1. parse error: syntax error

Cause: Most often occurs when you forgot a semicolon (;) or made a typo.

Fix: Check once again your PHP code to see that an incorrect punctuation or misspelled keywords are used. Syntax [highlighting] with a code editor.

2. The Undefined Variable Error.

Reason: You are attempting to apply a variable prior to defining it.

Fix: Never use an uninitialized variable. Let the error_reporting(E_ALL) be enabled in development to be able to detect problems early.

3. Undefined call to Function

Cause: You are using a non-existing or forgot to include a file in the call to a function.

Fix: Spell out proper name of your function and make sure that you have default files with require or include.

4. maximum execution time exceeded error number.

Reason: Your script is very slow.

Fix: Either clean up your code or raise the limit of the execution time in the php.ini by using max_execution_time.

5. Connection Error - Database

Cause: Wrong database name or password or server did not respond.

Fix: Check username, password, hostname and database name. Connection to your database should also be tested separately.

6. Headers Already Transmitted

Cause: Output is sent prior to modification of HTTP headers.

Fix: No echo, no whitespace preceding header() calls. Direct output on the heels of changes in the head.

7. Out Of Memory

Cause: you consume more memory than the scriptlimt.

Fix: Set memory_limit in php.ini or can optimize code to make it use less memory.

8. Error 0. File Not Found

Reason: The file you want to include/open can not be found by the script.

Fix: Path, permissions of files. Make use of absolute paths.

9. Deprecated Functions

Caused by: You are using functions deprecated in the recent releases of PHP.

Fix: Refactor to replace with those functions with support. See the PHP documentation to see alternatives.

10. Permission Denied
