Parsing an echo in PHP

Question

I have what is, for me, quite a complex line I want to parse into php.

echo '<input class="cbox" onclick="if(this.checked){document.getElementById('school').style.display ='inline'}else{document.getElementById('school').style.display ='none'}" type="checkbox" name="type[]" value="School" checked/><br>';

Obviously, if I use speech marks to enclose the echo, it would fall apart in the onlick event. How can I avoid this?

Answer 1

要在php中转义字符，请使用\\，如下所示：

echo '<input class="cbox" onclick="if(this.checked){document.getElementById(\'school\').style.display =\'inline\'}else{document.getElementById(\'school\').style.display =\'none\'}" type="checkbox" name="type[]" value="School" checked/><br>';

Answer 2

You need to escape your quotes with \\"

Like this:

echo "<input class=\"cbox\" onclick=\"if(this.checked){document.getElementById('school').style.display ='inline'}else{document.getElementById('school').style.display ='none'}\" type=\"checkbox\" name=\"type[]\" value=\"School\" checked/><br>";

Answer 3

在'之前添加斜杠。

echo '<input class="cbox" onclick="if(this.checked){document.getElementById(\'school\').style.display =\'inline\'}else{document.getElementById(\'school\').style.display =\'none\'}" type="checkbox" name="type[]" value="School" checked/><br>';

Answer 4

If you use double-quotes, you can escape any other double-quotes by putting the \\ character before them.

There are some more details at: http://php.net/manual/en/language.types.string.php

Answer 5

NEVER use echo to output HTML.
But always type it as is

?>
<input class="cbox" 
 onclick="if(this.checked){
    document.getElementById('school').style.display='inline'
}else{
     document.getElementById('school').style.display ='none'}" 
type="checkbox" name="type[]" value="School" checked/><br>
