# PHP 5.2 linting with MAMP

Syntax checking PHP files for 5.2 compatibility. The really easy way.

## MAMP

These days I rarely use MAMP with alternatives like a local set up, Docker, Vagrant and its WordPress specific variations.
Still I consider MAMP an asset and a “just works” solution that I come to appreciate in dire times.
The local stack comes in a PRO version that’s worth its cost to me but the free version of it still packs PHP in its 5.2.17 version that’s easy and ready to use.

## WordPress minimum requirements

WordPress still lists that version of PHP as its minimum required one and I want to think some plugins I’ve written “should” work on PHP 5.2.
The most recent case with Restricted Content framework plugin is that I wanted a quick way to lint my code against the older version of PHP without too much hassle.

## CLI scripts

Since the older PHP version is located in the MAMP application accessing it on a Mac, is easy and convenient.
The script I came up with is a modification of this one and here is the code

#!/bin/bash

for file in find .
do
EXTENSION="${file##*.}" if [ "$EXTENSION" == "php" ] || [ "$EXTENSION" == "phtml" ] then RESULTS=/Applications/MAMP/bin/php/php5.2.17/bin/php -l$file

if [ "$RESULTS" != "No syntax errors detected in$file" ]
then
echo \$RESULTS
fi
fi
done



copy and paste in a file like

cd /usr/local/bin
touch lint52
pbpaste > lint52
chmod +x lint52



Navigate then to any folder that should be lint-ed and run the command

cd /Users/Me/MySites/MyWp/wp-content/plugins/my-plugin/src
lint52



and see it pointing errors.
