Strange problem Max function cannot recognize parameters

Php

$CHRW = $this->getarrstringwidth ($chars, ",", 0, true); Array_walk ($CHRW, Array ($this, ' getrawcharwidth ')); $ Maxchwidth = max ($CHRW);

Report such a mistake Max () [Function.max]: Array must contain at least one element
I output $CHRW content before the Max function, which is an array ([1]=>6.35 [2]=>6.35 [3]=>6.35]

Reply to discussion (solution)

If I write Max (array (6.35,6.35,6.35)), the error disappears

Do the great gods know what's going on?? Why does the MAX function not recognize this parameter

This is the code of the Tcpdf class, I did not error local, but on the server on the error

$CHRW = $this->getarrstringwidth ($chars, ",", 0, true); Array_walk ($CHRW, Array ($this, ' getrawcharwidth ')); $ Maxchwidth = max ($CHRW);

The Max function must be able to put the variable, error description inside the array is problematic, array ([1]=>6.35 [2]=>6.35 [3]=>6.35]
I don't feel right about this array.

I'm sorry, that's my handwriting, that's it.
Array
(
[0] = 6.35
[1] = 6.35
[2] = 6.35
)

Array must contain at least one element
The array must contain at least one element
The array is like this
Array
(
[0] = 6.35
[1] = 6.35
[2] = 6.35
)
There are elements inside the array.

Var_dump ($CHRW) Look what it is.

Array (3) {[0]=> float (6.35) [1]=> float (6.35) [2]=> float (6.35)}

PHP is not mistaken, he said is empty so is empty!

$CHRW = $this->getarrstringwidth ($chars, ",", 0, true);
Var_dump ($CHRW);
Array_walk ($CHRW, Array ($this, ' getrawcharwidth '));
Var_dump ($CHRW);
$maxchwidth = max ($CHRW);

See for yourself.

I did as you said, and looked at each other, but the output was
Array (3) {[0]=> float (6.35) [1]=> float (6.35) [2]=> float (6.35)}

And, oddly enough, Max has an error, but my echo $maxchwidth turned out to be 6.35.

And locally yes, the server is wrong

Are the var_dump in your local test? To test on the wrong server.

Then you'll have to check if there's another place to use Max ().

Well, that's the test on the server.

To specify the number of lines, say in this line

Use Array_values ($CHRW) to try out the array before max calculation

Thank you, I don't know what's going on.
