Good day.
We have code:
function testfunc($text){
return $text;
}
$text = "Simple text {testfunc(1)} and next simple text and we {testfunc(20)} are happy ";
// number in {testfunc()} only for example - it can be other number or text.
Tell me please how replace {testfunc(1)} on result function testfunc($num)?
P.S.: In result need get next text:
$text = "Simple text 1 and next simple text and we 20 are happy ";
Try this:
$newText = preg_replace_callback("/\{testfunc\((\d+)\)\}/","testfunc",$text);
And you'll get array of matches in your "testfunc". For what you want, this code:
I think, it helps you.
<?php
function testfunc($text){
return $text[1];
}
$text = "Simple text {testfunc(1)} and next simple text and we {testfunc(20)} are happy ";
$newText = preg_replace_callback("/\{testfunc\((\d+)\)\}/","testfunc",$text);
echo $text."\n";
echo $newText."\n";
?>
This should work, using string concatenation:
$text = "Simple text " . testfunc(1) . " and next simple text and we " . testfunc(20) . " are happy ";
Try
$text = "Simple text ".testfunc(1)." and next simple text and we ".testfunc(20)." are happy ";
As normal why not try with,
$text = "Simple text ".testfunc(1)." and next simple text and we ".testfunc(20)." are happy ";
<?php
$text = "Simple text ".testfunc(1)." and next simple text and we ".testfunc(20)." are
happy";
echo $text;
?>

I have a data base with texts and in each text there are words (tags) that start with # (example of a record : "Hi I'm posting an #issue on #Stackoverflow ")
I'm trying to find a solution to add html code to transform each tag into a link when printing the text.
So the text are stored as strings in MySQL database like this :
Some text #tag1 text #tag2 ...
I want to replace all these #abcd with
#abcd
And have a final result as follow:
Some text #tag1 text #tag2 ...
I guess that i should use some regex but it is not at all my strong side.
Try the following using preg_replace(..)
$input = "Hi I'm posting an #issue on #Stackoverflow";
echo preg_replace("/#([a-zA-Z0-9]+)/", "<a href='targetpage.php?val=$1'>#$1</a>", $input);
http://php.net/manual/en/function.preg-replace.php
A simple solution could look like this:
$re = '/\S*#(\[[^\]]+\]|\S+)/m';
$str = 'Some text #tag1 text #tag2 ...';
$subst = '#$1';
$result = preg_replace($re, $subst, $str);
echo "The result of the substitution is ".$result;

If you are actually after Twitter hashtags and want to go crazy take a look here how it is done in Java.
There is also a JavaScript Twitter library that makes things very easy.
Try this the function
<?php
$demoString1 = "THIS is #test STRING WITH #abcd";
$demoString2 = "Hi I'm posting an #issue on #Stackoverflow";
function wrapWithAnchor($link,$string){
$pattern = "/#([a-zA-Z0-9]+)/";
$replace_with = '<a href="'.$link.'?val=$1">$1<a>';
return preg_replace( $pattern, $replace_with ,$string );
}
$link= 'http://www.targetpage.php';
echo wrapWithAnchor($link,$demoString1);
echo '<hr />';
echo wrapWithAnchor($link,$demoString2);
?>
I had an value in database like "demo text" . I want to display this content from the db in the view page as
Html code that i am using is like this <h2>Demo<span>Text</span></h2> , is there any solution for seperate each words and use one for h2 and other for span. I am using php codeigniter for the project , I don't know that whether the way i explained my problem is correct or not .
Yes you can so it with explode
if you have stored at least 2 words with space. try following
$demo ="demo text";
$arr = explode(" ",$demo);
$str = "<h2>".$arr[0]."<span>".$arr[1]."</span></h2>";
echo $str;
DEMO
EDIT
If you have more words and want to split first word only you can pass limit parameter in explode
$demo ="Pligrimage to Marian Shrines";
$arr = explode(" ",$demo,2);
$str = "<h2>".$arr[0]."<span>".$arr[1]."</span></h2>";
echo $str;
DEMO
I think you are looking for something like this!
$your_string = "Hello Houston! We have a problem!";
$my_array = explode(" ",trim($your_string));
$output = "<h2>";
foreach($my_array as $a_word){
if ($a_word === reset($my_array))
$output .= $a_word;
else
$output .= " <span>". $a_word . "</span>";
}
$output .= "</h2>";
print $output;
I'm getting a text in a variable as follows:
$text = 'This is a code snippet';
Now I want to enclose the above text within [cdata]...[!cdata].
The output of echo $text should be like below:
[cdata]This is a code snippet[!cdata]
How should I do this?
Thanks.
Try
$text = 'This is a code snippet';
$text = '[cdata]'.$text.'[!cdata]';
echo $text;
Try this
$text = "This is a code snippet";
$text = "[cdata]{$text}[!cdata]";
echo $text;
i have been dealing with this for awhile and i could not figure out how to do the following in PHP:
$string = "this is test <pre>somrthing in <p>pharagraph</p></pre> dont know tell me <pre>value33 kooo ok</pre> this is php regress <pre>teeth value</pre> ok how";
function get_innercode($string) {
preg_match_all("#<pre>(.*?)</pre>#", $string, $foo);
echo implode("\n", $foo[1]);
}
$insert1=get_innercode($string);
$insert2=" 2 place me in the pre tag"; // you can ignore this
$string="this is test <pre> WHERE $insert1 SHOULD BE</pre> dont know tell me <pre>WHERE $insert2 SHOULD BE</pre> ok how ";
how can i do this?
Please note i cannot do
$string="some text here <pre> WHERE $insert1 SHOULD BE</pre> some more text here <pre>WHERE $insert2 SHOULD BE</pre> ok how";
because i am getting $insert1 and $insert2 from $string to modify. i need to place it back in there where they come from.
thank you
It's pretty easy to do:
$insert1 =" 1 place me in the pre tag";
$insert2 =" 2 place me in the pre tag";
$string = "some text here <pre>{$insert1}</pre> some more text here <pre>{$insert2}</pre> and may be some more text or ";
You can echo a variable from inside a string when it's wrapped around double quotes. This does not work with single quotes.
Edit: This might be what you are looking for then:
$string = "This my <code>awesome</code> code";
$string = preg_replace('/<code>(.*?)<\/code>/', '<pre>$1</pre>', $string);
In php you can concatenate strings with a "." before and after, example:
$var1 = "hello";
$var2 = "What's up";
$concat = "Hey, ".$var1." ,".$var2."<br>";
echo $concat;
Similar methodology here. This allows for larger areas to be filled
$insert[0] = "Some Text";
$insert[1] = "Some More Text";
function Parser($content){
$i = 0;
while (preg_match_all('`\<pre\>(.*?)\</pre\>`', $content, $matches)) {
foreach ($matches[0] as $key => $match) {
//$innertext = $matches[1][$key]; //replace with your preferred filler
$innertext = $insert[$i]; //such as this
$replacement = '<pre>' . trim($innertext) . '</pre>';
$content = str_replace($match, $replacement, $content);
$i++;
}
}
}
Parse your line(s) of content like so:
Parser("this is test <pre> WHERE $insert1 SHOULD BE</pre> dont know tell me <pre>WHERE $insert2 SHOULD BE</pre> ok how");
This is untested so may have a couple of bugs in it.
Try this,
I am adding div tag before each pre content. You can also modify content as needed by using $matches[1]
$string_new = preg_replace_callback(
'#<pre>(.*?)</pre>#',
function ($matches) {
return "<div>".$matches[0]."</div>";
},
$string
);
echo $string_new;
I have some text like the following example:
Some Text Here
[code]Some link[/code]
Text
[code]Link[/code]
Other Text
[code]Another Link[/code]
Other Text1
I want to remove all the text above, under, and between the two code. Here's an example of the output I want:
[code]Some Link[/code]
[code]Link[/code]
[code]Another Link[/code]
I use preg_replace for removing text above the first Code, in this way:
$message = preg_replace('/(.*?)\[code/si','[code',$message, 1);
Can you help me to remove the other text, using preg_replace?
You can do this way:
preg_match_all('/(\[code\].*\[\/code\])/Usmi', $text, $res);
$cnt = 0;
foreach ($res as $val) {
$cnt++;
$message .= $val[$cnt] . "<br />";
}
echo $message;
Just to make the solution of #Andreev a little more simple :
$text = "
Some Text Here
[code]Some link[/code]
Text
[code]Link[/code]
Other Text
[code]Another Link[/code]
Other Text1
";
$keywords = preg_match_all('/(\[code\].*\[\/code\])/Usmi', $text, $res);
print(implode($res[0]));
You can test it here : http://phptester.net/index.php?lang=en
Assuming you can never have [code] abc [code] def [/code] ghi [/code], try this:
do {
$message = preg_replace("((?:\[code\].*?\[/code\])*).*?(?=\[code\]))is","$1",$message,-1,$c);
} while($c);
