Mpdf: count(): Parameter must be an array or an object that implements Countable

[danielbarenkamp]

I found this bug / would like to have this new functionality

When generating the PDF I get the following error:

PHP Warning: count(): Parameter must be an array or an object that implements Countable in XXX/vendor/mpdf/mpdf/src/Mpdf.php on line 25892

Please add a check if variable is an array or object before.

This is mPDF and PHP version and environment (fpm/cli etc) I am using

7.0.3

See also #562 and #595. Could you provide a small example that let us reproduce this exactly?

How is Mpdf instantiated in your setup?
Which html is feeded into mPDF, such that it triggers this error? (please provide a _small_ html example)

This is useful for reproducing your case, and allows to create the unit test for this issue. Thanks!

I am getting a similar issue with PHP 7.2 installations - I think there are some new restrictions with this version. PHP <= 7.1 seems to be okay.

I get this error at vendor\mpdf\mpdf\classes\ttfontsuni.php line 613 where you see

for ($i = 0; $i < count($psName); $i++) {

In this case $psName is a string so the problem is fixed with strlen()

for ($i = 0; $i < strlen($psName); $i++) {

This might give some clue as to the cause elsewhere. However, I'm still struggling with this as after I fixed it and then reverted there error did not come back - so I must have some caching somewhere as well!!

@geofftech based on the class path you are using 6.x version of mPDF not compatible with PHP 7.1+.

This is already fixed in mPDF 7.x

Tengo un problema similar con las PHP 7.2instalaciones: creo _que_ hay algunas restricciones nuevas con esta versión. PHP <= 7.1parece estar bien

Recibo este error en la vendor\mpdf\mpdf\classes\ttfontsuni.phplínea 613 donde ves

for ($i = 0; $i < count($psName); $i++) {

En este caso $psNamees una cadena por lo que el problema se soluciona constrlen()

for ($i = 0; $i < strlen($psName); $i++) {

Esto podría dar alguna pista sobre la causa en otro lugar. Sin embargo, todavía estoy luchando con esto, ya que después de que lo arreglé y luego revirtí allí, el error no volvió, ¡¡así que también debo tener algo de almacenamiento en caché en algún lugar !!

Funciona , solo hay que tener cuidado al momento de desplegar en servidor ya que es un problema que aun no esta solucionado por parte de los creadores de la libreria entonces tocaria volver a modificarlo cuando ya se haya desplegado
