How do I capture PHP output into a variable?
In PHP, you can use the output control functions to capture the output of a PHP script into a variable. The two functions you can use for this are
ob_start()at the beginning of your script to turn on output buffering. This tells PHP to store any output generated by your script in a buffer instead of sending it to the browser.
Next, run the code that generates the output you want to capture.
ob_get_contents()to retrieve the contents of the buffer and store it in a variable. This function returns the contents of the buffer as a string.
ob_start(); echo "Hello, World!"; $output = ob_get_contents(); ob_end_clean(); echo $output;
This will capture the echo statement "Hello, World!" and store it in the $output variable.
You may also use ob_get_clean() function which will clean the buffer and return the output.
ob_start(); echo "Hello World!"; $output = ob_get_clean(); echo $output; // outputs "Hello World!"
It will return the output and clean the buffer both.
