## Checking for `E_STRICT`

If you only have a single script to check, you can pick up `E_STRICT` errors using PHP's commandline lint facility:

php -d error_reporting=4095 -l script_to_check.php

For larger projects, the shell script below will achieve the same task:

    #!/bin/sh

    directory=$1

    shift

    # These extensions are checked
    extensions="php inc"

    check_file ()
    {
      echo -ne "Doing PHP syntax check on $1 ..."

      # Options:
      ERRORS=`/www/php/bin/php -d display_errors=1 -d html_errors=0 -d error_prepend_string=" " -d error_append_string=" " -d error_reporting=4095 -l $1 | grep -v "No syntax errors detected"`

      if test -z "$ERRORS"; then
        echo -ne "OK."
      else
        echo -e "Errors found!\n$ERRORS"
      fi

      echo
    }

    # loop over remaining file args
    for FILE in "$@" ; do
      for ext in $extensions; do
         if echo $FILE | grep "\.$ext$" > /dev/null; then
           if test -f $FILE; then
             check_file "$FILE"
           fi
         fi
      done
    done
