Strcmp
From SA-MP Wiki
Strcmp
strcmp can be used to compare whetever two strings are the same, but has (as all functions), problems with cyrillic characters. Another problem of this function is, if one string or both is empty, strcmp will return 0 (same when strings are the same).
(const string1[], const string2[], bool:ignorecase, length)
| string1 | The first string to compare. |
| string2 | The second string to compare. |
| ignorecase (optional) | When set to true, the case doesn't matter - HeLLo is the same as Hello. When false, they're not the same. |
| length (optional) | When this length is set, the first x chars will be compared - doing "Hello" and "Hell No" with a length of 4 will say it's the same string. |
| Returns | 0 if the strings are the same. |
Good examples of using strcmp can be found at the Using strcmp()-Tutorial.
NOTE:
If you don't and compare one string from a textfile with an other variable strcmp will not return 0 (only if length is larger then the string in the file)
This is because the string in the file has \r\n for the line return at the end, so if you use strcmp to compare textfile strings do it like this:
strcmp(stringfromvariable,stringfromtextfile,true/false, getlength(stringfromvariable))
so the \r\n in your file will be ignored because it is out of the range to compare!
