Simple: How to replace "all between" with php? [duplicate]
A generic function:
function replace_between($str, $needle_start, $needle_end, $replacement) { $pos = strpos($str, $needle_start); $start = $pos === false ? 0 : $pos + strlen($needle_start); $pos = strpos($str, $needle_end, $start); $end = $pos === false ? strlen($str) : $pos; return substr_replace($str, $replacement, $start, $end - $start);}
$search = "/[^<tag>](.*)[^<\/tag>]/";$replace = "your new inner text";$string = "<tag>i dont know what is here</tag>";echo preg_replace($search,$replace,$string);outputs:
<tag>your new inner text</tag>
$string = "<tag>I do not know what is here</tag>";$new_text = 'I know now'; echo preg_replace('#(<tag.*?>).*?(</tag>)#', '$1'.$new_text.'$2' , $string); //<tag>I know now</tag>
