PHP string cut short – Education Career Blog

Why does this code

$string = "[email protected]#$%^&*(<[email protected]"; 
echo $string; 

only output:

[email protected]#$%^&*(

Is this is a PHP bug?


Because < is a reserved character in in HTML 🙂

Use &lt; and &gt;

You can use the function htmlspecialchars to convert such special chars


I’m not seeing that:

Perhaps you’ve got some weird characters in your file? Make sure you’re using a “normal” encoding on your source code, as well.


You need to do:

echo htmlentities($string);

to display the string as it is on a browser. This is because the < in the string is interpreted by the browser as start of a HTML tag.

So it’s not PHP but the browser that is causing this behavior. If you do the exact same display on a command line, you’ll see all the characters.


If you are viewing the output in a web browser, then the < begins a tag and is usually not displayed but interpreted in the HTML document structure parser. Also, a $ inside of a double-quoted string is interpolated as the variable name that follows it; try using single quotes where this won’t happen.

Try this:

$string = '[email protected]#$%^&*(<[email protected]';
echo htmlentities($string);
