I have a string, that look like this "<html>". Now what I want to do, is get all text between the "<" and the ">", and this should apply to any text, so that if i did "<hello>", or "<p>" that would also work. Then I want to replace this string with a string that contains the string between the tags.
For example
In:
<[STRING]>
Out:
<this is [STRING]>
Where [STRING] is the string between the tags.
Use a capture group to match everything after < that isn't >, and substitute that into the replacement string.
preg_replace('/<([^>]*)>/, '<this is $1>/, $string);
here is a solution to test on the pattern exists and then capture it to finally modify it ...
<?php
$str = '<[STRING]>';
$pattern = '#<(\[.*\])>#';
if(preg_match($pattern, $str, $matches)):
var_dump($matches);
$str = preg_replace($pattern, '<this is '.$matches[1].'>', $str);
endif;
echo $str;
?>
echo $str; You can test here: http://ideone.com/uVqV0u
I don't know if this can be usefull to you.
You can use a regular expression that is the best way. But you can also consider a little function that remove first < and last > char from your string.
This is my solution:
<?php
/*Vars to test*/
$var1="<HTML>";
$var2="<P>";
$var3="<ALL YOU WANT>";
/*function*/
function replace($string_tag) {
$newString="";
for ($i=1; $i<(strlen($string_tag)-1); $i++){
$newString.=$string_tag[$i];
}
return $newString;
}
/*Output*/
echo (replace($var1));
echo "\r\n";
echo (replace($var2));
echo "\r\n";
echo (replace($var3));
?>
Output give me:
HTML
P
ALL YOU WANT
