Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.";$str = wordwrap($str,30,'\n');?>document.write('test' + '\n');document.write( '<?php echo $str;?>' + '\n' );</script>控制台错误：Uncaught SyntaxError: missing ) after argument list。哪里有问题？

正如@u_mulder 指出的那样，您必须将引号转义'为：

<?php

    $str = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.";

    $str = str_replace("'", "\'", wordwrap($str,30,'\n'));

?>

<script>

    document.write('test' + '\n');

    document.write( '<?php echo $str;?>' + '\n' );

</script>
