帮我写一些字符串到“php语法”

Question

I am having some trouble on writing some strings I want to use in PHP syntax with preg_match_all.

All I managed to do correctly is to write <span style=""> to $regex_pattern = "/\<span style=\"color: red;\"\>(.*?)\<\/span\>/i"; but can't do any further than that.

I mean I cant write correctly <h3 class=''> or get the link between <h3 class=""><a href=" and </a>. Please help me with the above and give me some examples if you want or any online tools for this.

Thanks in advance!

Answer 1

echo "<span style='color:red;'>Text</span>";

Best way is to:

if(condition){

?>

<!-- HTML here -->

<?

}

else

  linefeed (LF or 0x0A (10) in ASCII)
  carriage return (CR or 0x0D (13) in ASCII)
\t  horizontal tab (HT or 0x09 (9) in ASCII)
\\  backslash
\$  dollar sign
\"  double-quote
\[0-7]{1,3}     the sequence of characters matching the regular expression is a character in octal notation
\x[0-9A-Fa-f]{1,2}  the sequence of characters matching the regular expression is a character in hexadecimal notation
