detect numeric values make no changes

[lovephp]

trying to replace value of strings from array only if its not numeric but if numeric make no changes, the calues are somewhat like this

 

abcd-efgh

xyz-abc

alpha-lima-lima

bravo-charlie-charlie

 

and also like

 

100-500

1000-5200

100000-800000

 

now what i wish to achieve is those which are not numeric those stings im trying to remove the - with a space but if its numeric value - should stay intact

 

 
foreach ($_GET as $key => $value) {
$key = str_replace('_', ' ', $key);
if(!is_numeric($value)){
$value = str_replace('-', ' ', $value);
}
echo '<small><b>'.ucstring($key). ':</b> ' .ucstring($value). ',</small>';
}
echo '<br/>';
}
 

 

but doing so the code above making no changes to the numeric values even the numeric values - gets removed

I don't know which is worse. Your English or your PHP. Did you even read your text prior to hitting the Post button?

 

Ok - you want to modify the non-numeric values only. Got that. And you only want to change the values. So why do you start out changing the key first thing? Using is_numeric is going to fail (tried it) because having that dash in the value automatically makes it NOT numeric. If your pattern is consistently as you stated, you could do a trial replace from _ to a dot which would then be acceptable as a numeric value. THEN you could make your ultimate change from dot to null.

 

PS - you do realize that when the foreach completes, the values in the GET array will not be altered with your current code.

well the key values comes as abc_def so i needed to remove the _ from the key, and yes my English is definitely bad but i try hard to improve

So - English is not your native language. In that case I'm sorry for picking on you but I did not think that was the problem. You actually have pretty good command of the language - I just thought it was American Millennials laziness

//Create function to be called using array_map()
function updateDataArray($value)
{
    //Check if any letters exist
    if(preg_match("#[a-z]#i", $value))
    {
        //Contains a letter replace "-" with space
        return str_replace("-", " ", $value);
    }
    //Does not contain letter, return unchanged value
    return $value;
}
 
$original_data = array(
    'abcd-efgh', 'xyz-abc', 'alpha-lima-lima', 'bravo-charlie-charlie',
    '100-500', '1000-5200', '100000-800000'
);

//Call the function above as a parameter in the array_map function
$modified_data = array_map('updateDataArray', $original_data);
 
echo "<b>Before</b><pre>" . print_r($original_data, true) . "</pre>";
echo "<b>After</b><pre>" . print_r($modified_data, true) . "</pre>";

Before

Array
(
    [0] => abcd-efgh
    [1] => xyz-abc
    [2] => alpha-lima-lima
    [3] => bravo-charlie-charlie
    [4] => B-B-D
    [5] => 100-500
    [6] => 1000-5200
    [7] => 100000-800000
)

After

Array
(
    [0] => abcd efgh
    [1] => xyz abc
    [2] => alpha lima lima
    [3] => bravo charlie charlie
    [4] => B B D
    [5] => 100-500
    [6] => 1000-5200
    [7] => 100000-800000
)

And that is how the problem is solved by those who understand regular expressions!

 

Note Psycho mistook your underscores for dashes so correct his code accordingly.

Well, I wrote the code based on his initial post which stated

But, looking at his last post he magically changed the requirement from dashes to underscores.
