PHP wordwrap 数组到 Javascript 返回错误

Question

运行以下代码时出现控制台错误：

<?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.";

$str = wordwrap($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>
