I recently heard about a function called token_get_all and I want to find out how to get all of the T_INLINE_HTML out of a php file containing PHP code and HTML. For example, a file like this:
<?php
echo "This is my PHP code";
?>
<html>
<p>Hello, this is the HTML code I want from token_get_all!</p>
</html>
I was attempting to use:
$tokens = token_get_all($filecontents);
$html = $tokens(T_INLINE_HTML);
but that didn't work. How might I do this?
The following code will filter out the tokens of a file which and leave you with only inline HTML ones:
$tokens = token_get_all($filecontents);
$tokens = array_filter($tokens, function($token)
{
return $token[0] == T_INLINE_HTML;
});

I've searched around and around and I'm not sure how this really works.
I have the tags
<taghere>content</taghere>
and i want to pull the "content" so i can put an ifstatement depending on what the "content" is as the "content" is varrying depending on the page
i.e
<taghere>HelloWorld</taghere>
$content = //function that returns the text between <taghere> and </taghere>
if($content == "HelloWorld")
{
//execute function;
}
else if($content =="Bonjour")
{
//execute seperate function
}
i tried using preg but it doesnt seem to work and just returns whatever value is in the lines field instead of actually giving me the information within the tags
If I understand your question correctly, you want the data INSIDE the tag "taghere".
If you are parsing HTML, you should use DOMDocument
Try something similar to this:
<?php
// Assuming your content (the html where those tags are found) is available as $html
$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($html); // loads your HTML
libxml_clear_errors();
// Note: Tag names are case sensitive
$text = $dom->getElementsByTagName('taghere');
// Echo the content
echo $text
you can use DomDocument and loadXML to do this
<?php
function doAction($word=""){
$html="<taghere>$word</taghere>";
$doc = new DOMDocument();
$doc->loadXML($html);
//discard white space
$hTwo= $doc->getElementsByTagName('taghere'); // here u use your desired tag
if($hTwo->item(0)->nodeValue== "HelloWorld")
{
echo "1";
}
else if($hTwo->item(0)->nodeValue== "Bonjour")
{
echo "2";
//execute seperate function
}
}
doAction($word="Bonjour");
You cannot do it like that. Technically it is possible but it's more than an overkill. And you mixed up PHP with HTML in a way that doesn't work.
To achieve the thing that you want you have to do something like this:
$content = 'something';
if ($comtent === 'something') {
//do something
}
if ($content === 'something else') {
//do something else
}
echo '<tag>'. $content . '</tag>' ;
Of course you can change $content in the ifs.
Dont forget, you can allways add an ID into a tag so you can reference it with java script.
<tag id='tagid'>blah blah blah </tag>
<script>
document.getElementById(tagid)
</script>
This might be a much simpler way to get what you are thinking about then some of the other responses
I don't know what regex you tried and therefor not what would have been wrong. Might have been the escaping of the <
<?php
if(preg_match('#\<taghere>(.*)\</taghere>#', $document, $a)){
$content = $a[1];
}
?>
I suppose there will be only one
This block of PHP code prints out some information from a file in the directory, but I want the information printed out by echo to be used inside the HTML below it. Any help how to do this? Am I even asking this question right? Thanks.
if(array_pop($words) == "fulltrajectory.xyz") {
$DIR = explode("/",htmlspecialchars($_GET["name"]));
$truncatedDIR = array_pop($DIR);
$truncatedDIR2 = ''.implode("/",$DIR);
$conffile = fopen("/var/www/scmods/fileviewer/".$truncatedDIR2."/conf.txt",'r');
$line = trim(fgets($conffile));
while(!feof($conffile)) {
$words = preg_split('/\s+/',$line);
if(strcmp($words[0],"FROZENATOMS") == 0) {
print_r($words);
$frozen = implode(",", array_slice(preg_split('/\s+/',$line), 1));
}
$line = trim(fgets($conffile));
}
echo $frozen . "<br>";
}
?>
The above code prints out some information using an echo. The information printed out in that echo I want in the HTML code below where it has $PRINTHERE. How do I get it to do that? Thanks.
$("#btns").html(Jmol.jmolButton(jmolApplet0, "select atomno=[$PRINTHERE]; halos on;", "frozen on")
You just need to make sure that your file is a php file..
Then you can use html tags with php scripts, no need to add it using JS.
It's as simple as this:
<div>
<?php echo $PRINTHERE; ?>
</div>
Do remember that PHP is server-side and JS is client-side. But if you really want to do that, you can pass a php variable like this:
<script>
var print = <?php echo $PRINTHERE; ?>;
$("#btns").html(Jmol.jmolButton(jmolApplet0, "select atomno="+print+"; halos on;", "frozen on"));
</script>
I am working on a script with templates. So I have this PHP code:
<?php
$string = "TEST";
echo(file_get_contents('themes/default/test.html'));
?>
And I have this HTML (the test.html file):
<html>
<p>{$string}</p>
</html>
How can I make PHP actually display the variable inside the curly brackets? At the moment it displays {$string}.
P.S:
The string might also be an object with many many variables, and I will display them like that: {$object->variable}.
P.S 2: The HTML must stay as it is. This works:
$string = "I'm working!"
echo("The string is {$string}");
I need to use the same principle to display the value.
You can use the following code to achieve the desired result:
<?php
$string = "TEST";
$doc = file_get_contents('themes/default/test.html'));
echo preg_replace('/\{([A-Z]+)\}/', "$$1", $doc);
?>
P.S. Please note that it will assume that every string wrapped in { }
has a variable defined. So No error checking is implemented in the code above. furthermore it assumes that all variables have only alpha characters.
If it is possible to save your replacees in an array instead of normal variables you could use code below. I'm using it with a similar use case.
function loadFile($path) {
$vars = array();
$vars['string'] = "value";
$patterns = array_map("maskPattern", array_keys($vars));
$result = str_replace($patterns, $vars, file_get_contents($path));
return $result;
}
function maskPattern($value) {
return "{$" . $value . "}";
}
All you PHP must be in a <?php ?> block like this:
<html>
<p><?php echo "{" . $string . "}";?></p>
</html>
If you know the variable to replace in the html you can use the PHP function 'str_replace'. For your script,
$string = "TEST";
$content = file_get_contents('test.html');
$content = str_replace('{$string}', $string, $content);
echo($content);
It's simple to use echo.
<html>
<p>{<?php echo $string;?>}</p>
</html>
UPDATE 1:
After reading so many comments, found a solution, try this:
$string = "TEST";
$template = file_get_contents('themes/default/test.html', FILE_USE_INCLUDE_PATH);
$page = str_replace('{$string}',$string,$template);
echo $page;
I wanna replace braces with <?php ?> in a file with php extension.
I have a class as a library and in this class I have three function like these:
function replace_left_delimeter($buffer)
{
return($this->replace_right_delimeter(str_replace("{", "<?php echo $", $buffer)));
}
function replace_right_delimeter($buffer)
{
return(str_replace("}", "; ?> ", $buffer));
}
function parser($view,$data)
{
ob_start(array($this,"replace_left_delimeter"));
include APP_DIR.DS.'view'.DS.$view.'.php';
ob_end_flush();
}
and I have a view file with php extension like this:
{tmp} tmpstr
in output I save just tmpstr and in source code in browser I get
<?php echo $tmp; ?>
tmpstr
In include file <? shown as <!--? and be comment. Why?
What you're trying to do here won't work. The replacements carried out by the output buffering callback occur after PHP code has already been parsed and executed. Introducing new PHP code tags at this stage won't cause them to be executed.
You will need to instead preprocess the PHP source file before evaluating it, e.g.
$tp = file_get_contents(APP_DIR.DS.'view'.DS.$view.'.php');
$tp = str_replace("{", "<?php echo \$", $tp);
$tp = str_replace("}", "; ?>", $tp);
eval($tp);
However, I'd strongly recommend using an existing template engine; this approach will be inefficient and limited. You might want to give Twig a shot, for instance.
do this:
function parser($view,$data)
{
$data=array("data"=>$data);
$template=file_get_contents(APP_DIR.DS.'view'.DS.$view.'.php');
$replace = array();
foreach ($data as $key => $value) {
#if $data is array...
$replace = array_merge(
$replace,array("{".$key."}"=>$value)
);
}
$template=strtr($template,$replace);
echo $template;
}
and ignore other two functions.
How does this work:
process.php:
<?php
$contents = file_get_contents('php://stdin');
$contents = preg_replace('/\{([a-zA-Z_][a-zA-Z_0-9]*)\}/', '<?php echo $\1; ?>', $contents);
echo $contents;
bash script:
process.php < my_file.php
Note that the above works by doing a one-off search and replace. You can easily modify the script if you want to do this on the fly.
Note also, that modifying PHP code from within PHP code is a bad idea. Self-modifying code can lead to hard-to-find bugs, and is often associated with malicious software. If you explain what you are trying to achieve - your purpose - you might get a better response.
I'm trying to get php code out of a HTML template file to execute it and place the result back.
What regular expression code can I use? And is there a method that also return the position of the found first tag?
<p>some html</p>
<?php $some = "php code"; ?>
<p>some <em>more</em> html</p>
<?php $some = "more php code"; ?>
I want the php code filtered from the html.
preg_match("/<\?.*?\?>/m",$output,$matches)
or
preg_match("/<\?.*?\?>/s",$output,$matches)
Should match all lines.
Instead of "getting the PHP out and putting it back" you should pass the variables to the template file.
Something like this:
<?php
function loadTemplate($path,$data=array()){
if (file_exists($path) === false){
throw new Exception('Template not found:'.$path);
return false;
}
extract($data);
ob_start();
require($path);
$return = ob_get_contents();
ob_end_clean();
return $return;
}
$vars = array('var1'=>$value,
'var2'=>$somevalue,
'var3'=>$someothervalue,
'var4'=>$blab);
$template = loadTemplate('path/to/thefile.php',$vars);
?>
Then access the $vars array values from within thefile.php like
echo $var1
echo $var2
ect
Hope it helps
