[socieboy]

I have the same problem. any fix on that?

[asbrito]

I also have the same problem.

[webissupport]

This might not be ideal but this is working and did not came across any side issues yet: on line 3321 of the Style.php script cast the $val variable to integer: round((int)$val)

[lenomosh]

On Style.php on line 3321
change round($val) to round((int)$val)
In my case it was on line 3304
So it is better to find the following statement

        if (round($val) != $val && $val !== "auto") {
            return;
        }

and change it to

        if (round((int)$val) != $val && $val !== "auto") {
            return;
        }

[nursandiid]

please, check your php version.
I also have the same problem if I use php v.8 , but after I swicth to version 7 the problem was resolved

[JuanDeLeon]

Fixed for me after upgrading to 0.9.0
This was my composer update log:

• Downloading dompdf/dompdf (v1.0.2)
• Downloading barryvdh/laravel-dompdf (v0.9.0)
• Upgrading dompdf/dompdf (v0.8.6 => v1.0.2): Extracting archive
• Upgrading barryvdh/laravel-dompdf (v0.8.7 => v0.9.0): Extracting archive

[carletonm]

This seems to be an issue that occurs with php 8. They need to fix the style.php file and change round($val) to round((int)$val). As lenomosh said.

[aromka]

Also occurs with PHP 7 if you use strict types. Is there an update on this?

[charliedearce]

its working on php v7.4.22

This has been fixed in dompdf with a better solution than the ones posted above.

Can you confirm when the fixed version will be included in Wordpress.

dompdf/dompdf#2670

NEVER EVER CHANGE VENDOR FILES EVER!!!!!!!!!!!!!!!!!!!!!!!!
This is a type error, in short it means your current php version doesn't match with the one required by the package.Just change the dompdf package to a version that matches your php version

[agitnaeta]

using php 8.0
apache 2.4.53
"laravel/framework": "^8.12",
"barryvdh/laravel-dompdf": "^0.8.7",
