The var_dump() function output in PHP is incomplete Problem

In the PHP development environment, after installing the xdebug module, the output results of var_dump() will be easier to view, but by default, the output results of var_dump() will change: too many array elements No longer displayed, the string variable will only display the first N characters, and deeper array elements will also be displayed as ellipses.

This will cause some inconvenience, but we can modify the php.ini configuration file to solve this problem.

In the xdebug node in php.ini, add or modify the following parameters

xdebug.var_display_max_children=128
xdebug.var_display_max_data=512
xdebug.var_display_max_depth=5

Among them:

xdebug.var_display_max_children is the maximum number of elements allowed to be displayed in an array

xdebug.var_display_max_data is the maximum number of bytes a string variable is allowed to display

xdebug.var_display_max_depth is the maximum number of dimensions an array is allowed to display

Finally restart the apache service.
