Find PHP ini file

 

php -i | grep "Loaded Configuration File"
 
 
 php -i | findstr /c:"Loaded Configuration File"

The two commands provided are used to determine the path of the PHP configuration file (php.ini) that is currently loaded by the PHP interpreter. Below, I’ll explain what each command does and why there are two different versions.


Breakdown of the Commands
Common Part: php -i
  • Both commands start with php -i.
  • This runs PHP from the command line and outputs detailed information about the PHP configuration, including settings, extensions, and the loaded configuration file.
  • It’s similar to calling the phpinfo() function in a PHP script but displays the output in the terminal.
The Pipe: |
  • The | symbol is a pipe, which takes the output of php -i and sends it as input to the next command for further processing.
First Command: php -i | grep "Loaded Configuration File"
  • What it does:
    • grep is a command-line tool used in Unix-like systems (e.g., Linux, macOS) to search text for lines that match a specific pattern.
    • Here, it searches the output of php -i for the exact phrase "Loaded Configuration File".
  • Output:
    • It will display the line containing "Loaded Configuration File" and the path to the php.ini file, such as:
      Loaded Configuration File => /etc/php/8.3/cli/php.ini
Second Command: php -i | findstr /c:"Loaded Configuration File"
  • What it does:
    • findstr is a Windows command-line tool that searches for text patterns, similar to grep.
    • The /c: option tells findstr to search for the literal string "Loaded Configuration File".
  • Output:
    • Like the grep version, it shows the line with the path to the loaded php.ini file, for example:
      Loaded Configuration File => C:\php\php.ini

Purpose of the Commands
  • Both commands filter the extensive output of php -i to show only the line that specifies the loaded PHP configuration file (php.ini).
  • This is useful for:
    • Checking which configuration file PHP is using.
    • Troubleshooting issues related to PHP settings.
    • Verifying the environment setup.
Why Two Versions?
  • The difference between the commands lies in the operating system they are designed for:
    • grep is a Unix-like tool, so php -i | grep "Loaded Configuration File" is used on Linux or macOS.
    • findstr is a Windows tool, so php -i | findstr /c:"Loaded Configuration File" is used on Windows.
  • They achieve the same result but use tools native to their respective operating systems.

Example Usage
  • On Linux/macOS:
    php -i | grep "Loaded Configuration File"
    Output:
    Loaded Configuration File => /etc/php/8.3/cli/php.ini
  • On Windows:
    php -i | findstr /c:"Loaded Configuration File"
    Output:
    Loaded Configuration File => C:\php\php.ini
Conclusion
The commands php -i | grep "Loaded Configuration File" and php -i | findstr /c:"Loaded Configuration File" are two ways to find the location of the php.ini file loaded by PHP. Use the grep version on Unix-like systems (Linux/macOS) and the findstr version on Windows. They both make it quick and easy to pinpoint the active configuration file from PHP’s detailed output.

Reading and Writing Operation of SRAM

Image
The diagram below is illustrate Static Random Access Memory (SRAM)Cell for the explanation. SRAM cell is make up of 2 inverters are cross-connected to form a latch .The latch is connected to 2 bit line by transistor T1 and T2 . T1 and T2 can switch opened or closed under control of word line.When word line is ground level, the transistors are turned off and the latch retrains its state. During the Read Operation ,Word line is activated to close switches T1 and T2 . If the cell is in state 1; the signal on b line is high and the signal on b’ line is low.The opposite is true if the cell is in state 0.Thus, b and b’ are always complements of each other’s. The sense /write circuit at the end of the two bit line monitors their state and sets the corresponding output accordingly. While in Write Operation ,the Sense/Write circuit drives bit lines b and b’, instead of sensing their state.It places the appropriate value on bit line b and its complement on b’ and activate the word ...

Reading & Writing Operation of DRAM

Image
In Dynamic Random Access Memory CELL , transistor acts as a switch to Close (allowing current to flow) when voltage applied in address line or Open (no current flow) when no voltage applied in address line.Address Line also known as word line .Which use to signal the transistor to close or open. During the Write operation ,a voltage is applied on the bit line and a signal applied to the address line to close the transistor.Then the voltage applied on the bit line will transfer to capacitor and store in the capacitor However the capacitor has tendency to discharge and has to refresh to maintain the bit. While in Reading Operation ,the instruction find the bit store using the address line to read the data or bit. When the address line is selected ,the transistor turns on and the charge stored on the capacitor is fled out onto a bit line and to sense amplifier. Sense amplifiers compare the capacitor voltage to reference value to determine the logic 1 or logic 0.The read out from ...

Method to Convert from Stream to Json C#

Recently I was using the C# HttpClient to make REST request but I found that is was quite troublesome so I have changed to using HttpWebRequest instead. So want the HttpWebRequest result is return it was in Stream form. I not able to convert it into Json. this is the method i convert the stream to JSON. HttpWebResponse response = ( HttpWebResponse ) requirejs . GetResponse (); Stream stream = response . GetResponseStream (); StreamReader sr = new StreamReader ( stream ); var serializer = new System . Web . Script . Serialization . JavaScriptSerializer (); var jsonObject = serializer . DeserializeObject ( sr . ReadToEnd ()); As you can see that jsonObject is an object. Now you can parse it into the Json(JsonObject); If you have any question can leave a comment below.
