O comportamento dessas funções podem ser modificado pelas configurações do php.ini.
| Nome | Padrão | Modificável |

| memtrack.enabled | "0" | PHP_INI_SYSTEM |
| memtrack.soft_limit | "0" | PHP_INI_ALL |
| memtrack.hard_limit | "0" | PHP_INI_ALL |
| memtrack.vm_limit | "0" | PHP_INI_ALL |

Here's a short explanation of the configuration directives.
memtrack.enabled
boolean
Disables or enables the extension. Default value is 0, i.e. disabled.
memtrack.soft_limit
int
Soft memory limit.
The extension checks memory consumption before and after executing an op_array and produces a warning is the difference between the two values is equal to or greater than the soft limit, but only if the function is not ignored.
Setting this option to 0 also disables both soft and hard limit warnings. Default value is 0, i.e. no warnings is produced.
memtrack.hard_limit
int
Hard memory limit.
The extension checks memory consumption before and after executing an op_array and produces a warning is the difference between the two values is equal to or greater than the hard limit, even if the function is ignored. Setting this option to 0 disables hard limit warnings completely. Default value is 0, i.e. no hard limit warnings is produced.
memtrack.vm_limit
int
Virtual memory limit (set on a process).
This limit is checked only on shutdown and a warning is produced if the value is greater than or equal to the limit.
This option is currently supported only on OSes where mallinfo() function is available (i.e. Linux).
memtrack.ignore_functions
string
A comma or whitespace-separated list of functions which are to be ignored by soft_limit. The values are case-insensitive, for class methods use class::method syntax.
