Run javascript using echo in php

Question

I have this code of javascript

echo '<script type="text/javascript">';
echo 'document.write('<a style="display:block;width:100%;height:1px;" class="aff-ad-none"></a>');
window.AFF_ONLOAD = window.AFF_ONLOAD || [];window.AFF_ONLOAD.push({lkid:"11",affid:"10",size:"728*90",type:"1",language:"English",web_id:"40",version:110});
var aff_s = document.createElement("script"),aff_h = document.getElementsByTagName("head")[0];aff_s.charset = "utf-8";aff_s.async = !0;aff_s.src = "https://js.affasi.com/affasi_js.min.js";
aff_h.insertBefore(aff_s, aff_h.firstChild);
</script>';

I get Parse error: parse error, expecting ','' or';'' The error is in this line : echo 'document.write('<a style="display:block;width:100%;height:1px;" class="aff-ad-none"></a>'); ....

How do i add single quote in echo command? This should fix the error i guess right?

Answer 1

You need to escape the parentheses ' with \ in document.write() like this:

<?php
echo '<script type="text/javascript">';
echo 'document.write(\'<a style="display:block;width:100%;height:1px;" class="aff-ad-none"></a>\');
window.AFF_ONLOAD = window.AFF_ONLOAD || [];
window.AFF_ONLOAD.push({lkid:"11",affid:"10",size:"728*90", type:"1",language:"English",web_id:"40",version:110});
var aff_s = document.createElement("script"),aff_h = 
document.getElementsByTagName("head")[0];aff_s.charset = "utf-8";aff_s.async = 
!0;aff_s.src = "https://js.affasi.com/affasi_js.min.js";
aff_h.insertBefore(aff_s, aff_h.firstChild);
</script>';
?>

• stefanosn: Thanks for your answer as well. It seems that i get the correct output and i have no error but the content of the javascript does not show up in the webpage! Weird!

Answer 2

• you you need to escape charcter (the best way)

echo 'document.write(\'<astyle="display:block;width:100%;height:1px;" class="aff-ad-none"></a>\'); '

• you can put the string in a variable like $var ='<a style="display:block;width:100%;height:1px;" class="aff-ad-none"></a>' ; echo 'document.write('.$var.');'

• the third way is to cut string into 3 segmant and concat them echo 'document.write('.'<a style="display:block; width: 100%" ></a>'.');'

Answer 3

You need to use double quote inside your single quote.

echo '<script type="text/javascript">';
echo 'document.write("<a style="display:block;width:100%;height:1px;" class="aff-ad-none"></a>");
window.AFF_ONLOAD = window.AFF_ONLOAD || [];window.AFF_ONLOAD.push({lkid:"11",affid:"10",size:"728*90",type:"1",language:"English",web_id:"40",version:110});
var aff_s = document.createElement("script"),aff_h = 
document.getElementsByTagName("head")[0];aff_s.charset = "utf-8";aff_s.async = !0;aff_s.src = "https://js.affasi.com/affasi_js.min.js";
aff_h.insertBefore(aff_s, aff_h.firstChild);
</script>';

You can also escape your single quote using a \ like so : \'

• stefanosn: Thanks for your answer i got the output like this: <script type="text/javascript">document.write('<a style="display:block;width:100%;height:1px;" class="aff-ad-none"></a>'); window.AFF_ONLOAD = window.AFF_ONLOAD || [];window.AFF_ONLOAD.push({lkid:"11599254",affid:"10054952",size:"728*90",type:"1",language:"English",web_id:"40",version:110}); var aff_s = document.createElement("script"),aff_h = document.getElementsByTagName("head")[0];aff_s.charset = "utf-8";aff_s.async = !0;aff_s.src = "js.affasi.com/affasi_js.min.js"; aff_h.insertBefore(aff_s, aff_h.firstChild); </script> with \'
• stefanosn: But cant see the output in the webpage for some reason! That is weird!
• Nicolas: Well i can't help you with your Javascript. i don't have any context.
• stefanosn: It was probably the content offline. I added a new one and it works thanks for your help!

Answer 4

You can use EOT :

$string = <<<EOT
<script type="text/javascript">
document.write('<a style="display:block;width:100%;height:1px;" class="aff-
ad-none"></a>');
window.AFF_ONLOAD = window.AFF_ONLOAD || [];
window.AFF_ONLOAD.push({lkid:"11",affid:"10",size:"728*90", type:"1",language:"English",web_id:"40",version:110});
var aff_s = document.createElement("script"),aff_h = 
document.getElementsByTagName("head")[0];aff_s.charset = "utf-8";aff_s.async = 
!0;aff_s.src = "https://js.affasi.com/affasi_js.min.js";
aff_h.insertBefore(aff_s, aff_h.firstChild);
</script>
EOT;
echo $string;

Answer 5

Try the following.

<script type="text/javascript">document.write('<a style="display:block;width:100%;height:1px;" class="aff-ad-none"></a>');window.AFF_ONLOAD = window.AFF_ONLOAD || [];window.AFF_ONLOAD.push({lkid:"13172240",affid:"10068701",size:"300*250",type:"1",language:"en",web_id:"40",version:110});var aff_s = document.createElement("script"),aff_h = document.getElementsByTagName("head")[0];aff_s.charset = "utf-8";aff_s.async = !0;aff_s.src = "https://js.affasi.com/affasi_js.min.js";aff_h.insertBefore(aff_s, aff_h.firstChild);</script>

• AuxTaco: This doesn't answer the question. It also changes the values of lkid and affid, which seems... suspicious.
