T_String is the common parse error associated with the creation of PHP files. This problem is observed when an apostrophe sign is added in between a code that has been delimited with apostrophes, generating huge conflict with the PHP document. To ignore an apostrophe within a PHP code, a slash must be inserted in front of the apostrophe excluded from the command. A PHP error also arises when a ';' sign is not inserted at the end of the command. PHPbeing a program demands a logical flow of commands. This is the simple step that needs to be taken to avoid T_String parse errors while coding PHP commands.
A common problem that may arise while creating a PHP file is the parse error T_String. This happens when an apostrophe is entered in a series of codes already being delimited by apostrophes. Having several apostrophes in a same command creates a huge conflict within the PHP document.
echo 'we don't know';
How to solve the problem
The above example can be solved simply by telling the program where to ignore the apostrophe, by inserting a slash before the apostrophe that is not being used as a command. Hence, the code above will be written as:
echo 'we don\t know';
The Parse Error can also arise if the programmer has forgotten to insert the ; symbol at the end of the command.
echo 'we \"don't\" know'
Note: PHP is a simple program that asks for much attention. You should not have any problem with it if you pay enough attention to the logical flow of the program.
