I want to fetech all @media tags from css file using php

CodePudding user response：

With the function preg_match_all you could determine the lines and the contents starting with @media

preg_match_all("/(@media .*)/", $cssContent, $matches);

Example Output:

array(2) {
  [0]=>
  array(2) {
    [0]=>
    string(79) "@media screen and (max-width: 425px) {.style_outerContainer {padding: 20px 0 0}"
    [1]=>
    string(122) "@media screen and (min-width: 768px) {.style_out .style_c {bottom: 0;height: auto;position: relative;top: 0;width: 100%} }"
  }
  [1]=>
  array(2) {
    [0]=>
    string(79) "@media screen and (max-width: 425px) {.style_outerContainer {padding: 20px 0 0}"
    [1]=>
    string(122) "@media screen and (min-width: 768px) {.style_out .style_c {bottom: 0;height: auto;position: relative;top: 0;width: 100%} }"
  }
}

Second solution:

$matches = [];
$lines = explode("\n", $cssContent); // lines from css
foreach ($lines as $line) {
    if (strpos($line, "@media") !== false) { // check each line 
        $matches[] = $line;
    }
}
