
I needed to ad a BOM (Byte Order Mark) AND utf8_encode.
Like this:
$content = "\xEF\xBB\xBF";
$content .= utf8_encode(file_get_contents($url));
I have been racking my brains over this for hours, I need to pass some html to a function and have it replace the links and the return the html with the replaced links.
<?php
final static public function replace_links($campaign_id, $text) {
$regexp = "<a\s[^>]*href=(\"??)([^\" >]*?)\\1[^>]*>(.*)<\/a>";
if(preg_match_all("/$regexp/siU", $text, $matches, PREG_SET_ORDER)) {
foreach($matches as $match) {
if(substr($match[2], 0, 2) !== '##') { // ignore the placeholders
if(substr($match[2], 0, 6) !== 'mailto') { // ignore email addresses
// $match[2] = link address
// $match[3] = link text
$url = "http://xxx.com/click?campaign_id=$campaign_id&email=##email_address##&next=" . $match[2];
#$text .= str_replace($match[2], $url, $text);
#echo $links . "\n";
preg_replace($match[2], "<a href='$url'>{$match[3]}</a>", $match[2]);
}
}
return $text;
}
}
}
?>
When I echo the links it shows all the matched links. Question is how do i return the complete HTML with the replaced links example below.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
xxxx
xxxx
xxxx
</body>
</html>
Should become:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
xxxx
xxxx
xxxx
</body>
</html>
Hope this makes sense.
Thanks in advance,
Kyle
Don't reinvent the wheel just use something like this:
http://code.google.com/p/jquery-linkify/
It's really easy i use it as well
I don't know much about preg_replace, but i needed exatcly the same function as you.
Changing the line:
preg_replace($match[2], "<a href='$url'>{$match[3]}</a>", $match[2]);
for this:
str_replace($match[0],$url,$text);
seems to do the trick.
I just needed to get the return from this functions, so:
//$text = preg_replace($match[2], "<a href='$url'>{$match[3]}</a>", $match[2]);
$text = str_replace($match[0],$url,$text);
header('content-type: application/xml');
echo '<'.'?xml version="1.0"?'.'>';
echo '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">';
echo '<root>';
$hierarchy=$tree->getArray();
recursiveBuild($hierarchy[0]);
echo '</root>';
I am printing this as output to get XML... can i get these contents in a File.xml instead of file.php
Instead of seeing the xml in a php file, i need this to be outputted in direct XML.
You could buffer the output with the Output Buffering Control and write the buffered data into a file with file_put_contents:
ob_start();
echo '<'.'?xml version="1.0"?'.'>';
echo '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">';
echo '<root>';
$hierarchy=$tree->getArray();
recursiveBuild($hierarchy[0]);
echo '</root>';
file_put_contents('file.xml', ob_get_contents());
ob_end_clean();
