Take String Completely Literally in PHP

I generated an obfuscated email using the Hive Logic Enkoder. I want to echo the result in PHP.

The problem is that it contains ', ", \\ and \\\\, all of which mess up how PHP reads the string. How can I make PHP take this literally - escape the characters that need escaping, and un-escape the characters that don't?

So I want to:

echo '<script type="text/javascript">
    //<![CDATA[
    <!--
    var x="function f(x){var i,o=\"\",ol=x.length,l=ol;while(x.charCodeAt(l/13)!" +
    "=102){try{x+=x;l+=l;}catch(e){}}for(i=l-1;i>=0;i--){o+=x.charAt(i);}return " +
    "o.substr(0,ol);}f(\")12,\\\",&.=1,p?3k`,gcheB8'Xfo!l720\\\\430\\\\120\\\\>X" +
    "%E220\\\\230\\\\100\\\\530\\\\700\\\\RS,OT130\\\\630\\\\400\\\\230\\\\130\\" +
    "\\530\\\\4[120\\\\700\\\\600\\\\010\\\\300\\\\520\\\\,a038t=68&>&2?120\\\\(" +
    "*\\\"\\\\,v$>%!&+g030\\\\~$$2Wt\\\\I330\\\\400\\\\r\\\\JOGUImi3hu771\\\\tmt" +
    "yq\\\"(f};o nruter};))++y(^)i(tAedoCrahc.x(edoCrahCmorf.gnirtS=+o;721=%y;i=" +
    "+y)12==i(fi{)++i;l<i;0=i(rof;htgnel.x=l,\\\"\\\"=o,i rav{)y,x(f noitcnuf\")" ;
    while(x=eval(x));
    //-->
    //]]>
    </script>
';

Edit: here's the function I'm using now:

function supportEmail() {
    $str = <<<'EOT'
    <script type="text/javascript">
        //<![CDATA[
        <!--
        var x="function f(x){var i,o=\"\",ol=x.length,l=ol;while(x.charCodeAt(l/13)!" +
        "=102){try{x+=x;l+=l;}catch(e){}}for(i=l-1;i>=0;i--){o+=x.charAt(i);}return " +
        "o.substr(0,ol);}f(\")12,\\\",&.=1,p?3k`,gcheB8'Xfo!l720\\\\430\\\\120\\\\>X" +
        "%E220\\\\230\\\\100\\\\530\\\\700\\\\RS,OT130\\\\630\\\\400\\\\230\\\\130\\" +
        "\\530\\\\4[120\\\\700\\\\600\\\\010\\\\300\\\\520\\\\,a038t=68&>&2?120\\\\(" +
        "*\\\"\\\\,v$>%!&+g030\\\\~$$2Wt\\\\I330\\\\400\\\\r\\\\JOGUImi3hu771\\\\tmt" +
        "yq\\\"(f};o nruter};))++y(^)i(tAedoCrahc.x(edoCrahCmorf.gnirtS=+o;721=%y;i=" +
        "+y)12==i(fi{)++i;l<i;0=i(rof;htgnel.x=l,\\\"\\\"=o,i rav{)y,x(f noitcnuf\")" ;
        while(x=eval(x));
        //-->
        //]]>
        </script>
    EOT;
    echo $str;
}

But I get this error returned:

Parse error: syntax error, unexpected $end, expecting T_VARIABLE or T_END_HEREDOC or T_DOLLAR_OPEN_CURLY_BRACES or T_CURLY_OPEN

The reason it is giving this error is because there is white space before the closing EOT. Remove all tabs or white space in front or behind it.

You could store the string in a file/database, and from there obtain it from there.

The problem from using nowdocs/heredocs commented in the other answers is that \\ is an escaped slash in both of them.

You can also use a nowdoc block and replace all occurrence of \ to \\.

Try using Heredoc:

$str = <<<EOD
    <script type="text/javascript">
    //<![CDATA[
    <!--
    var x="function f(x){var i,o=\"\",ol=x.length,l=ol;while(x.charCodeAt(l/13)!" +
    "=102){try{x+=x;l+=l;}catch(e){}}for(i=l-1;i>=0;i--){o+=x.charAt(i);}return " +
    "o.substr(0,ol);}f(\")12,\\\",&.=1,p?3k`,gcheB8'Xfo!l720\\\\430\\\\120\\\\>X" +
    "%E220\\\\230\\\\100\\\\530\\\\700\\\\RS,OT130\\\\630\\\\400\\\\230\\\\130\\" +
    "\\530\\\\4[120\\\\700\\\\600\\\\010\\\\300\\\\520\\\\,a038t=68&>&2?120\\\\(" +
    "*\\\"\\\\,v$>%!&+g030\\\\~$$2Wt\\\\I330\\\\400\\\\r\\\\JOGUImi3hu771\\\\tmt" +
    "yq\\\"(f};o nruter};))++y(^)i(tAedoCrahc.x(edoCrahCmorf.gnirtS=+o;721=%y;i=" +
    "+y)12==i(fi{)++i;l<i;0=i(rof;htgnel.x=l,\\\"\\\"=o,i rav{)y,x(f noitcnuf\")" ;
    while(x=eval(x));
    //-->
    //]]>
    </script>
EOD;

EOT;

Wrap your string in <<<'EOT' EOT;
