read file
 
How can i store lines data in array?
Its not working properly sometimes it just print 1st array or sometimes last.
Code

PHP Code:
new StoreData[128][128];
new testfile[255];

public loadStoreData()
{
    get_configsdir(testfile,255)
    format(testfile,255,"%s/test.ini",testfile)

    new line;
    new file = fopen(testfile,"r")

    if(file)
    {
        new data[128]
        while(fgets(file, data, 127))
        {
            if(data[0] == ';' || !data[0]) continue
            parse(data, data, 127)

            StoreData[line] = data
            line++
        }
        fclose(file)
    }

    for(new i = 0; i < sizeof line; i++){ 
        server_cmd("say %s", StoreData[i]);
    }
}

By using dynamic arrays. This is the code I use in nearly all my plugins:

PHP Code:
ReadFile()
{
    new szFilename[256]
    get_configsdir(szFilename, charsmax(szFilename))
    add(szFilename, charsmax(szFilename), "/FileName.ini")

    new iFilePointer = fopen(szFilename, "rt")

    if(iFilePointer)
    {
        new szData[128]
        new Array:myArray = ArrayCreate(128)

        while(!feof(iFilePointer))
        {
            fgets(iFilePointer, szData, charsmax(szData))
            trim(szData)

            switch(szData[0])
            {
                case EOS, ';', '#': continue
                default:
                {
                    ArrayPushString(myArray, szData)
                }
            }
        }

        for(new i; i < ArraySize(myArray); i++)
        {
            server_cmd("say %a", ArrayGetStringHandle(myArray, i))
        }

        ArrayDestroy(myArray)
        fclose(iFilePointer)
    }
}

} 
can you modify the current code instead of dynamic array bit easier for me.

Re: read file
 
Easier for you doesn't mean more efficient. Not using dynamic array means that you must have a limited amount of space where you can store the lines. With dynamic arrays this space is, well, dynamic and you don't need to worry about anything failing.

It's really not complicated at all. You can use the code as is, but I suggest you use the array with a global variable.

PHP Code:
// this creates the array
// it's the same as "new StoreData[128][128]" you used, only here you're not limited to 128 lines
// you should define a global variable and then use ArrayCreate() inside plugin_init() or before reading the file
new Array:myArray = ArrayCreate(128)

// this adds the string (the entire line) in the array
// same as using "StoreData[line++] = data"
ArrayPushString(myArray, szData)

// this gets the number of elements (strings) stored in the array
// same as using "sizeof(StoredData[])", although this one should be cached
ArraySize(myArray)

// this is a neat "trick" for retrieving a string from a dynamic array
// same as using %s + StoredData[i]
ArrayGetStringHandle(myArray, index)

// the only difference is that you must destroy the array when you're done using it
// if you assigned it as a global variable, it's best to destroy it in plugin_end()
ArrayDestroy(myArray)

ArrayDestroy(myArray) 
Oh Thanks for explaination , I will try this one.

} 
bdw whats error in this? why this one not working

1. You're using "parse" for no reason. See its documentation to understand what it does - https://amxx-bg.info/api/string/parse

2. In the for-loop, you're using "sizeof line" instead of "sizeof StoredData", so basically you're retrieving the size of an integer, which is always equal to 1.

fixed bdw what can be used then instead of parse?

Re: read file
 
How can i read separately for example;
StoreData1 and StoreDate2 by using this array method.
File: file.ini
PHP Code:
[StoreData1]
SD1.1
SD1.2

[StoreData2]
SD2.1
SD2.3 


PHP Code:
ReadFile()
{
    new szFilename[256]
    get_configsdir(szFilename, charsmax(szFilename))
    add(szFilename, charsmax(szFilename), "/FileName.ini")

    new iFilePointer = fopen(szFilename, "rt")

    if(iFilePointer)
    {
        new szData[128]
        new Array:myArray = ArrayCreate(128)

        while(!feof(iFilePointer))
        {
            fgets(iFilePointer, szData, charsmax(szData))
            trim(szData)

            switch(szData[0])
            {
                case EOS, ';', '#': continue
                default:
                {
                    ArrayPushString(myArray, szData)
                }
            }
        }

        for(new i; i < ArraySize(myArray); i++)
        {
            server_cmd("say %a", ArrayGetStringHandle(myArray, i))
        }

        ArrayDestroy(myArray)
        fclose(iFilePointer)
    }
}

Re: read file
 
I recommend you to use ini parser in this case.
