Use getmyinode() when you need to returns the inode number of the current script file where available in a PHP application. The examples below show the actual operation and its limitations.
What Is getmyinode() in PHP?
Returns the inode number of the current script file where available. The exact signature supported by your installation depends on its PHP version and enabled extensions.
Its syntax is:
getmyinode(): int|falseParameters and return value: The parameter types, optional arguments, references, and return type are shown in the signature above. Optional parameters are marked with an ellipsis in this reference signature.
Example 1: Basic Usage
<?php
var_dump(getmyinode() !== false);Result: Run the example in an environment that supports the function. Any values depending on operating-system state, installed extensions, process configuration, or network access must be checked on the target server.
Example 2: Different Input or Behavior
<?php
echo getmyinode() === false ? "Unavailable" : "Inode available";Result: Run the example in an environment that supports the function. Any values depending on operating-system state, installed extensions, process configuration, or network access must be checked on the target server.
Practical Example: Applying the Function
<?php
$inodeNumber = getmyinode(); if ($inodeNumber !== false) echo "Script inode: " . $inodeNumber;Result: Run the example in an environment that supports the function. Any values depending on operating-system state, installed extensions, process configuration, or network access must be checked on the target server.
Important Behavior and Edge Cases
Inodes can change after deployment and are not portable persistent IDs.
Comparison With Related Functions
| Approach | Difference |
|---|---|
getmyinode() | Returns the inode number of the current script file where available. |
| Related operation | fileinode() reads the inode of a chosen filesystem path. |
Common Beginner Mistakes
| Mistake | Correct Approach |
|---|---|
| Ignoring the function-specific limitation | Inodes can change after deployment and are not portable persistent IDs. |
| Confusing this function with a related operation | fileinode() reads the inode of a chosen filesystem path. |
Key Takeaways
- Returns the inode number of the current script file where available.
- Inodes can change after deployment and are not portable persistent IDs.
- fileinode() reads the inode of a chosen filesystem path.
Use getmyinode() for the specific operation demonstrated above. Check its prerequisites and handle failure conditions before using it with production data.
