How can I use <code>preg_match</code> to see if special characters <code>[^'£$%^&*()}{@:'#~?><>,;@|\-=-_+-¬`]</code> exist in a string?

<code>[\W]+</code> will match any non-word character. but to match only the characters from the question, use this: <pre class="prettyprint"><code> $string="sadw$" if(preg_match("/[\[^\'£$%^&*()}{@:\'#~?><>,;@\|\\\-=\-_+\-¬\`\]]/", $string)){ //this string contain atleast one of these [^'£$%^&*()}{@:'#~?><>,;@|\-=-_+-¬`] characters } </code></pre>
