I can't figure out how to use PHP variables
if( $xml = file_get_contents( $user '/docs.xml') ) {
It says unexpected ''/docs.xml'' (T_CONSTANT_ENCAPSED_STRING)
I've researched and can't find anything on adding variables to get_file_contents
Please Help
You need to combine the variable and the string literal via concatenation (Wikipedia):
if( $xml = file_get_contents( $user . '/docs.xml') ) {
Also, if you use double quoted strings, you can place the variable inside of the string and have its value expanded:
if( $xml = file_get_contents("$user/docs.xml") ) {
if ($xml = file_get_contents( $user . '/docs.xml') ) {
}
Looks like you are trying to concatenate, or combine the $user variable with the literal string '/docs.xml'.
In PHP you combine strings with the period . operator.
$string = "Testing" . " to see" . " if this really works";
echo $string;
// Outputs: Testing to see if this really works.
echo statement, which can take multiple arguments separated with commas.
There are many ways to concatenate strings in PHP. You should try this.
if( $xml = file_get_contents( $user . "/docs.xml") ) {
Read more on the documentation.
Probably quoting issue, so try this:
if( $xml = file_get_contents("$user/docs.xml") ) {
