Available Functions

The following functions are available:

+
+
+xml_convert($str[, $protect_all = FALSE])
+
+++ + + + + + + + +
Parameters:
    +
  • $str (string) – the text string to convert
    • +
  • $protect_all (bool) – Whether to protect all content that looks like a potential entity instead of just numbered entities, e.g. &foo;
    • +
+
Returns:

XML-converted string

+
Return type:

string

+
+

Takes a string as input and converts the following reserved XML +characters to entities:

+
+
    +
  • Ampersands: &
    • +
  • Less than and greater than characters: < >
    • +
  • Single and double quotes: ‘ “
    • +
  • Dashes: -

+

This function ignores ampersands if they are part of existing numbered +character entities, e.g. &#123;. Example:

+
$string = '<p>Here is a paragraph & an entity (&#123;).</p>';
+$string = xml_convert($string);
+echo $string;
+
+
+

outputs:

+
&lt;p&gt;Here is a paragraph &amp; an entity (&#123;).&lt;/p&gt;
