Subject: Expand variable in comparison
Hi!
Is there any way to get the following snippet returning a true?
...
$this->var = ?????
if ($this->var == $preDefinedStringToTestWith)
return true;
else
false;
The problem:
I don't know, what $preDefinedStringToTestWith is!
$this->var can be set to any string.
I tried
$this->var = "${preDefinedStringToTestWith}"
but this doesn't get expanded.
Uh! Shouldn't it work?
$this->var = $preDefinedStringToTestWith
For certain reason $this->var can only be set to a string and not to a
variable!
Any suggestions?
I don't understand what you are trying to do,
I do only have control over the content of this variable itself (Comes from
$_REQUEST) - not over the code.
but maybe you are trying to achieve something like:
<?php
class Test {
var $var = '';
function Test() {
$this->var = "theVariableName"; // Hold variable name
$theVariableName = "whatever you want";
if (${$this->var} == $theVariableName)
echo ${$this->var}." is equal to ".$theVariableName;
else
echo "bad dog! stop it!";
}
}
new Test();
?>
Nearly, but I can only alter the content of $var itself!
I cannot change the comparison.
Comparison is always
if ($this->var == $preDefinedStringToTestWith)
