Correct-b) strstr(string,search,before_search)stringRequired. Specifies the string to search
searchRequired. Specifies the string to search for. If this parameter is a number, it will search for the character matching the ASCII value of the number
before_searchOptional. A boolean value whose default is "false". If set to "true", it returns the part of the string before the first occurrence of thesearchparameter.

stringRequired. Specifies the string to split
splitRequired. Specifies one or more split characters
**daca este apelat iar este de ajuns sintaxa strtok(" "); si va mai face inca o separare din ce a rams din sir si va afisa: mai.Se utilizeaza foarte bine in bucle while pentru a putea sparge un text mai lung in bucatele mai mici in functie de un anumit caracter(de exemplu dupa spatiu)

13)a,b si c
14) $var1=0;$var2= something;$var3= ;
Empty($var); Empty($var1); Empty($var2); Empty($var3);
a)true true true trueb)false true true truec)true true false trued)true false false truee)false false true fasle
Correct c)- daca exista ceva in variabila atunci afiseaza false, daca nu, afiseaza trueDaca variabila nu exista afiseaza true
