Invalid UTF-8 codepoint escape¶
Description¶
PHP supports unicode as escape sequence. They are used in double-quoted strings, and use the \u{73}
format. The digits must represent a valid unicode codepoint: here, 73 represents the ASCII letter s
.
When the prefix \u{
is detected, PHP tries to understand the next characters as an integer. When this is not the case, it fails the codepoint detection and stops.
Example¶
<?php
$a = "\u{fgh}";
?>
Solutions¶
Check the values inside the curly braces: chances are it needs to be replaced with smaller values.
If there is no intent to use unicode codepoint, add
\
to make PHP handle it as a literal value.
