String handeling...

[louis_coetzee]

Hi,

 

I have a db entry called capability the capability of a language by a person. For Example: Language Afrikaans: RWS English: RS etc. R = READ ; W = WRITE ; S = SPEAK

 

Now what I want to do is, get this from the db to be able to edit this:

$capability = $row['capability'];

 

I need to identify which one's he is capable of:

$r = true;

$w = false;

$s = true;

 

Can anyone tell me how to do this? I did do a search on google, but still did not het clarity.

Thanks in advance.

Show us what code you have already done and we will work from there.

 

Remember to encase your code in the [ code ] tags.

the $capability variable is the one I am working with, like I said it will contain at most RWS, I don't have code, because I don't know how to search for 'R' in $capability, I want to search for example 'R' and if it is in the string, must return true, else false.

$capability = 'RW';

$r = $w = $s = false;
for($i = 0; $i < strlen($capability); $i++) {
$tmp = strtolower($capability{$i});
$$tmp = true;
}

echo 'Read = '.(($r) ? 'True' : 'False').'<br />';
echo 'Write = '.(($w) ? 'True' : 'False').'<br />';
echo 'Speak = '.(($s) ? 'True' : 'False').'<br />';

$capability = 'RW';

$r = $w = $s = false;
for($i = 0; $i < strlen($capability); $i++) {
$tmp = strtolower($capability{$i});
$$tmp = true;
}

echo 'Read = '.(($r) ? 'True' : 'False').'<br />';
echo 'Write = '.(($w) ? 'True' : 'False').'<br />';
echo 'Speak = '.(($s) ? 'True' : 'False').'<br />';

Thanks a lot, solves the problem, just for interest sake, ps I am a beginner... how does the $$tmp (two dollar signs) work? thanks

The "double dollar signs" are called variable variables.
