Function analysis to remove PHP comment spaces from PHP files (PHP code compression)_PHP tutorial

Recently, I learned from thinkphp's 'RUNTIME_ALLINONE' experience: I am not afraid of too many caches, but I am afraid of chaotic calls. Wouldn't it be nice to simply merge all commonly used files into one file? . .

Copy code The code is as follows:

function strip_whitespace($content) {
$stripStr = '';
//Analyze php source code
$tokens = token_get_all ($content);
$last_space = false;
for ($i = 0, $j = count ($tokens); $i if (is_string ($tokens[$i])){
$last_space = false;
$stripStr .= $tokens[$i];
}
else{
switch ($tokens[$i][0]){
//Filter various PHP comments
case T_COMMENT:
case T_DOC_ COMMENT:
break;
/ /Filter spaces
case T_WHITESPACE:
if (!$last_space){
$stripStr .= ' ';
                                                                                     :
                      $last_space = false;                                                         🎜> return $stripStr;
}


This custom function effectively solves the problem that the built-in comment space function of the php_strip_whitespace system cannot correctly understand
How to use it

Copy code

The code is as follows:
$str = strip_whitespace('You must splice this before. I don’t understand it. If you don’t splice it, the generated result will be wrong.php_strip_whitespacestring php_strip_whitespace (string$filename)

If it is just a single file and there is no heredoc, it is recommended to use the quick
php_strip_whitespace
